Working with live cultures that just magically appear (well they have been there all the time, but we just can’t see them with the naked eye) and turn your cabbage into sauerkraut is exciting. The health benefits of this “slow food” are so numerous and as human beings we are finding our way back to traditional ways of preparing food for maximum nutrient retention, preservation of food and increased well-being.

The fermentation jar includes the below items:


Glass Jar
1 litre wide mouth glass jars with stainless steel compound lid.
The jar is great for lacto-fermentation of vegetables like sauerkraut and kimchi. It can also be used for yoghurt and kefir making and kombucha. The airlock  and the weight fit these jars perfectly. The regular lid is used to store the ferment in the fridge after fermentation is complete.


Glass Weight
This glass fermentation weight is heavy and sturdy. It is easy to put in and to fish out of the jar by grabbing the center handle. It is heavy enough to keep down the most vigorous ferments and it is really easy to clean by hand or in the dishwasher.
Measurements: Diameter is 70mm, depth 25mm.

Airlock
Comes with a silicone fermenting airlock. It is used during the active fermentation period at room temperature. it is perfect for keeping lacto-fermented pickles and drinks under an airlock during fermentation. As pressure builds up gas pushes out the top of the spout without letting air in.
Made from FDA approved, food-grade silicone, which can be washed in the dishwasher and reused.
When ferment is finished, simply remove weight and airlock and fasten regular lid onto the jar and store in the fridge.
Colour will be randomly selected unless you let us know your choice when placing your order. These are the colours you can choose: blue, green, purple, red/pinkish, white.

Thanks for the great jars

I've just recently received my order for 2 x Fermentation Jars with the airlocks and weights. The parcel arrived in perfect condition and the tracking of it was excellent ?. <br /> <br /> I'm really excited about using these jars. I'm hoping to make my own Kimchi - once my chinese cabbage is harvested - and your fermentation jar setup is fantastic and just the thing I was looking for! <br /> <br /> Thanks also for the informative instructions inside each jar - very thorough and helpful indeed.<br /> <br /> Have a great Christmas and thanks again for the great jars.

Very sturdy

A great jar with fitting weight and airlock. Comes at a great value and everything is sturdy and will last me a lifetime of fermenting.

Works well.

A fabulous set to make fermented foods. I use it on a regular basis and love the weight and airlock.

Glass weight

unfortunately the glass weight was too tight a fit for the jars they came with and on attempting to remove the weight after fermentation the jar shattered. The silicone air vents worked really well though.

Fermentation Jars

I've had these for a few weeks now, they are fantastic to use easy to clean and very well priced too. Already got 4 different fermented veges in the fridge and just started 2 more today. Great product.

Love the fermentation jar set

It arrived quickly and with great instructions. Very happy with what was in the box and we've already put it to use making collard sauerkraut. Feels like a quality product which will last us for years.
