You love lemonade and fizzy drinks
Start with water kefir grains, our Best Seller (you will also see them called sugary kefir grains or tibicos). They are the easiest and the quickest, and the result is the closest thing to a homemade lemonade. Bottle it with allotment rhubarb or June elderflower for a second fermentation and the fizz will surprise everyone at the table.
Your mornings start with porridge, yoghurt or a smoothie
Milk kefir grains slot into your routine without changing a thing: the same milk, a jar and a sieve. Thick and tangy, on its own, over your oats, in a smoothie, or in the scones where buttermilk would normally go.
You drink a lot of tea and you are in no hurry
The kombucha SCOBY needs a week, but hardly any work, and every tea gives a different flavour. If there is always a box of strong breakfast tea in the cupboard, you have half the ingredients already: a proper brew, a little sugar, and the SCOBY does the rest. Kombucha is the most aromatic of the four.
You like it hot and lively
With the ginger beer plant you make real ginger beer: fresh ginger, not much sugar, plenty of fizz. Perfect for a barbecue and for an alcohol-free Moscow mule.
You would rather make cheese
Not a drink, but the same pleasure of making it yourself: with liquid calf rennet and good fresh milk you have a fresh cheese by the evening. Everything is in cheese making at home.
