Fermentation jar 1 L GEFU NATIVO G-15810, glass jar with airlock lid for pickling and lacto-fermentation

GEFU NATIVO G-15810 is a 1-litre fermentation jar made of clear glass with a fitted lid that incorporates an airlock mechanism. Designed for home pickling and lacto-fermentation, the jar provides a compact, countertop-friendly solution for preparing and storing small batches of fermented vegetables, sauerkraut, kimchi and similar products. The glass construction allows visual control of the fermentation process, while the airlock lid vents fermentation gases and limits exposure to airborne contaminants.

Advantages

The jar combines durable glass with a purpose-built lid that channels gas release through the airlock to reduce the risk of overflow and mould contamination. Its 1-litre capacity is suitable for trial batches or for households with limited storage space. The transparent body makes it easy to monitor bubbles, sediment and colour changes during fermentation. The lid seals the jar while allowing CO2 to escape, supporting an anaerobic environment beneficial for lactic acid bacteria.

Suitable for

• Small-batch vegetable fermentation (cucumbers, carrots, beets)
• Sauerkraut and kimchi preparation
• Kombucha scoby storage and small ferment trials
• Kitchen countertops and compact storage spaces

Key specifications

• Capacity: 1 litre
• Material: clear glass body
• Lid type: fitted lid with integrated airlock mechanism for controlled gas release
• Form factor: compact, cylindrical jar suitable for countertop use
• Visibility: transparent walls for visual monitoring of fermentation

How to use

Prepare vegetables and brine according to your chosen recipe, then pack the ingredients tightly into the jar, leaving headspace for expansion. Close the fitted lid and ensure the airlock is assembled correctly; fill the airlock chamber with water if required by the design. Place the jar at room temperature away from direct sunlight to start fermentation. Monitor the process visually through the glass and venting through the airlock; when fermentation reaches the desired flavour, transfer to cooler storage or refrigerate to slow activity.

Usage recommendations

For reliable results, maintain clean utensils and hands when packing the jar, use the appropriate salt concentration for lacto-fermentation, and check the airlock water level periodically. Avoid overfilling the jar and allow sufficient headspace to accommodate gas production. Store finished ferments in cool conditions to preserve flavour and texture.
