So first of all I finaly got my membership paid. This is the best homebrew forum, and I am glad to be part of it. Second a question about sparging. I partial mash and use about 4 lbs. of grain and 1.25 quarts of water per lb. for the mash. When I sparge i top up the cooler with the recomended amount by beersmith, which is usually around half of the original volume. After adding the first and second run off to my kettle I top up with water for a full boil of 6.5 gallons. Should I sparge the top up water for the brewpot through the grains, or am I on the right track already.
