Our plastic fermentation carboys are made of a special PET that has negligible O2 permeability, is odorless, and does not stain or carry over flavors from one fermentation to the next. They are unbreakable, light weight, and much easier to use, wash, and sanitize than glass carboys.

Better-Bottle™ fermentation carboys are: 1) Unbreakable and tough, 2) Taste- and Odor-free, 3) Virtually impermeable to oxygen, 4) Clear and colorless, 5) Incredibly light weight, and more . . . They are made from special, scientifically tested, polyethylene terephthalate (PET) copolymer plastic that is non-absorbing, non-porous, and non-wetting (hydrophobic), so it does not do not carry over flavors from one batch of wine or beer to the next and is easy to clean and sanitize. Optional, racking adapters and valves make oxygen-free racking and dispensing simple and convenient – no siphoning is necessary. Optional closures that use O-rings to make tighter seals are more easily cleaned and sanitized that conventional stoppers. In short, Better-Bottle carboys are better.
