If you like something creamy over your porridge in the morning and something fizzy in the afternoon, the kefir duo is your set. No milk, plenty of bubbles, and a use for all that tea in the cupboard: water kefir and kombucha. Everything at once, with the biggest saving: the complete starter kit. Same cultures, same quantities, same guides as the water kefir grains, milk kefir grains and kombucha SCOBY on their own: only the price is lower.
Your first fortnight with a set
Day 1: get everything going
Set the water kefir with 1 litre of water, 4 tablespoons of cane sugar, a dried fig and a slice of lemon. Milk kefir grains go straight into a litre of whole milk. For the kombucha, brew a strong pot of tea, sweeten it, let it cool and add the SCOBY with its starter liquid. Ten minutes in all.
Day 2: your first kefir
Strain, bottle and set the next batches straight away. The first batches can be a little shy while the grains settle in: the first days explains what to expect, and how to make milk kefir covers the creamy one.
Day 3 to 4: the fizz arrives
After 24 to 48 hours in a closed swing-top with strawberries, lemon or ginger, the second fermentation gives you a properly sparkling bottle.
Day 7 to 10: the kombucha is ready
Taste it with a straw: when it is pleasantly tart, bottle it, keep a cup back for the next batch and start again. How to make kombucha takes you through every step.
Every guide comes with your set, and the complete pages on water kefir, milk kefir and kombucha go into every detail. Still weighing up the drinks? Kefir or kombucha and water kefir or milk kefir put them side by side.
Add the ginger beer plant
Fancy one more drink? The ginger beer plant makes real old-fashioned ginger beer: fresh ginger, water, sugar and a couple of days, then 48 hours in a closed bottle for a proper pop. Add it to the water kefir and kombucha set or to the kefir duo and your order comes to more than £35, so standard tracked delivery is free.
