Our Mason Jar fermentation lids allow gases and thus pressure escape from the glass through the small valve without oxygen getting in. This keeps the glass sterile, no germs get into the glass and the vegetables are guaranteed to stay fresh. A small cross slot on the fermentation valves ensures this effect.
In our shop you will find matching food-safe weights made of glass and a wooden pestle – so you can work and ferment directly in the glass! Are you looking for a complete starter kit? You can find everything you need for fermentation in our fermentation set .
The fermentation attachments are made of food-safe silicone and are available in a set of 4.
The fermentation attachments are of course dishwasher safe. However, you should always sterilize the attachments in a hot water bath before using them again.
