So I brewed up a Chocolate Milk Stout Sunday, and I rehydrated and pitched Winsor, my 1st time using it. Well, it took off in about 4 hours, just happily bubbling away. Pitched at about 70F, ran it down to about 64-65F, and it was still going just fine yesterday (Monday). Today, I get home and check on it, and there is NO visible activity in the airlock. Just to be sure, a few hours ago I gave the bucket a little swirl, but still nothing. Is this normal for Winsor? I did see on Danstar's website that it can finish major activity in like two days. I'm going to let it run for a week or two before I rack to secondary for the add of the cacao nibs, but I was just wondering if anyone else had seen any similar activity with this yeast.
