"I'm open to a peer-reviewed study" is going to be my answer to everything I don't agree with from now on
Yar maw’s bad in bed
I remember when experimental verification was all that required. But why waste energy proving something when you can just assume its true, get a government grant and publish an peer-reviewed inconclusive study instead? Indeed, you could spend a whole lifetime that way and retire wealthy without ever having proven anything. Modern Science is truly a wonder!
Very disingenuous
Just say you disagree
One study is not sufficient evidence for most things
@@Mrch33ky well, you could also read the study presented to you and see if it makes any sense... ;-)
You cant try out everything yourself and for several fields of science there's experts with better equipment who tend to publish their findings in... Peer reviewed studies!
Or sometimes on CZcams, just for fun, so here you go! ;-)
Yet your claims are reviewed by what exactly.... If I always asked for a peer reviewed study for every single hint I ever got, I probably couldn't even read, so there'd be no point in asking for a study. Just listen to people and see if they make sense.
My mom has a disability that makes drinking difficult so she drinks really slowly, and her hot drinks tend to be cold by the time the finishes them. She recently got an ember mug as a gift and she said she loved it!
Awwww this makes me really happy :' ) As a person with a disability I love seeing when technology can bring even the slightest improvement to someone like this.
This actually made my eyes sweat a bit.
@@pabloschultz5192 It's a terrible day for rain.
that's probably the best thing the people who designed the Ember could hear :)
A lot of "ridiculous" products are actually really helpful accessibility aids. Not surprised to learn that the Ember is no exception
" If you're on that bandwagon, i'm open to a peer reviewed study...."
definitely one of your best lines James :)
It was so good I watched it a couple of times and then thought, "I hope he's not thought I'm on the bandwagon and that's why I'm rewatching it..."
If you want to do a follow-up, here are some interesting and very inconvenient ways to re-heat coffee:
- Sous-vide (lower heat for a longer time)
- Passing through a nespresso coffee maker without a capsule (how coffee was meant to be created)
- Oven (maybe just the same as using a pot? would it make a difference to use a broiler?)
- Creme brulee torch (very high heat to a small area at a time)
- Open fire grill
- Explosives (no don't try this one actually)
I would watch your CZcams channel
Thanks, it helps
While at it also add flamethrower as a possible reheating instrument
What's a broiler
@@alinaqirizvi587 broiling is cooking something from the top down. Some people call it grilling for some reason. The broiler is the top heating element in an oven
“I hate myself for how much I like this.”
This is why we love you.
James: runs a coffee roasting business with 25 employees
Also James: doesn't have a way to make coffee for more than 3 people
Lol thinking the same thing
Interesting, your comment has exactly 25 likes... I think his employees are saying something here lol
*at home.
And to be fair. There aren't many (manual) methods that can make great coffee for more people that is not very big and bulky. Maybe you can make for 4 people in a large french press.
The studio is several miles from the roasting company, which hopefully explains why they have the batch brewers and I don’t
@@jameshoffmann I always thought the "kitchen counter" studio was in upstairs in Squaremile. Guess not
Never throw out cold coffee. Freeze it in ice cube trays for use in frozen coffee drinks later
Brilliant
That's what I do too!
Smart… if you drink that kinda stuff.
I generally don’t drink cold coffees (no idea why, I just don’t).
If anything, pouring it into that plastic container is going to affect the taste...and probably have phthalate toxins
You can use them to cool your coffee to drinkable like he was commenting he did with plain ice. Then you’d not have to dilute it to be able to drink it right away.
I can't express how much I appreciate you messing up and rolling with it. Not redoing it, not trying to play it off. Not scrapping the video. Man, we need more people (professionals, with your level of success and following) to normalize messing up and not getting everything "perfect." You rock. But now I want an Ember mug (again) and my wallet hates you. Thanks for the great videos.
“I’m open to a peer reviewed study” James I love your forthright candor.
It's a sneaky way of getting someone else to invest time effort and money into a problem we all want solved haha
IIRC the peer reviewed studies I have seen show that cooking vegetables in the microwave actually preserves more nutrition that boiling or steaming. They cook faster so degrade less, with boiling and steaming both having water retaining nutrients from the vegetables as well.
Surely we should all remain responsive to evidence and data.
The burn was real
I have FAR less patience than James when it comes to people saying microwaving food is bad because the molecular structure gets changed. I usually just raise my voice and go, "It's called cooking! All cooking changes the molecular structure of food! Did you not cook an egg in science class!?"
