Hi I'm making a stout and using the Brun Water Calculator. I have my "Pale Mail Morris Otter" base malt entered and then I entered, Black Malt, Roasted Barley, and Chocolate Malt. So on these three do I select "Roasted Malt" on the drop down instead of "Base Malt"? When I enter these three as base malts the PH goes way down to 3.5. If I select Roasted Malt the PH is right on.
