Coffee water profile

[Rlawlyes]

Does anyone adjust their water profile for making coffee? If so, do you use the same for cold brew as well as hot brew?

At work, I have had the best results with DI water off our in-house system.

RO and DI are great sources to start from, but they do need a little bit of alkalinity to help take the bite out of the coffee acridity. A bit of baking soda is effective in supplying the alkalinity and sodium. The sodium does help slightly with sweetness perception. Sorry, I don't have the dose, but its not much.

Thanks guys, I will do some experimenting.

usually when i'm drinking coffee my eye lids are barley open...so no, i don't want to calculate pH, and molar ratios at 5am.....

Agree!!

The thing to do is mix up a gallon or two of the water and just pour it into the maker when needed.

wouldn't that form salts, and wear it out quicker? unless you use a french press.....

Personally I just use filtered (we use commercial Brita to reduce Chlorine) for my morning cup, gladly we don't have any issues with hard water. Probably it's not the best solution, but it works for me and missus and well, I admit that we are not cofemaniacs.