Perhaps, I will go farther with James's line and leave it at that. At least I won't get disapproving looks from my wife as I yell, rant, and rave about basic science competency.
I pour my cold coffee into one of those floppy hot water bottles and then stick that under my cat for an hour to reheat coffee.
hilarious!
Now *there* is a wildcard method.
So funny
Greenest method yet! ...however *unhappy cold tummy cat noises*
I pass my coffee backwards through a civet cat to re-heat it. This method is best for making kopi luwak. Two passes through a civet, one forward, one reverse. Delicious (NOT!!!).
It was life changing when i figured out I could reheat coffee "successfully" by doing it in 22 second bursts and no longer than that and stirring the coffee before shutting the door to keep the liquid moving to prevent hot spots. It sometimes takes 2-3 heats but so much better and worth it to do it that way.
Might just try it! Thx 🙏
Just lower the duty cycle on the microwave. Use the reheat button or put it on 50 percent for a minute. Find the right setting and you don’t have to baby it so much.
I reheat in u-wave 40 seconds @ 70% or 50 seconds if cup is closer to full. For me, the key is to avoid overheating which imparts a burnt flavor. I’ve recently added a cup warmer with 170-150-130 and that helps me finish the cup before it cools.
@@charlesmoore1762 I just watched a video that said drinking beverages over 140 degrees F can be associated with esophageal cancer so the 130 would be the best setting when you're ready to drink.
Old or basic microwaves make pauses if set to anything other than maximum power. Notice the sound it makes when defrosting: air blows all the time but heats only now and then.
When reheating with a microwave, I've found something that makes a significant difference to the taste. Since heat rises, as the microwave is running, the coffee in the cup at the top becomes significantly hotter than the coffee in the bottom. So I heat about 2/3 of the way to target temperature, then remove the cup and stir from bottom to top, then heat the rest of the way. It tastes much better than if you overheat the top in order to have the top and bottom average to your target temperature. This way of stirring halfway through prevents you from ever having to overheat any of the coffee, and the coffee really is noticeably better.
You gave me idea to spin coffee in the cup before putting into microwave, so it will swirling while heating up so you don't have to interrupt while achieving even temperature...
@@odmahizasvega5984 please let us know the results
I would think that swirling the coffee could help to compensate for the microwave not heating evenly horizontally, but that you would still need to stir bottom to top to even out the temperature vertically. Also, that you would need to pause partway through and stir bottom to top in order to avoid overheating the top half of the coffee on your way to an average which is your target temperature.
What is your power setting and times used for each heating cycle? How many ounces r u heating?
While I'm not saying that your experiences are wrong (though a blind taste test would be needed to confirm), there is a flaw in the logic here: If this was due to hot coffee rising, then the coffee would be causing its own circulation, as that assumes coffee low down in the cup is being heated significantly. After all, when parts of a liquid are heated and rise up, cooler parts sink down to replace them. This causes a circular flow assuming the input of energy is steady - as the colder coffee at the bottom is itself heated, it would too seek to rise as the hotter coffee up top cools slightly. For this to add up, there needs to be another parameter added: that the microwave mainly heats the coffee in the top of the cup. This is definitely not unlikely, as the energy dispersal patterns inside of a microwave are extremely uneven, but this then removes the "hot coffee rises" part from the equation, aside from it effectively stopping the hot coffee from being circulated downwards and replaced by colder coffee. So, stirring halfway might very well be beneficial, but it would be dependent on the heating patterns of your specific microwave, as well as things like cup height, the microwave duty cycle, etc. Still, this is really interesting - I've got a really bad microwave, and I've seen how it can overheat things really badly in specific spots, so it makes sense that the same could happen in a liquid.
I really like how James hates how much he loves the ember hahaha
It seems perfomative. The subtext is “don’t flame me for liking this expensive, powered thing-I’m flaming myself for you.” Just own what you like.
@@ladyflimflam nah, it's because he really dislikes pretty much everything "smart" when it comes to making coffee. He's mentioned in multiple videos that he doesn't like to complicate his routine with e.g. smart scales and Bluetooth and updates and apps etc.
He knows it's weird (almost hypocritical?) that he does like the Ember so he hates that haha.
