2tbsp Kefir grains
500ml Filtered water
2tbsp Brown sugar
Firstly in a large 1 litre glass jar, dissolve the sugar in 100ml hot water. When the sugar is dissolved add the remaining cold water. make sure the water is room temperature.
Now add the kefir water grains into the jar and cover the top of the jar with a muslin cloth. The kefir grains are living organisms and feed on the sugar to ferment it.
Leave the jar in a warm, dark place such as an airing cupboard for 2-3 days. Do not leave it for too long or it can starve the grains if there is no sugar left. The longer you leave it, the more acidic the taste is.
After 2-3 days strain the mixture through a small sieve into another glass jar. You can now drink the kefir liquid and store it in the fridge. Try a small glass to see if you like it and if it agrees with you. Keep the kefir grains to reuse.
Wash the fermenting jar and repeat the process again.
If you are going away you can freeze the kefir grains and defrost them to start the process again on your return.
