Water kefir grains: your questions on ordering, delivery and arrival

Water kefir grains: they make the easiest homemade drink to get right, ready the next day. If you also like tea, look at the water kefir and kombucha duo; for a family, the kefir duo; to try everything, the complete kit. Compare the range.

Water kefir turns sweetened water into a fruity sparkling drink. Milk kefir turns milk into a creamy, drinkable kefir. Kombucha is a sparkling fermented tea with deeper flavours. The ginger beer plant makes a spicy homemade ginger beer. They are four separate cultures and cannot be swapped for one another.

30 g makes about a litre of drink a day, ideal for one or two people. 60 g makes about two litres a day, for a family or for two flavours at once.
