So Sunday I brewed an IPA and pitched a packet of US-05. Starting gravity was 1.063. I don't typically rehydrate and have ha excellent results. So like the others I just sprinkled on top. Pitching temp was probably around 62. There have been no visible signs of fermentation. When I looked at the beer it looks like its done fermenting but there is no Krausen at all. Refractometer says its still 1.063. So I'm wondering if the yeast is dead, I killed it, and should I repitch or rouse it somehow. Yeas was purchased from my LHBS and well within the exp date.
