5 Gallon PET Plastic Carboy

The 5 Gallon PET Plastic Carboy is a lightweight, oxygen-resistant fermentation vessel that’s ideal for secondary fermentation and long-term aging of homebrew beer or wine. Weighing only 42 pounds when full, it’s easy to handle, transport, and clean—perfect for homebrewers of all experience levels.

Made from BPA-free, DEHP-free, plasticizer-free food-grade PET plastic, this plastic carboy is designed for performance and peace of mind. Its scuff-resistant and impact-resistant body makes it a safer and more manageable alternative to glass carboys, especially in tight brewing spaces or when moving full vessels.

Unlike standard plastic fermenters, PET carboys are **non-porous, non-absorbing, and hydrophobic**, meaning they won’t retain flavors or odors between batches. The smooth interior surface is easy to sanitize—no need for brushes—and prevents cross-contamination from one brew to the next.
