- FOOD-SAFE & EASY TO USE - Prior to filling with food, ensure the fermentation 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. Simply add your food to create bacteria making it a natural probiotic.
- EASY TO CLEAN - Simply hand-wash with warm, soapy water. Avoid sterilising with very hot or boiling water. We recommend using sterilising fluid for optimal results.

## Questions & Answers

**Q: please can someone tell me how the valves work on top. do i need to lift them up? push them down? or how does it work as no instructions in the box.**
A: I'm the same, there is no explanation as to whether you are supposed to do anything with the two little valves. In fact they don't move much at all, so I presumed there was nothing to do with them. If there is something you are supposed to do to the valves, it would be nice if there were some guidelines or instructions!

**Q: Very tight stubborn lid that won’t budge even with jar opening tools and the lids are plastic, any suggestions?**
A: Have you tried removing the valve, sometimes helps a bit like punching a hole in a tight jam jar lid to release the vacuum.
I eventually got rid of my jars because I couldn't grip the lids and the valves stopped working.

**Q: Can the lid go in the dishwasher?**
A: I’ve put the lid on the top shelf of the dishwasher without any problems

**Q: Do you need a fermentation weight hor this product. I want to ferment cherry tomatoes**
A: Great jars, if you haven’t got weights and the ingredients need to be kept under 
fluid, some people say use a heavy pebble, wrap it in plastic, works a treat !
Only used mine for kefir so far, about to do sauerkraut, so I’ll use anything small enough to get into the jar that’s heavy ! Probably better to buy the weights for the job !
