Review on 🍺 Optimized Home Brewing Fermentation Cooler - Enhanced Beer Temperature Control for Carboys. Versatile for Kegs and Corny Keg. Insulated Fermenter Chamber with Fermenting Brewing Bag. Cool Brewing Fermentation Cooler 2.0+ by Marcel Snoddy

Background: I saw this article on Revain while looking for some specific homebrew gear about a year ago and have bookmarked it in case I ever need it. Fast forward to last week (9/20/19). I brewed beer (a clone of Pliny the Elder) for friends. I usually wander around in my basement TV room, where the temperature is 4 degrees cooler than the rest of the house. However, my son was there and left the halogen lights on all night. Halogen lamps generate a lot of heat. The room was warm and checking the fermentation temperature after about 18 hours showed 81F. I had to take 2 kegs out of my fridge to cool down the fermentation but needed a solution to move forward. Then I remembered the Cool Brewing Bag. Current: Due to the many great reviews I ordered immediately. Arrived in 2 days as usual. I immediately put my fermented beer, which was at 63F, into a bag of (1) frozen 2L. I was amazed that 1 frozen 2L that I changed daily could keep my beer at 64F. My cellar is 70F and the Cool Brewing Bag stayed at 64F with no problem. I just took the beer out of the bag to heat it to 70F to complete the fermentation and there was some condensation in the bag which was wiped off and dried. Over night. Light! Using it will definitely be part of my routine now that I no longer have to rely on a cool corner of the house for the ideal temperature. temperature controlled freezer, but it's MUCH simpler.
