Kefir Grains UK › First week

The first week with your kefir grains, day by day

In short

Grains that have travelled need two to four days to wake up. The first two jars stay thin and only slightly sour; the third thickens; from day four the kefir is creamy, lightly fizzy, and the grains start to grow. Every morning, the same five minutes: strain, fresh milk, same spot. Don't rinse, don't switch milks, don't give up on day two.

The daily routine

  1. Strain

    Pour the jar through a plastic sieve over a bowl, stirring gently with a plastic spoon.

  2. Fresh milk

    The grains, unrinsed, into a litre of whole milk in a clean glass jar.

  3. Lid resting on top

    Not screwed down, so the gas can escape.

  4. Room temperature

    20 to 25 °C, out of the sun, for 24 hours.

  5. Bottle the kefir

    Into the fridge; it keeps a week.

Day by day

4 to 7Creamy, a light fizz, grains growingThe 24-hour routine

Normal or not?

Normal: grains floating or sinking, sticking together, whey at the bottom, a yeasty smell, thin kefir for the first three days. Not normal: a rotten smell or a pink or green layer. Then send a photo before doing anything.

Still runny after a week?

Three usual causes: a cold kitchen under 18 °C (give it 36 hours or a warmer spot), skimmed or plant milk (switch to whole milk), or too much milk for 20 g (go back to one litre or less). White, firm, fresh-smelling grains are alive and will get there.

First-week questions

Can I drink the first day's kefir?

Yes, it is just mild and thin. Many people use it in pancakes or a smoothie.

My grains aren't growing yet. Is that bad?

No. They usually start growing in week two, with whole milk and a steady 24 hours.

Can I send a photo?

Yes, to hello@natural-probio.com: the jar and the grains in the sieve, in daylight. Usually answered the same day.
