“It’s my first time. Which kefir should I buy?” We hear this question every week. The good news is that every one of our kefirs is fermented with living grains, so you cannot pick a wrong one. You only need to pick the one that suits your taste and your day. Here is how.

The short answer

Original milk kefir: creamy and gently tangy, with no added sugar. Choose it for a daily glass for the whole family.
Fruit milk kefir: the same kefir with fruit jam at the bottom. Choose it for your first bottle or for children.
豆奶克菲爾優格, our soy kefir: made from soy milk, with a rich soy flavour. Choose it if you are lacto-vegetarian or love soy milk.
Water kefir: light, fruity and lightly sparkling, with no caffeine. Choose it in place of a soda or kombucha.
Kefir grains: live grains that turn fresh milk into kefir at home. Choose them for the fun of making your own.

Original milk kefir: a daily glass for the whole family

This is our classic kefir. It is fresh whole milk fermented for 24 hours with living kefir grains. The grains are strained out, and the kefir goes into a 500 g bottle.

Who loves it: people who want their probiotics from an everyday food instead of capsules. The lactic acid bacteria and yeasts from the grains help digestion.
How it tastes: gently tangy with fine bubbles, a little like unsweetened Greek yogurt. That is why kefir is called “milk champagne”.
What is inside: only milk and kefir grains, with no added sugar. Every 100 g contains 4.0 g of protein and 110 mg of calcium.
How to enjoy it: drink it from a glass, pour it over oats and fruit, or blend it with a banana. New to kefir? Start with a small glass and add a little honey.
How long it keeps: 21 days unopened in the fridge. Once opened, finish it within 3 days.

Fruit milk kefir: the easiest first bottle

This is the same milk kefir, with fruit jam and fruit pieces at the bottom of a handy 240 g bottle. The fruit makes the first sip easy, and many people love the kefir taste after a few bottles.

Who loves it: first-time kefir drinkers, children, and anyone who likes a sweet and tangy drink.
Eight flavours: blueberry, strawberry, mulberry, mango, cranberry, pineapple and passion fruit, plus the original. Our customers buy the original, strawberry and blueberry most.
How to enjoy it: open the cap slowly to let the gas out, close it, then shake well so the fruit mixes in. One bottle is just right for one go.
How long it keeps: 14 days unopened in the fridge.

Soy kefir: for lacto-vegetarians and soy milk lovers

Our 豆奶克菲爾優格 is unsweetened soy milk from non-GMO soybeans, fermented with kefir cultures. We add inulin from chicory root, which feeds the cultures. You drink the cultures and their food together.

Who loves it: lacto-vegetarians, people who love soy milk, and anyone who wants a plant-based daily kefir in place of probiotic capsules.
How it tastes: the soy milk flavour you know, richer, with a fresh, light tang and fine bubbles. It is smooth enough to drink straight from the bottle.
What is inside: the original has no added sugar. One 240 g bottle has 1.4 g of sugar and 8.2 g of plant protein.
Seven flavours: the original, plus mulberry, cranberry, strawberry, mango, passion fruit and pineapple.
How to enjoy it: swap your breakfast soy milk for a bottle, with a dan bing or a rice ball. It is also good with overnight oats, or in your gym bag. Shake it gently before you drink.
Allergens: contains soy. May contain traces of milk, because the grains have been grown in milk.
How long it keeps: 14 days unopened in the fridge, best in the first 7 days. Once opened, finish it within 3 days.

Water kefir: a sparkling drink with no caffeine

Water kefir is water and organic cane sugar fermented with water kefir grains, then fermented again with dried fruit and flowers. It comes in a 330 ml can and is vegan.

Who loves it: anyone who wants a tasty drink in place of a soda or kombucha. Kombucha is made from tea and has caffeine; water kefir is made from water, so it has none.
How it tastes: lightly sweet and lightly tart, with a fine natural fizz. It is best ice cold.
Three flavours: blueberry is berry-sweet with a gentle tang from roselle. Osmanthus is floral, with the gentlest fizz. Strawberry is the sweetest and the fizziest.
How to enjoy it: with lunch, in the afternoon, after hotpot or barbecue, or in the evening. One can is one serving. Chill it well and open it slowly.
Good to know: the osmanthus flavour contains mango. All flavours are made in a facility that also handles milk.
How long it keeps: 35 days unopened in the fridge. The date is printed on the can.

Kefir grains: the fun of making your own

Kefir grains are small, living clusters of lactic acid bacteria and yeasts. They look like tiny white cauliflower florets. Put them in fresh milk, and a day later you have your own kefir.

Who loves them: people who enjoy cooking, families who like a kitchen project, and anyone who wants fresh kefir every day.
How it works: put the grains in whole fresh milk and leave the jar at room temperature for about 24 hours. 24°C is best. Then strain, and put the grains back into fresh milk for the next batch.
Two sizes: 10 g of grains makes 100–300 ml a batch, and 20 g makes 200–600 ml.
Everything to start: every option comes with 6 tools and a 5-page manual. The starter kit adds a 1-litre glass jar and a plastic strainer.
Your grains grow: with fresh milk every day, you will see them grow within 1–3 weeks. Keep them below 35°C.
Your kefir keeps: up to 21 days sealed in the fridge.
Prefer a sparkling drink? Our water kefir grains starter kit makes water kefir at home, with 60 g of sugar and 60 g of grains per litre of water.
