Hi Lance! Love your latte art videos -- they taught me what a real world class could not! About water... If I can't taste a material difference between "good" water (I've tried third wave water) and my tap water, is it still possible that I will taste the difference in pourovers made with these two?

Haven’t tried distilled with replacement. Even before I got super into coffee and was just doing French press though, I found using brita filtered water made a massive difference to taste. Obviously brita leaves behind plenty of dissolved solids but where I live the water is crazy hard so the brita takes it down to a more normal level and yields much much better results. May get some ph test strips and see if there’s a marked difference between brita and tap coffee for me. I already had the brita cuz my tap has off tastes to me just as water anyway, but I wonder how much of the taste difference is those same off tastes I dislike in the plain water versus buffering impacting the acidity

@dcuccia2 жыл бұрын
I'm new to coffee science, but I'm a little surprised how little is known by now. In the beer brewing industry, water chemistry is crucial. Perhaps that's the answer-extraction of sugars and flavors depends enormously on pH and residual alkalinity (primarily because the enzymes require it), wheras it sounds like in coffee brewing it's perhaps a secondary effect. Would love to learn/read more about the acidity-dependent complexes that change extraction yield, and *especially* if there is a way with pH to enhance the fast-extracting coffee flavor components preferentially over the slower ones (which people blame for immersion vs percolation taste profile differences, e.g.).

At 3:42. The pH scale is Acidic to Basic, not Alkaline. Also, a buffer doesn't necessarily "neutralize" an acid. If that were the case the pH would always be 7, the neutrality point.

I think I am lucky that I have soft (but very tasty to me) tap water with only a small amount of carbonates, 28mg CaCO3/l. The magnesium level is low, only 1 mg/l, so maybe I should try adding some.

So this really dispelled what I thought re: lighter roast = more acidity, darker roast = less acidity. I have a friend who loves Bonsoy. He prefers my dark roast (I';m a roaster) and part of that is because the Bonsoy splits less in the dark roast compared to my medium roast. I understood that it was acidity that caused the splitting, but perhaps it is some other factor. I do also note the bicarb-Bonsoy trick which as I understand is a base and essentially a buffer - so I guess I'm confused as to what this means.

My well water is quite soft and has a PH of 9.4. It also has high alkalinity. If I add an acid to bring the water down to neutral the water will revert back to 9.4 within 12 hours. In your opinion would I get a more flavorful cup if I dropped the PH to 7 before brewing?

I like to try different things when I find them but I still have a hard time knowing when it will or won't make good espresso, even when I think I've dialed it in as best I can. I like a good filter brew, this is just something I don't understand.

Thing is not all coffees will ever be acceptable/tolerable for espresso. Depending on origin, altitude, processing method, etc. some just won't be suitable regardless of changes made.

Good stuff… nerdy stuff, but great. Keep spreading the knowledge. It’s surprising difficult to get excellent drinking water when you live in a metropolitan area. I mostly drink RO water (reverses osmosis filtered) at home, because it’s a good way to remove all the toxic stuff that the city adds to it, but RO is also bad because it removes all the good stuff. I need to get minerals somewhere else in your diet. I’ve tried to remineralize my drinking water different ways but actually got headaches from doing that. We need people to study this more - for great coffee, but also just for great drinking water.

So the Buffer is the Total Alkalinity of the water, which acts as a stabilizer for the PH of the water. So if your buffer is too high or too low it can pull/mute/cancel out the acidity of the coffee? is that right? If only someone had a simple solution for this... It makes sense when I am dealing with my pool, but for coffee it's a big more confusing...
