Frozen Water Bottles Go In The Top And Fermenters In The Bottom
The top, bottom, front, back and sides have 2 inch thick foam panels on the inside to keep the cold in.
Fours Not A Crowd
The cold air from the frozen water bottles on top circulates downward forcing the warmer air upward where the cycle repeats itself naturally.
