Make extra-mild, creamy milk kefir at home, perfect on its own or in smoothies. Heat the milk → Add a sachet → Enjoy it tomorrow This kefir starter leaves out L. bulgaricus, so your kefir stays very mild and creamy even after several batches.

WHY MAKE YOGURT AND KEFIR AT HOME?

1. FRESHER THAN SHOP-BOUGHT: eat your yogurt or kefir within days of making it, while the cultures are at their liveliest.

2. ONLY WHAT YOU PUT IN: just milk and culture. No added sugar, sweeteners, colourings, flavourings or stabilisers unless you choose to add them.

3. YOUR TASTE, YOUR TEXTURE: stop it earlier for mild, later for tangy; strain it for Greek-style yogurt or skyr.

4. SAVE MONEY: one sachet makes about 1 litre, and you can keep reculturing from your own yogurt or kefir, batch after batch.

5. CHOOSE YOUR CULTURE: from classic Bulgarian and Balkan Style to Bifido, Acidophilus, Nordic Style, Kefir and Organic Vegan.

6. IT'S EASY: first batch 12–16 hours in a yogurt maker or any device that keeps a steady temperature for the entire incubation, later batches 3–6 hours.

7. REAL HELP FROM REAL PEOPLE: our YouTube tutorials, Yogurt App, blog, forum and customer service will guide you until you get it just right.
