I am having a problem with a stuck fermentation.
I made a really big RIS, 1.120 og about 2 months ago. I made a lower gravity beer (1.057) to get a really nice yeast cake to rack onto and everything was fine. Fermentation started really fast and vigorous. It sat on the yeast for a month to let the yeast do all they could to clean up the beer.
When I racked to the secondary, I took a gravity and it only came down to 1.040. I got 2 qts. of fresh yeast from a local brewery right out of their tanks to pitch into the secondary to see if that helps. Very little airlock activity since. I racked the beer off of the yeast after another month and took another gravity, still 1.040
Do you think the yeast just can't take the alcohol and it is done? Both times, the yeast was 1056. I am planing on letting the beer age off the yeast another 6 months so I am in no hurry. What should I do? Something, nothing, I don't know.
It is sitting in my basement, and it holds a pretty constant 63-64*. I think that is all the pertinent info.
