I would appreciate suggestions on lowering my FG numbers, I have been doing Three gallon extract batches. Usually OG is around 1.061 area the lowest Fg was 70% the highest was 50%. I usually do forty-five minutes boil with early addition of 3.3 lbs. of lme and 1.5 lbs of dme and 1 lb of specialty grains, I add yeast nutrients, and inject O2 to the wort. I have been using S04, S05, fermentation usually start within hours. The wort is keep between 62-70 degrees for the first two weeks, any suggestions how I can produce a lower FG? Does early addition or late addition produce more or less fermentable sugars? The info on the lme says that it is 80% fermentable, the dme dose not give the percentage of fermentability.
