Fermentation Jar: Medium

The Medium Fermentation Jar sits in between the Small Fermentation Jar and the Large Fermentation Jar. The Medium Jar has a wide mouth, which reaching in and filling easy. Each full jar yields approximately 3.5 quarts of fermented goodness, making it an ideal jar for an enthusiastic fermenter. 

Sarah Kersten Studio Fermentation Jars are crafted with a waterlock seal, which is an ancient design that allows for an oxygen-free environment— the gold standard of fermentation. 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.
