Medium Fermentation Jar

In between our Small Fermentation Jar and our Large Fermentation Jar sits our Medium Fermentation Jar. The jars hold a little less than 4 quarts, making them an ideal jar for an enthusiastic fermenter or a family. Each full jar yields approximately 3.5 quarts of fermented goodness. The Medium jar has a wide mouth, which makes it easy to reach in.  

My fermentation jars are crafted with a waterlock seal, an ancient design which allows for an oxygen-free environment— the gold standard of vegetable fermentation. To use, prepare and pack vegetables inside the jar, then fill the channel at the jar’s mouth with water. Once the lid is placed into the water, fermentation begins, creating CO2, which in turn pushes oxygen out of the seal and maintains an oxygen-free ferment. 

Our medium jars measure 9.5 inches x 9 inches. 

Jars come in four of our studio glazes; read more about our glazes on our Glazes + Materials page. 

Each jar comes with a set of stoneware weights for Fermentation.
