6 Gallon PET Plastic Carboy

The 6 Gallon PET Plastic Carboy is a lightweight, ultra-durable fermentation vessel designed specifically for secondary fermentation and long-term aging of homebrew beer and wine. When full, it weighs just 42 pounds, making it easy to carry and maneuver—even in tight brewing spaces. When empty, it’s light as a feather for effortless cleaning and storage.

Crafted from food-safe, BPA-free, DEHP-free, and plasticizer-free PET material, this plastic carboy is engineered for strength and ease of use. It’s scuff-resistant, shatterproof, and virtually unbreakable—ideal for homebrewers looking for a worry-free alternative to glass fermenters.

Unlike traditional plastic fermenters, PET carboys are **taste- and odor-free**, and they’re **virtually impermeable to oxygen**, protecting your beer or wine from oxidation during aging. The interior is **non-porous, non-absorbing, and hydrophobic (non-wetting)**, which means it won’t retain flavors or colors between batches and requires no brushes to clean—just rinse and sanitize.