Well it's also a thing of 'oh this is terrible but if you're willing to pay for it here's my website', which honestly is fine by me because for advertising these are very entertaining videos anyway!
It makes sense. There are a lot of "smart" things that are objectively bad - glued in batteries, planned obsolescence, waste, spying on you, expensive, bricked once the provider decides to switch of the needed cloud service, etc.
Its still fine to enjoy them personally. Being aware of the problems and making educated decisions about that already goes a long way.
It reminds me of how I feel about my Nespresso; I know it's objectively worse than a lot of other options, but I've gotten spoiled with how fast it is and therefore created a morning latte habit that can't be done with a "better" machine without rearranging my morning. I really like it on a day-to-day basis but I hate that I've made myself dependent on something less sustainable. Technology can be a mixed blessing like that.
So we've all accidentally been coffee reheating experts by using the microwave?
Mummy knows best
There's nothing wrong with microwave ovens, especially in modern times. They simply heat up the water molecules in food, and obviously liquids. They do not alter or reduce the nutrients in your food. But hey, each to their own.
I’d like to point out, how much I like how you’re embedding your sponsorships! Super neat: “While the cups are being switched, I’m going to tell you …” So it actually feels like we’re using the meantime wisely. Great mind trick.
I hate it.
The sound of coffee slurps is immensely animated.
Lol same
I'm just saying this could be a birth of a meme
Ah, I see you’re new here. Welcome to the wonderful world of coffee cupping.
And so is the flavor
The slurp sound consistency was amazing
“Microwaves take the nutrients out of your food!”
My HotPocket: “nutrients?”
You should watch jim gagiffin hot pockets standup, hilarious 😂
This is exactly why microwaves are bad: they encourage you eating garbage. I don't have a microwave and I cook all my meals.
@@jeroboam4486 microwaves don't actually destroy nutrients though. That's just a myth.
Hot Pockets fucking rule
"Food cooked in a microwave oven is as safe, and has the same nutrient value, as food cooked in a conventional oven. The main difference between these two methods of cooking is that microwave energy penetrates deeper into the food and reduces the time for heat to be conducted throughout the food, thus reducing the overall cooking time." www.who.int/news-room/q-a-detail/radiation-microwave-ovens
"I often brew onto an ice cube or two.......that may be scandalous, I don't know." Hilarious James 😂.
If you put a tablespoon of sweetened condensed milk in an 8 oz glass, fill with ice cubes and fill with coffee. Stir until the milk in mixed in, You have veitnamese coffee.
I've found that putting fresh coffee in a really good thermos works for me. When I want some coffee, I pour just a little bit into a mug (maybe half an inch or so) and let it cool down. When it cools down below drinking temperature, I'll then pour enough from the thermos to bring it up to the temperature I like. As I drink the coffee and it cools down, just keep topping it off from the thermos. Kind of a lot of work, but it keeps me happy.
Thanks. The glass liner ones from back in the Jurassic worked better than anything except maybe steel. A thermal or double wall mug is pretty good, especially if it has a lid. My local coffee shop brews into large thermal carafes.
I use a £20 Contigo mug. Keeps my coffee warm for around 8 hours. I’ve driven the length of the U.K. before and still had drinkable coffee at the end.
I really want to see a confused James rank the coffees, not understanding why the steamer worked so well😂
Yes please upload that part as well
Yep, we need the out takes!
I also want the bit when they realized they messed up the labeling
This was the final confirmation I needed to pull the trigger on getting an Ember mug, I too am disabled so going back and forth from the kitchen with a hot drink is risky, I need good coffee to last and stay tasty! Thanks James, you've cost me over £200 so far this year and I am not even slightly annoyed!
@@zephyrm.6564 ugh. Gross. Did you say that? Woke nonsense
I love when he said "its tastin time" and tasted all over the place
*Vvvvvoip! Vvvooooip! Voooip!*
So you're telling me I can now buy the Ember Mug, then tell my wife "It was James's Idea"? Because I'm okay with that.
Well I did! Go for it!
I'm in lol
Selling something similar at Costco now. However, it's not travel friendly, so I just bring a thermos instead.
@@laurabrown2899 this is a coffee video. And a comment about a warm keeping mug... we dont want curtains
After reading all the rave reviews of the Ember Mug here, I went to look up the price ... I'm definitely not buying it!
