I brew with reverse osmosis water that I bring home in my no-chill cube. This time my cube must have had a little StarSan residue in it, so the water foams a little when shaken. Since StarSan is an acid, and I'm getting ready to brew an oatmeal stout, there is the potential for too low pH. I'm wondering if I should add something to bring the pH up a little, and neutralize the acid of the StarSan.
If anyone has any advice on this, it would be much appreciated.
