I started AG about 10 batches ago and for the first time have started measuring the OG. Last batch started at 1.030( measured at pitch) and after 15 days got to 1.020. Now I am wondering if all my beers have been low Alc% the whole damn time. Have learned so much already been reading here for 6 hours. I feel I know where all my mistakes are, from the crush (??) to draining too fast, poor sparging disciplines. I have horribly soft water and sure that has a huge effect as well. One question, what is over sparging? I currently sparge till I get my 12 gallons, regardless of the color. Should I stop and top off with tap water then measure my OG. I am afraid now I will need DME to make up my OG. This last batch was 20lb 2 row, 2lb of xstal, 2lb of cherry smoked british, 1\2lb of roast. Either way after reading some of your imputs here, what a great tool for knowledge. I look forward to reading more post.....
