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

These jars are first class! They do their job very well indeed! As long as you read the instructions before use, I can't see there being any problems!

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.

Bought these as a gift for my sister that wanted to try making her own kimchi!They are very good especially on the seal...a bit too good I'd say as it was very hard to open them if we close the lid tightly!Still we use them frequently.

Absolutely brilliant jars - I use these for my sourdough bread starters. After a "feeding", 4-5 hours later you see the starter bubbling away and can hear the gentle hissing and popping of the gases being released by the vent valve. They are a good diameter and short-ish height to fit well in the fridge too. Love them. The chalk pen and black labels are excellent too.

Really bad qualityThe first one cracked and broke when I was washing it for the first time with warm water.The second one cracked and broke after 3 uses nearly cutting my hand - again I was running warm tap water …Not worth it at all!Should be removed from amazon because it’s dangerous and people pay for rubbish !

Order received promptly and just what I wanted so thank you and I will be purchasing some more soon once I’ve started my new fermentation hobby

As jars they were great butIt was difficult to take off the topsThe airlocks didn't seem very high quality or easy to use

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.
