    I've been using BRU'n water for a long time, and its always treated my right and been very accurate. I plugged a known beer/water profile with adjustments into Brewers friend, and I get VERY different results.

    Grist, # and color's are the same. Starting water profiles (RO) are the same. Volumes are the same. Mash/Gris water ratios are the same.

    I have to double the acidulated malt additions in the recipe to get the same ph in brewers friend vs BRU'n Water.

    I know BRU'n water is right for this grain bill. What am I missing?
