Ingredients
  

  • 1 tsp dehydrated milk kefir grains
  • 1 cup organic milk

Instructions
 

  • Rehydrating the Grains:

    Place 1 tsp of dehydrated kefir grains in a glass jar.
    Add 1 cup of organic milk at room temperature.
    Cover the jar with a breathable cloth or coffee filter and secure it with a rubber band.
    Allow the grains to rehydrate at room temperature (68-85°F) for 3-7 days, changing the milk every 24 hours. The grains will gradually regain their full strength.
    Strain and Discard:

    After 24 hours of fermentation, strain the liquid using a strainer.
    Discard the liquid, as it may not be fermented enough for consumption during the rehydration process.
    Repeat this step daily for 3-7 days, adding fresh milk each time.
    Checking for Active Grains:

    After several days, your kefir grains should become plump and active.
    You’ll know they’re ready when the milk begins to thicken and tastes tangy.
  • Making Kefir:

    Once fully rehydrated, place the grains in fresh milk and let it ferment for 24-48 hours, depending on your taste preferences.
    Strain and enjoy the kefir!
    Maintaining Healthy Grains:

    Keep your kefir grains in regular use by repeating the fermentation process with fresh milk every 24-48 hours.
  • If you need a break, store the grains in the fridge with fresh milk for up to 3 weeks. Be sure to “feed” them with a little milk to keep them alive.

Notes

Always use non-metal utensils and jars to avoid harming the kefir grains.
The better the milk quality, the better your kefir will be!
