Step 1: Rinse the grains

Rinse your kefir grains with either milk or water. Make sure that the water you use is non-chlorinated and filtered.

Place your rinsed kefir grains on a dehydrator (Paraflex) sheet.

Step 3: Set up your dehydrator

Step 4: Wait patiently

Let the kefir grains get rid of moisture for 3-4 hours in the dehydrator.

Step 5: Check for moisture

If there is still some moisture, then grant the grains one to two additional hours. Go with your judgment on this. It’s best to keep it for an hour more and check again to avoid overdrying.

Choose a breathable lid to cover up your laid-out kefir grains. Covering them up will ensure that nothing bad from the environment will enter your kefir grains.

Step 4: Wait for them to dry

  3. Then, using a sieve, wash the mixture with lukewarm water.

Reactivating kefir grains

After rehydration, you need to reactivate your kefir grains. To do so, follow the steps below!

Day 1 to 7 of reactivation

The following steps should take place over a period of 7 days.

  • Put the milk kefir grains in a jar.
  • Put half a cup of milk (125ml) in your kefir grains and cover the jar.
  • Let the grains sit at room temperature for 8 hours.
  • After that, mix the grains on a regular basis by shaking the jar. This will ensure that the milk comes into contact with the grains properly.
  • Wait for 24 hours, then rinse the grains with warm water and filter them using a sieve. Repeat every day.

Note: Never use hot water! It will kill your grains.

  • Begin taste testing on day 3. You can drink your milk kefir once its taste and smell are good (usually by the 5th day). Plus, double the milk when you see that the fermentation has begun (between day 3 and day 5).
  • If you think your milk kefir is becoming too acidic or coagulated after 24 hours or less, then either remove half the amount of your kefir grains or double the milk.

Day 7 onwards

  • You don’t have to rinse the grains anymore. Just make sure to milk them regularly.
  • After a month has passed, your grains will be thicker. This is because the grains start multiplying properly after 4 weeks.
