3 L Airlock Fermenter

$31.09 $

Use the 3 Litre Airlock Fermenter to preserve smaller batches of vegetables compared to the 5 L. Great for people making sauerkraut, kimchi, and curtido yet must use their main fridge for the cold-storage portion of the fermentation process instead of a root cellar. Also great for cucumber dill pickles, mixed vegetables pickles, and lacto-fermented beverages such as kvass, water kefir, and ginger ale. It’s ideal for families looking to preserve the harvest, economically.

Includes a rubber gasket, plug, grommet, glass disc/weight, 3-piece airlock, and 52 grams (~3 tablespoons) sea salt. Mini airlocks sold separately.
