I just brewed this clone about 1 week ago. Used 3 pkgs WYeast 1099, Whitbread. No starter. Mashed at 149 F. Twelve gal batch.
OG was 1.086. Started fermentation at 70 F. It took off like crazy. Raised the temp to 74 as per the clone magazine suggested.
After a few days the krausen dropped big time, and my gravity has been holding steady at 1.031 Beersmith says it should have a FG of 1.020.
Any suggestions why this beer is not fermenting down to it's suggested FG?
I brewed this once before and it finished at 1.036, I only used 2 pkgs of yeast on that brew.
The only thing I can think of is I didn't pitch enough yeast for the gravity of the wort.
