I brewed today using the Imperial Loki A43 yeast. This is a kviek strain. I pitched at the very high end of 100F. The wort was very aerated with a layer of foam and an hour after pitching I've got bubbles in the airlock and a nice krausen starting to form. I'm using my new big bubbler and like being able to see what's happening.
It's sitting in the closet and reads in the mid-90's F right now. The room temp in the closet is a toasty 80-85F depending on the time of day. With my day time temps in the 110's and my HVAC keeping the house at a nice 80F the kveik yeast seem to be the way to brew here in the summer.
