We all know - temperature control throughout the brewing process is crucial. Let us help you maintain a constant temperature with a Carboy Coozie and insulate your fermenting brew from external temperature fluctuations. Designed to accommodate the most common fermenter sizes, they are constructed of a high quality insulation wrapped in ripstop nylon to create a durable product for years of insulated use. Additional features include a drawstring top, a velcro patch to allow easy checking of Krausen/fermentation (or to mount a Thermentor), and a the option to go premium and add a removable nylon strap to provide added strength as well as handles for transporting the carboy when it's time for racking.

These work great to provide an extra layer of protection, stop light from affecting brews, or the brewer who doesn't have room for a freezer but still wants to control their temperatures.
