So I brewed an American IPA yesterday and pitched wyeast 1968. I mistakenly pitched the yeast at a high temp. My thermometer said my wort was down to 72 degrees before I transferred to my fermenter. But when I looked at the fermometer, there was no temp that was registered (it goes up to 78 degrees) so I assume that it was much higher.
4 hours later, a really dense cake had formed an inch or two below the surface with no other real visible activity. At that point the temp had hit around 78 degrees on the fermometer. See the attached photo for a visual. This morning (18 hours later), the cake has dispersed and there is a light krausen on top with not much bubbling activity. The temp is now at 66 degrees (I threw some wet t-shirts around it over night to cool).
From what I understand, wyeast 1968 is supposed to have vigorous activity so I'm a bit concerned. I don't think the wort was above 90 degrees when it was pitched, but I can't be sure. Did I kill my strain?
One other concern I had was the strain itself. When I pitched, it was half liquid and half paste. I had to push it out like toothpaste to get it in the fermenter. From what I've read it seems that's okay, but I've never experienced a strain that did that.
