Keep getting a "sweet" taste in brews.

Just seems so odd to me. Should RO water be RO water regardless where you are in the world? If so, then why is it different per person to person to add different minerals? Would t it be the same minerals for each person if they used ro water to begin with? Of course changing additives per beer styles though.

It's not different person to person, but rather different grain bills bring different amounts of acid to the mash (in general, the darker, the more acid they bring.) Since the optimal range for pH is fairly narrow, it is necessary to adjust RO water differently for different grain bills. That's why the spreadsheets are so useful.

Brew on

Op, did you get to try any of the techniques you were given here?
