Fermentation Crock by Boleslawiec, 2l, 3l, 4l (0.5, 0.8, 1 Gal)

Air-Free Fermentation

Once you shred your vegetables (for best results, we recommend using quality wooden cabbage shredders) and pack them in the fermentation crock, it is very important to keep them in an air-free environment. This prevents harmful molds from forming on the brine surface. Regular pots, pickle jars and plastic containers are not as safe because their lids are not airtight.

Traditional Polish Fermentation Crock

Make authentic sauerkraut, kimchi, pickles, and other probiotic-rich fermented foods with this handcrafted Polish stoneware fermentation crock. Designed for reliable, natural fermentation, it combines traditional craftsmanship with modern functionality for consistently delicious results.

Water-Seal Airlock for Safe, Natural Fermentation

The built-in water-seal airlock creates the ideal oxygen-free environment for fermentation. Simply place the lid in the rim and fill the surrounding channel with water. The seal allows carbon dioxide produced during fermentation to escape while preventing air, dust, mold, and insects from entering.

This natural fermentation process helps preserve flavor, nutrients, and beneficial probiotics without unpleasant odors or fruit flies in your kitchen.

Includes Ceramic Fermentation Weights

Each crock comes complete with matching ceramic fermentation weights to keep vegetables fully submerged beneath the brine—an essential step for successful fermentation.

For finely shredded vegetables like sauerkraut, simply place one or two whole cabbage leaves over the shredded cabbage before adding the weights to help keep everything below the brine.

Durable Polish Stoneware

Crafted from premium glazed stoneware in Poland, these crocks feature thick ceramic walls that help maintain a stable fermentation temperature, creating the ideal conditions for rich flavor development.

The durable ceramic is fired at 1260°C (2300°F) and finished with a food-safe glaze that is:

• Lead-free

• Cadmium-free

• Non-porous

• Easy to clean

• Built to last for years

The beautiful brown glazed finish adds timeless European craftsmanship to any kitchen while serving as a functional fermentation vessel you'll enjoy for generations.
