Introduction music:- Drink Beer (Till The Day That I Die) by Dazie Mae
For all those asking about the intro song....The original song could come back! The intro clearly needs to be shorter though. I have spent some hours looking for an intro for the 5 seconds.
I have narrowed it down to five and now need to polish each one, including a cut of the original.
Then I will make a short video featuring all 5 with a voting section.
Let the viewers decide. It will be released very soon!
David Heath Homebrew Ah. But I like the original!
It is coming back, just in a shorter form :)
Your not a big enough chanel to ditch such a classy intro. Its super cool, were your current subscribers wont care too much cus their hooked, but new potential subscribers love the polish!
Haha, thanks John.
Ahh. I’ve just received my external filter from BacBrewing for my GF30. That means I no longer need the original hop-filter, and therefor I can whirlpool as David is showing in this video. I didn’t know the whirlpool wouldn’t work that well with false bottom. This was very enlightening! This mean, that - perhaps - the external filter was a good idea. 😎👍🏻
Thanks, David.
All you really need is a false bottom but having an external filter is not going to hurt at all :)
I personally whirlpool 3 x times on a GF brewday, between 2-2.5 mins each time, 1= pre boil, 2 = post boil, 3 = Cooled wort in FV before pitching the yeast, seems to work well as i am regularly getting above the numbers in a given recipe, only by a point or two but its better than being below the numbers each time...nice video David, thanks for sharing...
Great to hear Gary :) Being a point or two above target is perfectly fine :)
To all those that miss the intro song:- It is a public domain tune by ”Dazie Mae” called ”Drink beer till the day that I die”. I had complaints from people about the song and the length of the intro.
It does feel a little sad to change it but I've had the same intro for years and a change felt it order anyway :)
David Heath end of an era 😢
Frequently sung when brewing - great work as always David
love the old intro song but really the video content is what really matters :)
It was your trademark. We just need to get used with this I guess.. :(
It was 20 seconds I always skipped.
Your material is awesome as I’m just getting into all grain at home on a robobrew v3. I much prefer the shorter intro as well, keep up the great videos!!!
Great to hear :) Thanks for your feedback:)
Thank you David for the new video and the new format. I will miss the music but the format is nice 😀
A few days ago I used the false botton (adquired in Aliexpress) for the first time and the result was very positive. I taked care with the depth and speed of paddle during whirlpool. however, I think it would be better if it were subject more stable, perhaps with a rod or a silicone ring. I think the whirlpool is more effective and comfortable to do with the new false bottom and of course the pump works much better.
Congratulations for the Video and I repeat my thanks 👍🏼
Great to hear all round there Fernando. Good to hear that the false bottom is working well for you also. To me it should have been standard but it is a cheap upgrade anyway ! You can download the tune for free, It is a public domain tune by ”Dazie Mae” called ”Drink beer till the day that I die”. I had complaints from people about the song and the length of the intro.
It does feel a little sad to change it but I've had the same intro for years and a change felt it order anyway :)
Great stuff David I need to buy one of those whirlpool tools as I still stir mine manually.However like you I clamp my filter on as it was coming off every brew and causing me big problems at the chilling stage.
Yes much more effective with a drill...just watch the speed and distance :)
Looking forward in using the whirlpool drill, bought it a while back together with the temperature flow thingy from grainfather. haven't had a whole lot of time to brew lately, but Easter and such should give me some time to have fun with it soon
Both good tools for sure :)
There's a great Dazie Mae song which would make a nice musical accompaniment to that new intro 😋
Do tell Harvey :)
Interesting Vid David, struggling to find that false bottom in the UK, i shall keep seeking though as it looks like a useful addition to the system, with the hopeful negation of a bike pump in my brewing kit LOL! Although I have to say the bike pump works to clear a blocked filter if your not too vigorous!
It sure does Matt. This does improve the flow nicely without effort. Hopefully stock will return soon.
Thank You from Phoenix Arizona ;
🍻🍻🍻Much appreciated 🍻🍻🍻
Hi David one comment on aeration in the GF conical fermenter; watch out for the sampling spigot if you get too low.
Oh for sure. Never go to deep there either!
New intro eh? Looks good and is short. Very nice!
🍻🍻🍻Much appreciated 🍻🍻🍻
Hi David. Sorry to see your trademark intro go by the wayside. I always enjoy your videos and the intro was a relaxing mood setter, just as the practice of this hobby should be. Change is not always better. In this instance my definition of " old fashioned " is " tried and proven "
The song could come back! The intro clearly needs to be shorter though. I have spent some hours looking for an intro for the 5 seconds.
I have narrowed it down to five and now need to polish each one, including a cut of the original.

Ian Jones I agree. I can even get movement of the false bottom when the boil is happening
Hmm odd. I wonder if it is down to different sizes of the GF and the False bottom itself? If I had this then I would probably add something like silicone to it to get the fit better. I should think that would be easy to obtain.
