Since Rahr is my favorite base malt, this is good to know. My ph has been off just a bit. I thought it had to be my meter or something. On other beers using other base malts it has matched my Bru water figures. You are correct, Martin is the man. I really like Rahr Pale Ale malt. My numbers on my last batch using it matched my predicted ph almost perfectly, so it may not be the same for this malt. Great info thanks!
