1L Clip Lid Glass Kefir Jar
A classic 1 litre glass jar with a clip lid, and just the right size for brewing kefir at home. Pop your grains in, top up with milk or sugared water, and you'll make around 700 to 750ml per batch.
The clear glass means you can keep an eye on your brew without disturbing it, and when it's not busy brewing it's lovely for jams, chutneys and dried foods too.

Using it for kefir
For milk kefir, you can brew with the lid closed, but open it at least once a day to release the pressure. For water kefir, cover the jar with a cloth for the first ferment, then bottle for fizz. Always leave a little space at the top, and wash the jar in warm soapy water (not boiling) before first use.
Pairs well with
- Water kefir grains or our milk kefir grains
- Plastic rimmed sieve, for straining out your grains
- Milk Kefir Home Basic Starter Kit, if you're just getting started
