stout fermentation pretty much stuck... why
I have a stout in the primary which has not gone below 1.030 for 2 weeks now. It's been in the primary for a total of 4 weeks. It was a fairly big beer for my AG setup, so my efficiency was pretty low at around 66%
13lb - 2 row
2.5lb - roasted barley
1.5lb - crystal 10
1lb - chocolate malt
mashed for 1 hour at 158 (probably cooled to 154 within that hour)
1lb molasses in boil
1lb dark brown sugar in boil
OG - 1.088
So I am targeting a 1.025 FG and using safeAle US-05 which has always been a fast and complete fermenter, but it just quit this time at 1.030 (65% attenuation) I've tried stirring a few times, but it won't come back to life. I have used this recipe before and always hit my FG, but I must admit I've never mashed this high as I usually am in the 150-155 range.
So is this beer done? Did my mash temp at 158 cause this crappy attenuation?