Volume 2:
-Bain marie
-immersion circulator
-hot rocks
-flambé
-gas torch
IMHO Bain Marie is the best way to reheat coffee
I'd like to see a teapot set up heated with a tealight.
would love to see James with a gas torch
I just want him to find the most optimal way to reheat it with the microwave
One of my favorite potter channels John The Potter just created a ceramic drink heater that uses tea lights. It looks amazing.
Hot coffee drinkers: Ah! My coffee went cold!
Iced coffee drinkers: Ah, my coffee went cold. :^)
Both types: Ah! My Coffee went room temperature!
Moved into a new place and was without a microwave for a few days. I discovered the best way to reheat your coffee is to just put the mug onto the caraffe warmer on a drip-maker for a few minutes. It's a lot more gentle than a stove burner, and the mug acts as a big heatsink that transfers the heat more evenly and slowly than the thin glass caraffe. The coffee never gets warmer than the mug itself
I used that method for years while at work. Nowadays the new style mugs keep my coffee warm enough for long enough that I never reheat.
Nice idea
This actually confirms my lived experiences. I've been drinking coffee like it's my full time job for 35 years. I've cut it down to two pots a day (working with the common sense idea that 3-4 liters of caffeine wasn't good for any human), but I've had to work out how to stretch the pleasure of each pot as far as possible. Important note: I am a slow sipper. I'm never far from my cup unless I'm sleeping. Also, I take it black. This means my system is much easier to balance as all I'm adjusting is temp.
First, the minute the brew is done, I get it off the hot plate and into a good thermos. I do invest in good thermoses because they last and they're worth it. Second, I use a thermal travel mug as my primary coffee cup. This helps retain the heat of the individual cups as long as possible.
Third, I reheat the last of my cup with the next hot addition. Never allowing the cup to completely empty and topping it off with fresh, hot coffee takes me pretty far. I've been doing this long enough that I instinctively can hit my preferred drinking temp easily. I know how cold the coffee in the cup is, I know how hot the coffee in the thermos is, and I know the ratio of cold to hot that I need to make me happy. This means I might end up with several half cups of perfect coffee and I'm very content with that.
But it doesn't matter how good your thermos is, after about 4 hours, the addition of hot coffee trick won't work. You're going to lose heat. Your thermos coffee hits perfect drinking temp and it's only getting colder as time goes by. At that point I do drain the whole cup. And I only pour half cups until the rest of the pot is gone. These steps are usually sufficient to do the trick and I'm kept in hot coffee that's a pleasant drinking temperature for about six hours at a time.
But sometimes things go awry. I end up with a full cup of cold coffee, it's the last of that pot and I'm not ready to make pot #2 yet.
This is when I use the microwave. For me, the trick is to JUST get the coffee right up to where I want it. Overshooting the mark will ruin the brew 100% of the time. I probably only have to resort to this once or twice a month.
To give an idea of how much I like MY coffee and MY system, I never actually buy cups of coffee anywhere. Ever. It's too hot, too strong, too weak, to bitter, too old, etc. I've got my cup exactly where I want it and I will not compromise. I am the dreaded woman who carries a thermos everywhere. (and, for long trips, I bring my own coffee making system.)
"And worst of all, I love it..." I feel this in my soul.
Love how James is scientific without being a scientist. More people need to be like that!
This is so much true, is becomes truer with every second. 👌🏻
Anyone can be a scientist as long as their methods are correct! I'd argue James is indeed a scientist.
@@reddish98 Better than a lot of "real" scientists these days.
Rumor has it, every time James slurps...it causes a mini sonic boom like a whip.
For some time I've used a 20oz Yeti Tumbler to take my coffee to work and avoid the sewage brew they offer for free, and it as worked wonderfully. It is a well engineered product, relatively attractive and keeps my coffee from going too cold to enjoy for hours. Now that I've been working from home, I don't need my tumbler. It's a bit big in the hand, I don't need that much coffee at once as my coffee pot is in the next room and I like drinking out of a mug. So was looking at the Ember mug and very close to purchasing it, but I've got two kids and I just could not justify the price. Then, Yeti came out with it's first attempt at a14oz insulated mug, bought one on the spot and I could not be happier. The mug itself, like the tumbler, is 18/8 stainless steel, double-wall vacuum insulated and dishwasher safe. The standard lid has one slot to sip the coffee from and keeps out about 90% of the ambient air that dramatically slows the cooling effect opposed to leaving it completely open. The temperature range where the coffee inside is at it's most enjoyable is hours, not minutes. Yeti also makes a 10oz and 24oz mug but the 14oz is perfect for me.
