Glass & Plastic Carboys for Home Brewing
Carboys are essential fermentation vessels for brewing beer, wine, cider, and mead at home. Whether you choose a glass carboy for long-term aging or a plastic carboy (PET) for lightweight handling, both options offer reliable fermentation in a range of sizes from 3 to 7 gallons.
Glass carboys are completely non-porous, resisting oxygen exposure and scratches — ideal for primary or secondary fermentation where clarity and sanitation matter. Plastic carboys are made from food-grade PET, offering a safer, shatterproof option that’s easier to carry and clean.
Choosing the right carboy size depends on your stage of fermentation:
- 6.5- and 7-gallon carboys are best for primary fermentation of 5-gallon batches, providing headspace to contain krausen during active fermentation.
- 5-gallon carboys are ideal for secondary fermentation, minimizing excess airspace to reduce oxidation risks.
