I live in a cabin in Northern Arizona at 7000 ft without air-condition (not needed). We have a wide temperature range outside in the summer from the high 40s at night and it can reach 90 for a short time in the afternoon. I am going to setup a recording thermometer today to see how stable the inside temp is. My questions are about making beer in the summer with the warmer temperatures and the wide range. We have some very good water for beer here and made some great beer this winter. Can I make the same beer this summer? How stable of temperature do I have to have and is there a beer that will do better at the higher temp.