I imagine that a double-boiler would be a gentler heating method than microwaving and that if you included this in your test you would've found that to be the best of the reheating candidates.
I bought the Ember because James recommended it and I totally agree. I’ll never drink coffee out of an ordinary cup ever again,
Dude I would also buy one, but my mom has always had the craziest cutest mugs, it's kinda of a tradition to hand out a mug as a present, so it would be hard to drink of a plain mug like that. at work I always try to take the one with the best logo on it because F drinking off a white dead mug.
@@svampebob007 paint. the. ember.
Rishi Sunak approves ...
I like the ember thermos better, just more usable outside.
The ember mug was the best investment I did in a unnecessary gadget... like ever.. Got it at the beginning of the pandemic and I love it so much. I am a slow sipper, hence in a normal mug my coffee is cold before I even drink half of it.
In the rare occasions I visited the office since, it also enabled me to brew at home, and still have warm coffee until the end of early afternoon. In combination with a thermos, I do not even need to bring the charger. (yes, keeping in a thermos and reheating for hours is not ideal, but still tastes a lot better compared to the coffee I get at work)
To me the Ember mug makes total sense. After harvesting, processing, shipping, roasting, packaging, selling, brewing and the care and love that goes in all those steps, keeping your brew at THE right temperature seems like a logical step in our quest to have a delicious cup.
I didn't have my Ember mug for three days and I didn't realize how much I missed having it when all my hot drinks would progessively get cooler.
giving away grinders to people who cant afford one is a super sweet idea, and it really warmed my heart! the price is the main thing keeping me from getting more in depth into coffee (i use $2 espresso bricks in a cheap machine lol) i hope the people who got the grinders liked them!
I tend to brew very fruity coffee lately, which tastes like ice tea when its cold :)
To each their own
Have an Ethiopian that really tastes like blueberry with a tea like finish when it gets cold and its sooooo good.
Thought the same, I dont drink the light roasts too hot, i actually like them warm to cold better, that way the fruitiness comes out way more
@@tkbikesnc6079 yes, Ethiopian’s my favorite!
@@tkbikesnc6079 I was about to comment the same thing. Ethiopian that tastes like blueberry is insanely good.
I would have liked the extended cut with more confused James trying to make heads or tails of the bowls.
“If you’re on that bandwagon, I’m open to a peer reviewed study” 😂 I feel like this response is applicable to a lot happening right now!
I'd be interested for you to try the "Burnout Mug". It has a liner with a specially formed wax to cool the coffee to a drinkable temperature, but then as the wax freezes again, it releases heat just at the melting point (60c/140f), keeping the coffee at a drinkable temperature for hours on end. Yet another fantastic use of Phase Change cooling.
I love how James is carrying around a plugged-in and powered-up microwave.
"for now I'm open to a peer reviewed study"
For me this is gold
This rings so true 😉. Reminds me of all the conspiracies that people believe without any real evidence. Most are going off of pure hearsay. It's just sad 😢
In my experience, the best method of reheating is on the stovetop, but very slowly; similar to your reasoning for the microwave, reheating slowly on the stove maintains the flavor pretty well. This is also the best way I've found to reheat milk drinks, as well. A coffee with cream or milk will reheat well on the stove, if done so slowly. It can take 10 minutes sometimes, but it does work.
10 minutes?! I'd never wait that long!
I mean 10 minutes is about the time it takes to clean a french press by hand and fill it up again, although I'm either being really generous to the French Press or I just drag my feet cleaning the damn thing because I hate doing so. I just bought an aeropress that'll arrive soon. Hopefully I never have to clean a French Press again after that.
In the out-there spirit of the steam wand, I was sort of hoping for some perhaps less-practical, but also, less destructive formats for reheating. Specifically, I was thinking about a bain marie, a double-boiler, or even a full-blown air-tight sous-vide.
Different methods for increasingly more consistently heating delicate things to predictable temperatures, without applying a higher direct-heat to the coffee, itself (using chocolate and its likelihood of burning as my mental model for the flavour of the coffee). I suppose the double-boiler would be disqualified, if you are aiming for ~80c (what with "boil" being in its name), but I have been presuming that something akin to sous-vide would be the best shot you'd have, to return to the original-ish flavour.
Hoffman in 'Fake News' shock!
