If you're looking for quality homebrew supplies at a reasonable price, you've come to the right place. This 6 gallon PET carboy is the perfect piece of equipment for homebrewers making medium-large sized batches of brew. Polyurethane terephthalate (PET) is far more resistant to oxygen than regular plastic, making it the ultimate protection for your beer during fermentation. The plastic construction also protects against the possibility of breakage, and if you clean after use, the carboy should last for many brews to come. In stock and ready to ship. Features: Made from polyurethane terephthalate (PET). 6 gallon capacity. Used during fermentation.
