Make fermenting vegetables easier! This half-gallon-size glass jar includes an airlock setup which facilitates gas escaping your fermented vegetables while keeping air out. This allows you to make pickles, sauerkraut, and other fermented vegetables, fruits, condiments, and more while greatly reducing and often eliminating the threat of mold. Kit Includes: Glass jar, plastic lid fitted with a rubber grommet (BPA-free), airlock, ceramic fermentation weight, extra solid lid for storage after fermentation is complete. Container Measurements: Jar Height: 6.3 inches (9.8 inches with airlock), jar diameter: 5.5 inches, mouth diameter: 4.3 inches. Using the Fermented Vegetable Master with Fermentation Weights: Weights are ideal for whole or cut veggies. For shredded or very small pieces of cut up veggies, use multiple sets of weights, or use strips of a cabbage leaf crisscrossed over the top of the veggies and tucked down the sides of the jar. Ensure the cabbage strips are well submerged under the brine. Note that this lid size and thread pattern is not compatible with canning jar lids. Due to manufacturer source differences, the shape of the jar in the actual product may vary from the picture.
