This simple food fermentation kit is the ideal choice for small batches as it requires very little brine to fill the jar and submerge your vegetables. Includes a 1L (33.8 oz) jar with flip top lid, two stoppers (one with hole and one solid), and a 3-piece airlock. Install the airlock during fermentation so gas can escape, and when fermentation is complete, replace it with the solid stopper to store your pickled vegetables.
