Water kefir 101 – Day 2 of 2nd fermentation at room temperature.
Once you have completed the initial fermentation which includes the grains, strain the brew, and at this point you can decanter it into bottles. Pop on an airtight lid and let it stand for a further 2 days+ to build up carbonation. Then refrigerate.
(Ensure you continue to release some of the build up pressure every few days or so to avoid bottles exploding.)
