Yeast and Fermentation / Slow Yeast?
« on: November 11, 2009, 09:05:59 PM »
I recently fermented a rye stout. The OG was about 1.065, which is what I was shooting for. I pitched my yeast and observed vigorous fermentation...but only for a couple days. The gravity was at about 1.020. I let it sit for a few more days after attempting to rouse the yeast a bit, but had no such luck. I even added more yeast and it would not drop below 1.020. It also did not carbonate very well, but it still did.
I know that my my dextrins were not too high, but I can't for the life of me figure out what happened. I've never had that problem before and haven't had it since...is there some trick to fermenting dark worts, or is this just some sort of anomaly?
