Fermentation Jar: Medium

A fermentation jar with a wide mouth for easy filling. It sits between our Small and Large Jars in size. Each full jar yields approximately 3.75 quarts.

Sarah Kersten Studio Fermentation Jars use a waterlock seal that allows for an oxygen-free environment. 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. 

9.5" tall. 3.75 quarts.
