This 5-gallon carboy and 3-piece airlock set makes an ideal bundle for home wine, beer, or other fermented beverage making. The clear Italian glass carboy provides a 13-pound, 20x11x11.25 inch fermentation vessel while allowing you to visually monitor the process. It is coupled with a set of 3 durable 6.5-inch drilled rubber bung and airlock assemblies designed specifically to fit a carboy for venting gases during fermentation. The airlocks automatically vent CO2 at room temperature thanks to an airtight, transparent, food-grade design that also prevents oxidation. Simply insert the pre-assembled airlock pieces into the carboy's hole, fill with water, and let the fermentation magic happen while the cap traps oxygen and contains liquids. The airlocks are stronger and more transparent than other designs, enabling full visibility of the stages of fermentation. With a large, clear fermenting carboy and automatically venting airlocks made to directly fit, this bundle provides a complete setup for home brewing and fermentation projects. 5 gallon clear glass carboy with 13 lb weight capacity made in China Includes set of 3 transparent airlocks and stoppers to easily view fermentation process Airlocks automatically vent CO2 and prevent oxygen exposure during fermentation Stoppers fit most standard 5 gallon carboys and jugs Satisfaction guarantee - replace cracked or broken parts Brand Name Homebrewers Outpost
