These 7.9-gallon plastic homebrew fermenters are great for homebrewers who want to make beer, mead, wine, or kombucha at home. The set comes with everything you need, including lids, airlocks, and spigots. The fermenters are made of polypropylene, which is less porous and smoother than other materials, making them easy to clean. They're a great addition to any home brewing setup.