I also saw this lifting happen during my boil. I noticed that David uses an "eyelit" in the middle of the false bottom, mine didn't come with one. I am just wondering if this helps with giving the plate some "weight"? I was thinking too of using silicone but I guess this would be quite hard to source...but will try and source it, if I find anything I will let you know :)
I wonder if the difference in false bottoms is different gen models mine is of the gen2 and looks like gen3 is being used in video. Possibly they have upgraded the metal thickness / weight
Yes it seems most lack the eyelet. You could find something to weigh it down with. Perhaps fixed to the legs underneath, though some have told me the silicone ring works just fine. Clearly FB and GF sizes do vary a little. Some are finding it a very snug fit and some not snug at all. Mine seems in the middle of the two.
Could be, though I think there is small variations in the sizing of both the FB and GF models. Most likely different factories used for both over time.
Hi @davidheathhomebrew! Question: Have you had any experience with the whirlpool arm produced by GF for the G40?
Hi, Actually this is something that I am yet to try 🍻🍻
soooooooo glad that drink beer song has gone from the start lol hope im not the only one, sorry david it was the only this i hated out of everything you do for us :p
Haha no problem, It was clear that it was too long an intro. I will be releasing a quick video over the weekend where people can vote for the new 5 second intro music. It will have 5 choices. One is a small part of the old song. Please vote and make your mark :)
Last weekend I experimented with using the grain basket as a hop spider but that didn't work at all. The boil was nowhere near as vigorous as usual, the bottom of the basket didn't stay put so the hops all got away and then they got stuck on the outside of the basket. I'm not doing that again.
Yeah it works ok with small batches on the European version but little else. It works well on the US though apparently.
I like the new intro. Perhaps a little jingle to go with it, then it’s a 10/10!
Erlend Grønbeck Hmm, thanks for the feedback:)
Should you whirlpool at a certain temp or can you start the whirlpool immediatly after flame off? how long should I whilpool for? Thanks
Start the wp after flame out. 5 mins is enough if you are using a drill.
If you fancy another tune. I know your name's not Harry, but 'Mash it up Harry' by Ian Dury would work.
Haha, not a bad idea :)
Btw, nice intro . Use off the paddle ; after boiling and before pitching the yeast OK .
Thank you. Yes. Wp after the boil and the last hops are in. :)
Hi David. Is it an issue that the areation paddle has a gap on the rod where that flat paddle goes through it? Doesn't look clean to me and looks like it should be welded all the way up. Cheers for all the great info.
It could be if you do not clean it properly but its easily done.
Hi David, would you whirlpool before throwing in the immersion copper cooler, or after?
Before usually. Unless it is a large system with plenty of room in the middle of the cool to whirlpool in. Hope this helps :)
@@DavidHeathHomebrew It sure does. Thanks again.
Great :)
Hi David! I'm planning on reducing the size of Brewzilla 65L false bottom for my Klarstein Brauheld Pro 35L. Do you still recommend whirlpooling with false bottom or do you think the boiling wort itself is enough to gain all the hop oils and other goods necessary? Is it necessary to whirlpool flame out hop additions? My main goal would be to use the pump with hop heavy brews without stucking and I hope that false bottom is the way to go. I'm going to splice 6x8mm silicone hose around the false bottom to get a snug fit after cutting the plate to a smaller size.
Top content and as always we highly appreciate your contribution to the homebrew community! Kippis from Finland!
Thank you. After much testing I have stopped using a wp when using a false bottom. It is not needed :) Glad you are enjoying my content, I have much planned :)
I know you use this method for aeration. In your experience is that enough to achieve the desire amount of oxygen in the wort?
Hi Carlos, I use to use pure oxygen. I cannot say there is much difference all told.
As usual, good video but it leaves me wondering. During the chilling process, how long and/or often do you suggest whirlpooling?
The order is add last hops/end boil....whirlpool and let it stand 10-15 mins..chill. I whirlpool for 3-5 mins with a drill and paddle. Hope this answers you question but if not then let me know.
I have never had any success with whirlpooling. It whirlpool OK but I have never been sure why I have done it. On the very few occaisions that I have used pellet hops there was still hop mud all over the bottom of the GF. I have experience with vortex separation of solids from fluids. In my case the fluid was air and the vortex was formed around the shape of the vessel. Modern Vacuum Cleaners have the same principal. In the case of the GF Paddle, it rotates the fluid and forms a cone shape within it. Theoretically then as the rotation of the fluid slows the hop depis falls to the center of the induced cone. I have never felt like waiting the VERY long time for the rotation to stop and the debris fall to the bottom. After an hour one can still determine rotation.
The problem is also that with modern vacuum packed dried hops they also have a high non-flower component (dust).
You just need the solids to drop out. Cone is not required and really needs a larger brewing system to be seen.
