The Wilma Fermentation Jar is ideal for the beginning fermenter, apartment dweller, or small-batch experimenter. Crafted with a waterlock seal, an ancient design that allows for an oxygen-free environment, this lidded crock makes whipping up a quick batch of fermented goodness a breeze.

• Size: 7"H | Yield: Approx. 2 quarts
• Material: Glazed Ceramic
• Care Instructions: Hand wash recommended.
• Use Instructions: To use, prepare and pack vegetables inside the jar, put the lid in place, then fill the channel at the jar’s mouth with water. Once the lid is sealed, fermentation begins, creating CO2, which in turn pushes oxygen out of the seal and maintains an oxygen-free ferment. 

• Each jar comes with a set of stoneware weights for fermentation.
