# Best Fermentation Weights Source: https://fermentnest.com/best/best-fermentation-weights Updated: 2026-10-20 Publisher: Ferment Nest. Our score is an editorial rating out of 10 (fit 35%, features 25%, build 20%, value 20%), not a customer rating. Method: https://fermentnest.com/how-we-research#our-score Weights hold the vegetables under brine, which is where fermentation goes right and mold does not. Between products the differences are real: glass discs versus ceramic stones, plain tops versus notched handles, and diameter tolerances that either fit your jar mouth or sit crooked in it. Some are heavy enough to hold a springy cabbage down, others ride up once gas builds. A weight that traps one leaf above the line defeats its purpose. We checked actual mass and diameter against common wide-mouth and regular-mouth jars, then looked at how easy each one is to lift out of a full jar with wet hands. Handles and finger notches matter more than they sound. Glass discs suit most quart and half gallon ferments; heavier ceramic stones earn their price in gallon jars and crocks, where a light disc simply floats off the vegetables. ## Picks ### 1.
