That was the only down side I could see, but I really don't care what the SG is. To me it's just a number and it is what it is what it is and once it's said and done... I can't change it, other than add more water and here we go again with the 5 gallon carboy. Round 2 is on the wood stove right now and should be starting her boil in a few minutes. Yeeha!
