I'm making a big BSDA (based on Jamil's recipe). He mentions in Brewing Classic Styles to mash a bit hotter if adding sugar, so I did that (153.5 or so). Ended up at 1.108, including about 9% sugar. http://hopville.com/recipe/1491021/belgian-dark-strong-ale-recipes/belgian-strong-dark-ale After a few days, I ramped from 68 to 72 over about a week. It was at 1.067 after 4 days. Yesterday, 11 days in, it was at 1.047. It was going very strong for many days, but now the krausen has fallen and it is down to maybe 10 bubbles/minute. It really looks to be quitting. I think I lost a fair amount of yeast in blowoff, but I did pitch a 2L starter that was on a stir plate. Still probably under-pitching by a bit, but close for sure. I'm hoping to get this under 1.030, and under 1.025 would be even better. I just raised it to 73.2, but I'm a bit nervous. Does 530 have a long tail to finish up? Should I consider adding more heat? Repitching an active yeast culture, either 530 or maybe 001? Other ideas? I'm usually pretty patient, but I've got a feeling I'm in trouble here. Advice and experiences would be nice. This is my first experience with this yeast.
