fermentation jars

Fermentation jars are specially designed containers used to preserve foods like vegetables, kimchi, or sauerkraut through natural fermentation. They typically feature an airtight seal to create an anaerobic environment, which encourages beneficial bacteria to convert natural sugars into acids, flavor, and carbonation. Many include a water-lock or airlock system that allows gases to escape without letting air or contaminants in. This process enhances flavor, preserves the food, and can add probiotics for health benefits. Fermentation jars come in various sizes and materials, such as glass or ceramic, making them suitable for home fermentation projects.
