Ok, so last night was my first all-grain attempt. After building a mash-tun from a 7 gallon ice chest, I went with a simple recipe. 8.2 pounds of grain. My strike water was 4 gallons and it maintained 156 degree's for 30 minutes then went up to 157 then 158 - I then opened the lid for about 3 minutes and it went back down to 156 where it stayed for the rest of the 60 minutes. How is a rise in temp posible? I have a wired thermometer ran to the interior of the mash tun so I don't have to open it up. Any thoughts?
