HEFTMAN Fermenting Jar 2 Pack This fermentation jar is the ideal way to create a natural probiotic of your food. It is made of quality glass to create a sturdy container. The one-way valve is a convenient way of letting out the built-up gases from the fermentation process. It does this automatically.

It is far better than having to deal with the hassle of muslin cloths, and much safer because the gases can be easily released automatically. Avoid sterilising with hot, boiling water. We suggest using sterilising fluid for optimal results. Review: Excellent Jar and Jovela are an excellent seller - I am new to fermentation so wanted an easy jar to start. These jars are just that and they are the best priced comparable jars. Using a cold sterilization (diluted Milton 15ml in 4L) and 4 rinses followed by air dry and time in an oven at 130C I got going with a Kimchi, Sauerkraut then these pickled cucumbers. The jars are heavy and worth making sure the lids are fully on and your hands are dry when handling to avoid dropping. When sterilising DO NOT use boiling water in these. Even when using a metal spoon etc to equalize the temperature between water and glass, the glass is so thick that cracking will occur. Another reviewer noted this - and I also made this mistake. If you want to boil or heat to sterilise DO raise the temp gradually from cold. The plastic and silicone lids are great allowing for gasses and liquids to overflow if needed when fermentation starts - without causing explosions! And lids and glass being neutral material there is no risk of corrosion or metal contamination. These are all food safe , BPA free and lead free. Jovela were a great and responsive supplier. Review: Impressed by the quality and design of the jar - I bought this fermenting jar to make my own sauerkraut and kimchi at home. I was impressed by the quality and design of the jar. It is made of strong glass and has a wide mouth for easy filling and cleaning. The lid has a silicone seal that creates an airtight environment for the fermentation process. The best feature of this jar is the one-way valve that automatically releases the excess gas that builds up during fermentation. This prevents the jar from exploding or leaking, and also keeps out oxygen and contaminants that can spoil the food. The valve is very easy to use and does not require any maintenance. I have been using this jar for a few weeks now and I am very happy with the results. My sauerkraut and kimchi are delicious and crunchy, and have a nice tangy flavour. They are also full of probiotics that are good for my gut health. I would recommend this jar to anyone who wants to try fermenting their own food at home. It is a great product that is worth the price. ## Features - STRONG GLASS - This 1.4 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. These fermenting jars fit well in the fridge, and can be stored at room temperature. - AIRTIGHT SEAL - Made with an airtight silicone seal, it ensures there will be no contamination to your food and ensures no oxygen gets in.

It is the most convenient way to release the gases without letting in contamination or oxygen. - 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.

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 ! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent Jar and Jovela are an excellent seller *by L***H on 3 September 2023* I am new to fermentation so wanted an easy jar to start.

I broke one by rinsing out with only about a two teaspoons of recently boiled water which would have been fine in an ordinary bottle. They're a good size to go in my fridge but don't assume your fridge has the same shelf spacing. The valves worked well for brewing kombucha and you can see how the brewing is going. ## Frequently Bought Together - HEFTMAN Fermenting Jar With 1 Way Air Release Vent - 1.4 Litres, 2 Pack - Ideal for Safe Fermentation for Kefir, Kimchi, Sauerkraut, Sourdough Starter, Overnight Oats - Fermentation Jars Pack of 2 - Live Kefir Company, Live Milk Kefir Grains.
