Without question, the greatest invention in the history of mankind is beer. Oh, I grant you that the wheel was also a fine invention, but the wheel does not go nearly as well with pizza.
-Dave Barry
I have mine at roughly 42F, one word of caution though. When you get the thing up and running get the temp you want a then put the beer in. I made the mistake of adjusting the temp in mine and going out of town for 2 weeks , returning to frozen kegs.
