I normally batch sparge and noticed that when setting up options for the sparge there is a box that you can check that states that you drain the mash tun before sparging (isn’t that how you batch sparge?) that when checked reduces the actual amount of sparge water by a gallon.
Of course I havent checked this box in the past and have always drained before adding sparge water and ended up with extra water in the tun after I reached my pre boil amount. I have always wondered why?
Should I check the box and go with less water? Any of you who use Brew Smith and Batch Sparge how is your potions set up?
