Review: love using it for Sauerkraut - Great little fermenting jars which are perfect size for a full head of cabbage, love using it for Sauerkraut.

## Features

- STRONG GLASS - This 1 litre fermenting jar is made from quality glass, ensuring it is sturdy for storing fermented products, ideal as your sourdough starter jar, kefir or sauerkraut. It can be washed and used again.
- AIRTIGHT SEAL - Kimchi container made with an airtight silicone seal, it ensures there will be no contamination to your food and ensures no oxygen gets in. This prevents mould from growing.
- ONE-WAY VALVE - The valve automatically releases the built-up gases from the fermentation process, so you can avoid the hassle of muslin cloths! It is the most convenient way to release the gases without letting in contamination or oxygen.
- EASY TO USE - Prior to filling with food, ensure the kombucha jar is clean and dry. Push food down to eliminate air, then seal with the airtight lid. No valve management required: the unique one-way valve in the lid allows built-up fermentation gases to be released automatically. These fermenting jars fit well in the fridge, and can be stored at room temperature.
- FOOD-SAFE - The fermentation jar is safe for food. Simply add your food to create bacteria making it a natural probiotic.
- EASY TO CLEAN - Simply hand-wash these pickling jars with warm, soapy water; avoid sterilising with hot, boiling water. We recommend using sterilising fluid for optimal results.
