Sign up ×  I'm attempting to brew a high gravity stout, OG 1088.
Its been in the primary for two weeks. I assumed it had
completed fermentation since it feremented extremely vigorously,
so much so I had to use a blowoff tube (for a bucket fermenter).
Once that calmed down I replaced with bubbler and it went
consistently for over a week. I checked the gravity today and it
is between 1032-1034, which is still rather high. Visually it
appears that fermentation has complete. I used Wyeast NB
NeoBritannia 1945, and think b/c of the high gravity it is just
spent. I have another package of this available should I
consider adding this fresh yeast to it? What kind of results can
I expect if I add another entire smack pack of yeast?

initially? If not, you seriously underpitched for a beer of that
gravity. If you want to try adding more yeast, keep in mind that
it takes a LOT of yeast to restart a stuck fermentation. 2-3 qt.
of yeast slurry is what's usua
