This is my second attempt at an Alt. My first attempt had temperature control issues. I used to do the water and ice in a tub temperature control method and we had a heat wave. The yeast crashed when the fermenter got to 80F while I was at work. Had to pitch Cal Ale after attempts at restart failed. Won’t happen this time. Will be fermenting at 62F and then racking to secondary to cold condition for two weeks dropping the fermenter down a few degrees per day.
