Cool Brewing Cooler for Fermenter

Control your fermentation temperatures with Cool Brewing’s simple, yet innovative, insulated fermentation bag. Fermenting your homebrew at the right temperature is one of the critical factors in making good beer. Let the temperature get too warm, and your beer will taste ‘rough’ as the soft malt and vibrant hop flavors dissapear! The Cool Brewing Bag allows the apartment brewer, those who have space constraints, or the brewer on a budget a great option to control fermentation temperature and make great beer.
Cool Brewing’s Fermentation Cooler is designed specifically to accommodate standard 30 liter fermenter. You freeze a 2 liter soda bottle with water, or similar, and place in the fermentation bag with your fermenting carboy.
The typical desired ale fermentation range is on average around 20-23 degrees C. For a typical 23L batch frozen 1 x 2-liter bottle should lower wort temperature around 2 degrees, while using 2 x 2-liter bottles will lower wort temperature around 5 degrees for 24-36 hours. Of course your exact results might vary but you can adjust the amount of ice you use as you go. The manufacturer has found they can cool the wort temperature up to around a 10-12 degree drop from ambient room temperature.
The Cool Brewing Fermentation Cooler is sealed, insulated and 100% waterproof so it will efficiently and neatly keep your temperatures in check. When you’re done, the Cool Brewing Fermentation Cooler easily folds up for storage until the next brew day!
Another advantages to brew in this cooler is can avoid light strick for beer, and avoid/reduce smell in room for spirits by connect a tube between the cooler and outside of room.
