Three gallon plastic carboy made from a clear, stain-resistant, non-porous PET plastic that is impermeable to oxygen. Light and virtually unbreakable. Requires a racking outlet and SimpleFlo valve (#7898 and #7899, sold separately), which allows you to transfer beer or wine by draining from a spigot instead of siphoning. Use a ported closure (#7885), a drilled rubber stopper (#SD10) or a medium universal bung (#40490) to seal. See Better Bottle's How-To Tips for directions on handling the carboy.
