Your days of lugging heavy glass carboys around are over thanks to these plastic carboys! Our Plastic Carboys are made from 100% Virgin PET plastic, which is far more resistant to oxygen than regular plastic. They’re much lighter and safer than glass, which is good if you need to move your fermenter around the house to find the right temperature. Full carboys can be heavy and hard to maneuver and glass can break resulting in possible injury. In addition to being safer to handle, they’re more economical than glass as well. With no ribs on the sides, there’s no place for yeast and sediment to collect, making cleaning a breeze. We suggest cleaning them with an overnight PBW soak, shake, rinse, and sanitize. You’ll want to avoid vigorous scrubbing during cleaning to avoid scratches.
