I'm getting ready to brew a brown ale with RO water. I am planning on useing calcium carbonate. I have a few questions, do i add to both the mash and the sparge, and how much. Or i have a little pack of burton salts i could use. thanks.
From what I have read RO water has most all the minerals removed and since a balance of certain minerals help in the mashing process, depending on style of course, I would think more than just the Calcium Carbonate may help.
Burton salts are pretty high in everything but could be better than nothing!