I think you need to insert a giant 'record scratch' audio fill at about the 10:06 point to fully capture the enormity of the jump!
Can you please release the part of you not knowing what's going on because you switched up the labels. Haha it would be so fun to watch😂
theyre a bit archaic but can still be found in appliance and camping areas around here. One of those submersible cup heaters, basically just a resisteive element you plug in and dunk into the coffee.
I've always heated my coffee by topping off my cup with freshly brewed coffee.
Two videos in 24 hours? Christmas has come early!
The only thing missing is a control of a fresh cup that hasn’t sat and cooled at all
Can't can't do that, since the control would from be a different batch, and would be slightly different from all the others even if reheating didn't alter the taste at all.
He’s had close to a billion control already.
Why ruin an entertaining video with logic?
That was the little bit left over that he drank, after he poured the Bowls.
Wasnt that the ember cup?
It never cooled.
I'm a coffee fiend James my average consumption is 7-20oz. cups a day. I brew a pot of coffee then decant it into a thermos. When the coffee in the thermos gets cooler I re-heat the cup of coffee for 1:30 in the microwave. Stone cold coffee at room temperature (in my case 60 F. degrees because that's what I keep my house at in the winter) requires 3:00. When the power is out, I put the coffee into a stainless-steel copper-bottomed saucepan which is heated on the gas range for 3 minutes. In the summertime when it is hot, I like to drink it cold usually in a pint glass. Ah... nectar of the gods. Great video thumbs up.
It is a rare experience to witness James make an error, and a whole other one to attempt to right it. Firstly, I'm glad to see the solution to hot coffee an hour after you make it is in fact not to re-heat it, but to just never let it get cold in the first place. The coffee-oriented thermos' that are around these days are so so good. BUT they can be SO MUCH BETTER if you do just one thing that James forgot to do. When you take the thermos out of the cupboard, before pouring hot coffee into it, pour the extra hot water into it from your kettle and wait a few minutes. (This works brilliantly for normal coffee cups on chilly mornings as well.) Pre-heating the vessel ensures your coffee doesn't cool down immediately upon pouring it in. You get a warmer cup, a longer-lasting thermos, and a notably happier day.
I've had my ember mug for about a year now. Like James, I do love it. That said, one thing I've noticed is that towards the end of the cup, say when an ounce or so is left, it tends to heat a little too aggressively. Only then does it give off that diner-stewed-flavor profile that we're all trying to avoid. Wondering if James or any other Ember users have experienced this?
Here in the Philippines, we just drink the cold coffee outside.
Because whoever drink hot coffee here in southeast asia, either its still morning or just pure mental problem.
@@NashTheGreat i drink whenever even at midnight. Idk in your country but in PH we drink coffee regardless of weather lol.

@@kira7741 Nah, iced coffee here in the PH 24/7. No fogged up glasses too, which is great.
Cold coffee outside in the Philippines = hot coffee almost everywhere else in the world 😍
Coincidentally I was just having a discussion with a friend about coffee gone cold. The trigger for that conversation was that I had found that the latest coffee I have from Square Mile actually seemed to taste better when more cooled more than I'd usually drink my coffee and still tasted good even when cold. I was finding the most interesting flavour profile was maybe when it was lukewarm. This has not been my experience with other beans and I'm wondering if this is just an indication that my brew technique was off a little with the new beans or if it is just their character. I'll try varying my grind a little and explore some more but it was surprising to find that I was deliberately drawing out my drinking time to also get some colder coffee.
We then got onto the question of whether it was odd to like iced coffee but not like a coffee that has gone cold sitting on the bench (assuming you otherwise had the same ingredients)? Should they taste significantly different?
"I'm open to a peer reviewed study" I love you man.
I actually drink my coffee if it goes cold, I don't reheat it, and I don't throw it away, it's coffee. that "magic" mug looks like something I can use, my bank account doesn't agree, cold coffee it is.
I like using double-walled mugs. I'm the kind of person who sips on coffee for about half an hour after I make it. Sure, it's a bit hot at first, but it also keeps it in a drinkable temperature range for longer than a regular mug. I'd guess it's similar to using a thermos, but it cools faster because the top is open to the air. This still isn't a reheating method, though :)
Another benefit is that double-walled mugs keep iced coffee cool. I've had ice pebbles stay frozen in my cup for over 2 hours before.
