Best Vegetable Fermentation Presses and Weights

Anything above the brine line is where trouble starts: floating cabbage dries out, catches surface mould and turns a good jar into a doubtful one. A press or weight holds vegetables down so the ferment stays anaerobic without daily fussing. Options include plain glass discs, domed glass weights, ceramic follower plates, and spring-loaded inserts that push against the lid. They differ in mass, how well they fit the jar shoulder, and whether they leave a gap around the edge. We compared fit across common jar mouths, cleaning around grooves and handles, and whether each design still worked as the vegetable bed shrank. Glass weights are the safe default for wide-mouth jars and most vegetables. Spring presses suit chopped ferments that keep floating up, since they follow the bed down. Ceramic followers belong in crocks rather than jars, and the smallest weights are worth buying in a set if you run several jars at once.
