Uh oh...the 10g Dead Guy Clone I made is at 1.026 after 3.5 weeks. I mashed at 158F per recipe guidelines. I had it in a 64F water bath for 3 weeks & witnessed vigorous fermentation not long after I pitched the Pacman yeast.
When I measured the gravity at 1.026 after 3 weeks, I stirred up the yeast in both carboys & put them in the house at 74F room temp. They have been at 74F for 5 days now & today I measured gravity again & it's still at 1.026.
However, I see a tiny bit of airlock activity, but these are in better bottles & I can't tell if that's from minor temp. swings in the house or not.
What do I do? How long do I wait before accepting that fermentation is complete & this will be a very malty sweet beer?
I need these carboys soon for dry hopping the LWPA batch. This is messing with my brew schedule.
With pacman yeast, I've had it finish as low as 1.012 or so even with a higher mash temp and cool fermentation temperatures. Do you want to try adding some dry nottingham and see if it'll give you about 8 more points of attenuation? This beer really is good at 1.016-1.018 or so.