I somehow expected a "double boiler" method of some kind
I love your response "I'm open to a peer reviewed study." Really shuts people up because it's a consistent metric by which to evaluate evidence.
Zoning out and then paying attention only to hear "There's a grindr giveaway" was quite a surprise
"I need a liter of coffee."
Oh my European friend; that's my every morning.

Hey James! For me, the best way to reheat coffee would be with the milk frother. It reheats it gently and doesn't go over 70 degrees. My frother even has an adapter, which doesn't froth the coffee, only swirls it. Thanks for your video, entertaining as always!
It’s strange. I love hot coffee. I love iced coffee. I don’t like hot coffee gone cold. I’ve always just used the microwave. Always appreciate your videos, James.
James' favourite coffee temp: 54 deg Celsius
My as an intellectual: hot coffee left to cool for about 10 minutes at room temperature
If I forget some coffee leftovers laying around I just drink it cold, I like it... Good coffee tastes good either hot or cold.
I find that the coffee taste changes as it cools down, you can have different experiences drinking a cup slowly
Asian grocery stores (Chinese) often sell tea mugs with a lid. they are quite good at keeping beverages at drinking temperature for extended periods. i recommend these. .. If i don't use one my coffee often gets cold and i drink it like that and don't mind it.. perhaps i've gotten used to it :)
"...open to a peer reviewed study." - And THIS my friends is how it is done!
I think it would have been very interesting to see what reheating with the embermug would do. because this would also "let it cool fast" and "never bring it to a too high temperature"
"If you're on that bandwagon, I'm opened to a peer reviewed study"
Dear Sir. You had my interest for months, but now you have me respect!
I luv this fancy coffee channel
& the audio work is always a blessing
so calming on any of my headphones
thats why i binge watch this channel & not get over it

*when mom zips up my jacket before I play in the snow
This has me rolling on the floor :D
🤣🤣🤣🤣🤣
I just cant get over the sound of the taste testing. 😂 James, your videos are a delight!
This video is 3 years old now, but I just recently discovered this channel. I got an ember mug for Christmas from my wife and I love it when I'm working from home. I find that it can overheat the last couple sips of you aren't careful and that it will eventually make the coffee taste wierd if its been too long, regardless of volume left in the cup. On the otherhand I perpetually forget my coffee and it makes sure I can enjoy my nice coffee. Overpriced? A bit. Worth it to me? Absolutely.
I like that you used the Decent machine to steam the coffee. Deep down you KNOW it’s the best.
I have distinct memories of my mother reheating coffee in our home microwave and it tasting of buttered popcorn.
That sounds more like a microwave cleaning problem.
@@jayhom5385 😅
"Papery caramel" - sounds rather like some sort of remnant of milk steaming, no? I have to imagine that _some_ milk will get into the wand each time, as it's always turned off while still submerged, and even blowing it out afterwards likely doesn't completely clean it - especially if the wand is hot enough to make the sugars in that tiny amount of milk react in some way. Couldn't this be tested simply by steaming some water and tasting it?
Paper / cardboard flavours are a symptom of oxidisation.
my first thuoghts exatcly
I often use a drip coffee maker when I need to serve 3+ people (I use a v60 when it is just me) and I've set my coffee maker to shut off the plate immediately when done brewing (0 minutes "keep warm".) When the coffee has been sitting for a while I have used the microwave to heat it back up and have been quite satisfied, glad to see it's been the right choice!
I actually use the double-boiler method to keep my coffee warm sometimes. I drink my coffee quickly enough on a weekday morning that this usually isn't a concern for me at all. But on a Saturday or Sunday if I'm making pancakes and bacon for the family or something like that, and my hands are being kept busy and I don't have enough time (or relaxed space) to enjoy all of my coffee while it's still hot, I'll just remove the lid to my stovetop gooseneck kettle and rest my coffee cup on the opening of the kettle while I leave it at a gentle boil/simmer. The coffee stays nice and hot, doesn't reduce (like it would on the hotplate of a Mr. Coffee machine or something), and I get a perfectly hot sip any time I want one over the course of a half hour or so. (Honestly...how could a single cup of coffee last you longer than that, even if you ARE distracted and busy with other things???)
A cup in my hands wont last two minutes,lol
Coffee gone cold...that’s when I add hot milk!
