Review: Brilliant ferments - I read the reviews about these breaking but went ahead and I'm really glad I did. I sterilize with Milton and had a batch of red cabbage with garlic and caraway seeds going for 3 weeks. It's gorgeous, really tangy and very tasty. My first lot with white cabbage was ok, but not as good as red cabbage. According to taste obviously.. The jars leaked quite a bit when fermenting started but that is good news. I put mine in a tray so no probs. I put weights in and topped up to keep it going. Really easy to do and no worries about burping the jars. Very happy with the results and my gut is too. Great jars. 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. ## 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. 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. - 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B091HRSKD5 | | Best Sellers Rank | 12,598 in Home & Kitchen ( See Top 100 in Home & Kitchen ) 5 in Fermenters | | Closure type | Screw | | Container Shape | Round | | Customer Reviews | 4.2 4.2 out of 5 stars (1,663) | | Date First Available | 1 April 2021 | | Dishwasher safe? | Yes | | Is microwaveable | No | | Item Weight | 1.36 kg | | Item form | Jar | | Item package quantity | 1 | | Item volume | 1.4 Litres | | Item weight | 1.36 Kilograms | | Manufacturer | HEFTMAN | | Model Number | HMFJ | | Product care instructions | Refrigerator Safe | | Product dimensions | 12.4L x 12.4W x 17H centimetres | | Recommended uses for product | Fermentation | | Set Name | 2 | | Size | 1.4 liters | | Special Features | Waterproof | | Special feature | Waterproof | | UPC | 759049739623 | ## Product Details - **Brand:** HEFTMAN - **Capacity:** 1.4 litres - **Colour:** Red - **Material:** Glass - **Material feature:** Durable, Non-Porous, Dishwasher Safe, Stain Resistant ## Images ![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 - Image 1](https://m.media-amazon.com/images/I/71fSbrNxH+L.jpg) ## Available Options This product comes in different **Color** options. ## 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 ! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Brilliant ferments *by K***H on 11 February 2025* I read the reviews about these breaking but went ahead and I'm really glad I did.

Doesn't come with any instructions regarding care so I hand wash as it does not state if dishwasher safe. ## 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.