The Cone shape is characteristic of a vortex. It is a combination of circular momentum and gravity. Momentum is always conserved so the outer parts of the vortex rotate slower than the inner. The dust separating cyclone as on a modern vacuum cleaner has a physical cone, sometimes multiple cones of differing profile so the the particle size/mass range is greater. In our case the inner part of the vortex pulls the particles down to the centre where they eventuall lose velocity and gravity takes over. The outer part of the vortex is influenced by the enclosing body and simply rotating at a slower velocity attatched to the vessel wall and the particles drop out of suspension.
I think the use of the term Whirlpool the Hops is an Urban Myth when all it is doing is mixing them into the wort. I saw a CZcams video demonstrating the principle and large fluffy particles did indeed accumulate near the center of the vessel but Hop Pellets are fine compressed dust.
I have whirlpooled and I have not whirlpooled and the difference in the result was minimal.
The device is a good Aerator mind you.
I think it is important that people judge it for themselves. Times have changed and the use of the whirlpool is still common. I personally find that it aids in reducing fv trub and gives clarity a nice head start.
I bought the GF whirlpool paddle and a false bottom from a supplier in Norway. The false bottom is very light in weight and when I whirlpool it lifts up from the GF base and this disrupts the hops and they slip behind and end up on the base of the GF. I need to find something that weighs the false bottom down.
I am using the same equipment Ian, it is about the method as shown in the video :) I made this video so that people can try it out and learn how to whirlpool with confidence. It just takes some pointers and a little practise :)
I am still looking for a supplier of the false bottom which ships to Germany. If you could tell me yours, I could contact them. Thx
I also bought the false bottom from aliexpress and it lifted up in two consecutive batches without even doing whirlpool
@@dominiks.2949 Look at aliexpress
Where I got mine in Norway is out of stock right now. Seems all are for now.
What size is the SS hose clamp?
Sadly I do not know. I've had it for year's and it is unmarked.
Buenos días Maestro, soy de Argentina, estoy apunto de hacer su modelo y lo que necesito urgente saber que medidas de paletas puedo hacerla? Mi olla tiene un diámetro de 40cm . Me ayuda que medida de paleta le puedo hacer? Saludos
Hola, muchas gracias por tu mensaje. No entiendo español, así que tengo que traducir pero tu mensaje no tiene sentido. ¿Podría preguntar en inglés? Espero que pueda entender qué es lo que está preguntando.
@@DavidHeathHomebrew Hello Master, the diameter of my boiling pot is 40cm. What proportion or measure could the palette be in order to make a good whripool? Greetings, I await your response.
Hi, I hope I understood this correctly. It is not just about the size, it is also about speed. Using a drill with a stainless steel paddle or stirrer we obtain very good results
@@DavidHeathHomebrew Hello teacher. The stainless tube is egg or solid and I also wanted to know what size the spatula could be because my pot is 40 cm in diameter.
The size is not very important, as long as it fits 🍻
I'm going to order a Brew Monk (robobrew) soon to brew my very first beer with and saw it's also an option to add a whirlpool arm that connects to the pump. Would that also be sufficient and worth the extra 20 euro? Another question. The brew monk has a capacity to make 30L, so if I'd brew the maximum amount, how big of a fermenter do I need for the primary? I already have 3 glass 15L carboys and some 5L ones that I use for brewing mead and could potentially use for the secondary. Mead doesn't foam much, but don't know what to expect with beer.
I'm loving your channel btw! It has been very informative.
The brewmonk and robobrew are two different systems but are similar in ways. Ive not tried this attachment but think a drill will be more effective.
No oxydation possible ? …
No. Hot side aeration is not an issue for small batch brewing.
Thanks a lot for the false bottom suggestion and whirlpool guide David! Unfortunately my false bottom is just too wayward (ahem...), even after practicing in water. So I made a mod to it, test and info link from here:
czcams.com/video/rRB2rwpMpps/video.html
Works well with water, next brew will be the true test.
Great, I am a little concerned that this was needed though.
@@DavidHeathHomebrew Checked the false bottom filter I have, it weights about 300g, not sure if that's similar to yours? Seems reasonable quality, but definitely wouldn't stay put. Happy to report that the mod worked a treat in 15L of boiled wort during the brew-day. A good assertive whirlpool with no issues!
New shorter intro to teh video without the music alert, lol
You prefer it? Not many have mentioned it but some have...so I checked out the general advice online and it seems 5 seconds is what people suggest. I never really thought much about it really before.
I prefer the new intro. Love the channel.
Chris Sherwood Great, thanks for the feedback:)
What was/is the music you use as the introduction to all your videos please David?
It is a public domain tune by ”Dazie Mae” called ”Drink beer till the day that I die”. Feels a little sad to change it but I've had the same intro for years.
Hi David, nice video again, thanks! I acquired the filter a couple of days ago and did the test with water. But with the drill and paddle in a slightly higher rate it was very easy to flip the filter. So a tip for everyone: try it first with water so you can check at what speed it stays on the bottom. You can check my video here: m.czcams.com/video/VrQSKKkp2Ek/video.html
Awesome. Yes the water test is the way forward. Distance and drill speed are key. Drill power varies massively. Great to see you also showed a video :)