Thank you for posting this! My dad brews 12 cups at a time and microwaves a mug full when he wants some throughout the day so maybe I'll buy him an Ember mug for Christmas
I love this video because I know I shouldn’t reheat my coffee, I know I try to make good coffee but some days work and college just get the hold of my life and knowing that there is an option and that it’s not “terrible” makes me feel better bc throwing it away is not an option and I don’t always want it cold. So thank you for making me feel less guilty of doing something I’m always told is wrong and makes me a terrible coffee lover
I always make more fresh hot coffee and let it warm up the cool coffee by mixing them. I also have silicon ice trays with lids where I keep frozen cubes of coffee to my strength and mix so I can cook down too hot coffee quickly without watering it down.
the juxtaposition of me watching this as my coffee gets cold...
The irony *
Ha! Yes!
If you drink coffee slowly, just put it in a thermos immediately, then pour out smaller amounts into a cup. tastes fresh and is the right temp the whole time.
Yep. I do this at work with a “looks like I’m camping” Stanley thermos. The only issue is drinking coffee when driving.
I own the Ember mug and it's just amazing. Now, I don't know if it's the placebo effect, but I've had the best results reheating on the stove at a ridiculous low heat. 2nd place goes to the microwave, where I lower the power so it takes longer. Both methods I rather go for not exceedingly hot (no thermometer) since just a little bit of extra heat renders the coffee undrinkable!
just wanted to say how refreshingly lovely your videos are, your passion shines through and it feels like you are sharing your latest projects with an old friend as opposed to an audience of 100k+. Keep it up and safe holidays James
Hey James, what about pre-heating the thermos next time? Put some boiling water inside the thermos while you are brewing and right after brewing exchange the liquids.
Does it actually do anything ? I’ve done that before... but then i thought to myself that I’d gone a bit mad 😂
@@onemanshow4116 I don't know, James is the expert here.
I've done this. It absolutely makes a difference!
Yes, helps a lot! More for the steel ones then for the glass ones (more mass). It makes sure the coffee is not cooled down suddenly while poored in and keeps it warmer for longer.
Really treating us with the uploads recently, Mr Hoffmann!
There are travel mugs that drop the temperature to 60c and hold them there for a long time using liquids that flash to steam at that temperature. I have a couple by LEXO that are fabulous. great video, I too appreciate the peer-reviewed study line.
When I need to reheat my coffee, I use a Secura brand coffee frother.
I do not use it for frothing, but discovered that it will reheat coffee to 65°. It has a small element in the bottom and the warming “wand” keeps twirling the coffee around until it is the right temperature. If I can get it into a yeti mug, I usually do not have to do this, as it keeps it hot for a very, very long time!!!
Except when you leave your Ember on the charging pad with coffee in it and come back in a few hours with tree-ring-like evaporation lines on the walls 😂
I wonder how an immersion circulator would fare considering it could precisely target a sub boiling temp and not rise above.
I suspect pretty close to an Ember
@@jameshoffmann was expecting this to be the wildcard for reheating. Get that chamber vac out 😆
"This thing is completely ridiculous and I hate how much I love it"
My new favorite line for most of the things I have
Saw the price of Ember mug in Canadian dollars. I'll make a new cup....
@@cb7172 goes right up there on the wall with his line about his hate for that really crappy espresso machine. Something like: "You are the cause of global warming, and I hate you."
I have used a 2p ounce Zojirushi "thermos" for some years, James. I brew directly into it from a Moccamaster. These guys are the BEST at holding temperatures.
Keeps it TOO hot, yes, but it is sippable all day. And, it seems to not degrade in flavor. Usually reheat it once, in a microwave.
Based on your input I may turn down my Embers (I have 5!) To 135f.
These videos are amazing, James. I'm bummed to miss the grinder giveaway. I've always wanted a decent burr grinder - but as you mentioned, they can be pricey! Much love from Colorado.
you're making me really want an Ember mug
Maybe the solution to cold coffee is brewing coffee that still tastes good after it has cooled. In my exp the morning mug begins with the best flavor before beginning to eat breakfast. Somehow for me, eating transforms the taste. Later, the last of the mug has cooled and the flavor has gone bitter and unpleasant.
Another run experiment. Thank you. I use an ice cube in a thermos also. My favorite is the Fellow Joe mug preheated a little.
Best thing I've found is either those mug heater things or the Ember mug. The Ember is more gentler but the mug heaters are cheaper... but also seem more dodgy.
