Large Fermentation Jar with Airlock Lid – 1 to 5 Gallon Food-Grade Glass Crocks for Kombucha, Kimchi, Sauerkraut & Pickles

Take your fermentation game to the next level with our professional-grade fermentation jars, designed for home brewers and small food producers alike. Made from thick, lead-free, food-safe glass, these jars provide a non-reactive, odor-free environment that’s perfect for fermenting kombucha, kimchi, sauerkraut, pickles, and more.

Each jar features a built-in airlock system (or compatible grommet hole for standard airlocks) that allows CO₂ to escape while preventing oxygen and contaminants from entering—ensuring consistent, safe fermentation every time. The wide mouth opening makes it easy to add ingredients, pack vegetables, and clean thoroughly after use.
