Fermentation lids for Plastia jars 11cm, 4 pcs., complete with flexible weight.

Suitable for jars with an inner neck diameter of 70mm or a standard screw lid with a size of 82mm.

Provides an airtight seal while allowing carbon dioxide to escape during the fermentation process. This creates optimal fermentation conditions, allowing you to make crispy pickles, aromatic kimchi, sauerkraut, or homemade, lightly sparkling beverages.

Made from food-grade plastic (PP – polypropylene) and contain approximately 15-20% coffee grounds.

The cap set includes:

Fermentation caps: Plastic caps with an integrated one-way valve that automatically releases carbon dioxide produced during fermentation while preventing air from entering the jar.

Pressure inserts (weight): A flexible insert designed to hold the products being fermented by the pestle below the surface of the brine, thus protecting them from mold formation. The insert is light and flexible and is suitable not for pressing but for fixing the vegetables in the liquid.

The pressure inserts are made of food-grade plastic and are designed to fit inside the jar, ensuring that the contents remain fully submerged, which is critical for successful fermentation.
