Ingredients
  

  • 1 –2 tablespoons kefir grains live culture
  • 4 cups raw milk cow, goat, or sheep milk, or a non-dairy alternative like coconut milk

Equipment:

  • Glass jar 1-quart size
  • Breathable cloth or coffee filter
  • Rubber band or jar lid
  • Non-metallic strainer
  • Bowl for straining

Instructions
 

Prepare the Jar:

  • Place 1–2 tablespoons of kefir grains into a clean glass jar.

Add Milk:

  • Pour 4 cups of raw milk into the jar, leaving about an inch of space at the top.

Cover and Ferment:

  • Cover the jar with a breathable cloth or coffee filter and secure it with a rubber band.
  • Let the jar sit at room temperature (68–75°F or 20–24°C) for 24 hours, away from direct sunlight.

Check Consistency:

  • After 24 hours, check the kefir. It should have thickened slightly and smell tangy. If it’s too thin, let it ferment for another 6–12 hours.

Strain the Kefir:

  • Place a non-metallic strainer over a bowl and pour the kefir through it to separate the grains.

Store and Enjoy:

  • Transfer the strained kefir to a clean jar or bottle and refrigerate.
  • Rinse the kefir grains (optional) and reuse them for your next batch.

Notes

  • Milk Options: Use raw cow, goat, or sheep milk for traditional kefir. For a dairy-free version, try coconut milk or almond milk (note: non-dairy options may require adjusting fermentation time).
  • Fermentation Time: In warmer climates, fermentation may take less than 24 hours. In cooler environments, it may take longer.
  • Second Fermentation: For added flavor, let the strained kefir sit at room temperature for another 6–12 hours before refrigerating.
  • Storage: Fresh kefir lasts up to 1 week in the fridge. Kefir grains can be stored in a small amount of milk in the fridge for up to 1 week if you’re taking a break.
  • Troubleshooting: If your kefir tastes too sour, reduce fermentation time. If it’s too thin, use more grains or ferment longer.
