Brewing an Ale using US05. Is there any off taste created if fermented too cold or is the only trouble slow/stuck fermentation? I brew in the garage and days have been 51-65F and nights in the 30's. It is still bubbling away although very slow (1 bubble every 45sec). Been going for 14 days and kraeusen is still very thick without even beginning to fall. I realize due to temp it will be slow going, but will/could there be off flavors because of the cold temp. OG 1.069. Was a 6 gallon batch with 3lb DME, 6.6lb LME and 1lb cane sugar (plane table sugar).
