How to make kefir

Step 1, heat the milk: warm 1 litre of fresh milk to the required temperature.
Step 2, add the sachet: pour in one sachet of starter culture and stir gently for 3–4 minutes.
Step 3, ferment: let the mixture rest at a steady warm temperature, in a yogurt maker or an insulated container.
Step 4, chill: refrigerate the batch to set the texture.
Step 5, enjoy: serve plain or with fruit, oats or honey.

Exact temperatures and times

  1. 1

    Heat the milk

    Boil 1 litre of fresh milk, then let it cool to 35–40 °C. If the milk is already pasteurised, just heat it to 35–40 °C.

  2. 2

    Add one sachet

    Pour in one sachet and stir for 3–4 minutes so the culture spreads evenly.

  3. 3

    Let it set 12–14 hours

    In a yogurt maker: 12–14 hours at 35–40 °C. The traditional way: wrap the covered pot or jar in a blanket to keep it at that temperature for 12–14 hours.

  4. 4

    Chill

    Refrigerate at 8–10 °C for 6–7 hours.

  5. 5

    Serve

    Kefir stays lighter than yogurt — stir it and drink it as it is, or blend it with fruit.

Good to know

What is the difference between the yogurt and the kefir starter?

The yogurt starter uses Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus; it sets at 42–45 °C in 7–8 hours into thick, spoonable yogurt. The kefir starter is a bacterial and yeast culture based on Lactococcus lactis; it sets at 35–40 °C in 12–14 hours into a lighter, drinkable kefir. Neither needs special equipment.

Which milk works best?

Whole cow's milk gives the thickest, creamiest result. Pasteurised milk only needs warming; raw milk should be boiled and cooled first; UHT milk works but sets a little thinner; skimmed milk sets thin. Plant milks can ferment, but results vary a lot — full-fat oat or soy milk work best, so try a small batch first.

How long does homemade yogurt or kefir keep?

Up to about a week in a clean, closed container in the fridge; it gets slowly tangier. Throw it away if it smells off or shows any coloured mould.

How should I store the sachets?

In a dry and dark place at up to 20 °C, away from the cooker, the dishwasher and direct sun. They do not need the fridge. The best-before date and batch number are printed on the box; shelf life is 24 months from production.
