These beautifully crafted stoneware crock pots are the essential product for pickling your vegetables and making delicious sauerkraut. We are thrilled to offer you the finest quality hermetically sealable fermentation pots available in the US Market. Made in Poland, where the highly enriched vitrified clays provide the strongest and most elegant building material for clay pottery and ceramics, these pots are made by craftsmen who have had this artform passed down to them. Purposefully designed with an airtight water-sealable cover so that you do not have to repeatedly open them to scrape off surface mold; simply pour a small amount of water into the channel on top and the cover’s design will allow gases to escape without letting oxygen in.
