Water kefir

Water kefir grains are a mix of yeasts and bacteria (SCOBY) that ferment sugar water into a lightly sparkling drink. I've been making 2 to 4 litre batches and I'm working out how to scale up towards 30 litres without losing what makes the small ones good.

Kefir grains grow as batches are produced. Excess is removed and stored. My starting kefir grains have now been built up sufficiently for a larger batch size. They're now stored in grain hotel resting while I prepare for a large batch method and also work on other projects.
