Could I put it in my garage and see if it takes off? If it doesn't I can bring it in, but my last us-05 batch fermented way too hot with tons of esters so I'm trying to limit that. I'm also excited to try my new stir plate I made for ten bucks!
Do a search for it. There is quite a large thread on it. In a nutshell, it is slow to start fermentation. Almost everybody saw at least 24 hour lag time before it took off. But when it did, it was a vigorous fermentation.
When I rehydrated this yeast it had a much more pronounced yeasty smell and darker color than other dry yeasts I have used.
My experience was the same, slow start at almost exactly 24 hours lag time but a much longer active fermentation phase lasting almost 6 full days before the krausen started to drop. Not sure about excessive heat generation.
