HEFTMAN Fermenting Jar with 1 Way Air Release Vent - 1.4L, 2 Pack (Red)

These are high quality glass jars. The lids fit tightly and the vent works very well. I would 100% recommend them.

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.

Used it make Kefir for the first time, so was obviously nervous. It came out perfectly!! I read all the instructions, which does tell you NOT to put in dishwasher. I inadvertently did and it came out cracked. Totally my own fault, so just a warning, abide by the instructions and all will be well. Great product. 👍

These will take only very gradual changes in temperature, ie very little thermal shock, before the bottom falls out. 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.

Great idea but rhey are not fit for purpose. As others have said, the bottom of the glass breaks upon ANY temperature change. Going from fridge to cold tap water did it to mine upon second use. Shame as otherwise very handy, but I won’t be buying again.

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.

These jars are so easy to use and are great for fermenting relatively large amounts of sauerkraut or kimchi. Simply put in your veg and other ingredients, according to the recipe, and forget about it for a couple of weeks. So much safer and easier than using jars with sealed rims that require burping daily, and therefore allow in air (plus airborne bacteria & mould). They also look highly attractive on the kitchen worktop packed with brightly coloured veg. These jars are perfect for adopting a healthy probiotic diet. Everyone should try this as a cheap way to make fermented foods and drinks that are otherwise highly priced to purchase. Whatever you do, don’t sterilise them with boiling water as they crack. I learnt this the hard way but was incredibly impressed by the customer service of this company as they very kindly and quickly sent me a replacement when I explained what I’d done. This level of customer service is incredibly rare, so where’s the 6th star option?

As jars they were great but It was difficult to take off the tops The airlocks didn't seem very high quality or easy to use

Doskonały produkt, do tej pory różnie mi wychodziły kiszonki (czytaj nie wychodziły). A tu miłe zaskoczenie, ukisiłam rzodkiewkę. Wyszła super, zero pleśni. Polecam gorąco te słoiki.

Bra storlek 1,4 L och bra kvalitet. Smidigt med stor öppning på glaset!

Los botes están muy bien y son muy fuertes los utilizo para hacer kéfir y la verdad se ha dicho que me van muy bien y son fuertes y resistentes así que los recomiendo

Ich benutze sie für meinen Wasserkefir. So ist er gut geschützt und kann "atmen".

Me encantan estos botes, durante un tiempo estuve haciendo kéfir, he comprado más porque me van muy bien para hacer también encurtidos Chucrut,etc.. son robustos.
