Have extremely hard water where I live (25+grains!). I installed a Watts Premier Reverse Osmosis system with a mineralization cartridge. Water is as good or better than bottled and taste great. TDS on the RO water is around 30 with a PH of 7. Been working great for espresso in my Barista Express. I believe water quality does make a big difference in the taste of your coffee.
Same as you hoon, i was counting on my refrigerator water.
Happy to hear you keeping your Rancilio. I feel like you are starting to get the hang of it. You might consider adding a PIV to your machine. There is the issue of the warranty if you do. I made the decision to add one to my Gaggia Classic that is only a month old. I know it may screw up my warranty but I am willing to take that risk to have good coffee. I don't plan on getting rid of it for a while so I'm going to make it the best espresso machine I can.
Excellent test, great tip, thank you
Hi from Connecticut..👍
Can you use the TDS meter, not a refractometer, to measure and calculate extraction rate?
James Hoffmann did a nice video on this (for coffee), pure demineralized water is not the way to go, including as main source for drinking, the devil as usual is in the details (what minerals, not only how much) when below a certain level. Your tap water probably is hard, and going down that much from your filters already is impressive, going one more step would be great (and barista express filters does that), but not up to no minerals.
Thanks
Hey Hoon! So you're right in the sense that tap water is rarely good to use in espresso machines. But TDS meter as specified in the other comment doesn't measure hardness but rather how much dissolved solids/minerals your water has. Hardness is generally measured in CaCO3 (calc carbonate) and TDS doesn't isolate this mineral. But you can prob infer high TDS usually means high hardness.
Great Informative video, Next time try doing test from best to worst water for a better accurate test.
every time after each sample douche the probe clean. with the pure water. contamination will occur if you don't . worked in a lab.
First thing I did when I got my Appartemento was to purchase the right water. I’ve had bad experience using home filtered water.For americano I use boiled water, so I save the bottled water for my espresso shots. Pretty sure that this will keep my machine in good health.
Hoon, just seeing this video on Sunday morning at
What is your water machine? I live in Tucson and use a filter and it is 105. Need to do better
I would not use plain r-o water which is what the vending machines produce. That could corrode your machine. For a thread regarding this see:
That meter doesn’t tell hardness. You need to use a bwt water pitcher. You’re going to line up your machine
I got this tester and the bottle water "Arrowhead" I have been buying tested fair "Marginally Acceptable". I guess I will try a different brand of water.
My wife had one and it doesn’t work very well, I use it to check my fish tank. I use primo water with my Breville with a filter attached so I never have to worry about water quality. You can refill a 5 gallon bottle for $1.75 where I live.
Hey Hoon, what’s your opinion on lelit machines and grinders? Thank you:)
How do I see the EC?
