The crock manages fermentation gas passively — CO2 bubbles out through a water-filled rim, and no oxygen can enter. The jar requires you to actively burp it or attach an airlock. Both approaches work. The choice depends on batch size and how much you want to think about it at 11pm on day three.</p>
