I have a stuck fermentation of an imperial stout that started around 1.080 and is at 1.035. I added one tablet of Beano on an attempt to reduce it at least to 1.020. Five days on I have seen zero activity at the surface of the beer on any of the last five days. Zero activity through the blowoff tube. I have read on this forum it may take a while for Beano to work. Please help set my expectations.
Other info of note: yeast is White Labs Irish ale, 5.5 gallon batch, been on carboy 3 weeks as of yesterday, last gravity reading was last Weds.
