I brewed Edworts Haus pale ale on Sunday as the snow was winding down we had about 3 inches of new powdery snow..
Guess what this is .
It was about 20* when I started so I wrapped the cooler in foam and put wash bucket over it .
Held 153-4* the whole hour.
Make shift wind blocker works very well as the heat moves up the side of the keg
