Ferment faster & better

Asked Questions
Can I ferment in any jar?
Can I ferment in any jar?
Absolutely, but every jar will work a bit differently.
If you would like to ferment with twist-off jars or mason jars, you can use the Airtender Lid Punch to make a perfect hole in metal lids. You will need to insert a "water lock" in the hole, so the fermentation gases can escape. This type of accessory can be bought in most (online) shops that sell canning accessories.
You can also use Clip Top Jars and traditional Weck-style jars with Airtender vacuum lids. The bonus is that you can kickstart the fermentation process by creating a vacuum in the jar. And use the same jar after fermentation to vacuum seal your food and keep it fresh up to 5x longer.
Which clip top jars are compatible?
Which clip top jars are compatible?
The Airtender vacuum lids fit the most commonly available size clip top jars, often referred to as "85"or "90". This means that they are compatible with multiple designs and brands, such as Bormioli Fido, Kilner and IKEA, as well as many private label brands.
Because of the large number of brands and jar designs, as well as the nature of glass production, it's always possible that lids do not properly fit certain jars. If you arew uncertain about the compatibilty with our jars, please do not hesitate to contact us.
Alternatively, you can select any of the complete sets of jars with lids and Airtender vacuum pump.
Why can I store food longer with vacuum?
Why can I store food longer with vacuum?
Food loses quality when it’s exposed to air. It’s the reason that, for example, cookies and cereals lose their crispiness. That process is called “oxidation”. So, by removing the air from a jar, you slow down oxidation and your food stays fresh and full of flavour and nutrients.
The second reason that food spoils is bacteria. For example, when strawberries and blueberries get soft and moldy. Most bacteria need oxygen to work. So, remove the air and, again, you will slow down loss of quality.
Although air is the most important factor, there are more factors that contribute to spoilage, such as temperature and sunlight. And, of course, the condition of the food before storage and hygiene when handling and preparing food.
