How To Make Kefir: A Step-by-Step Guide to Homemade Fermented Goodness

Kefir, a probiotic-rich fermented beverage, can be easily made at home with a few simple ingredients and basic equipment. This article will guide you through the process of making kefir, allowing you to enjoy the benefits of this delicious and nutritious drink in the comfort of your own home.

What You’ll Need

To make kefir, you’ll need the following:

  • Kefir grains: These are the living cultures responsible for fermenting the milk. You can obtain them from a friend or purchase them online or at health food stores.
  • Milk: Kefir can be made with various types of milk, such as cow’s milk, goat’s milk, or plant-based milk alternatives like coconut milk or almond milk.
  • A glass jar: Choose a clean glass jar that is large enough to hold your desired quantity of kefir.
  • A non-metal stirring utensil: Use a plastic or wooden spoon for stirring, as metal can react with the kefir grains.
  • A breathable cover: Use a cloth or coffee filter secured with a rubber band to cover the jar during fermentation.

Step-by-Step Instructions

Follow these simple steps to make your own kefir:

  1. Place the kefir grains in the glass jar.
  2. Add the milk to the jar, leaving some headspace for expansion during fermentation.
  3. Gently stir the milk and kefir grains together.
  4. Cover the jar with a breathable cover to allow airflow.
  5. Place the jar in a warm spot, away from direct sunlight.
  6. Allow the mixture to ferment for 24 to 48 hours, depending on your desired taste and consistency. The longer the fermentation, the tangier and thicker the kefir will become.
  7. After the desired fermentation time, separate the kefir grains from the liquid. You can do this by straining the kefir through a fine-mesh sieve or by gently scooping out the grains with a non-metal spoon.
  8. Transfer the strained kefir into a clean jar or container for storage.
  9. Refrigerate the kefir to slow down the fermentation process and enjoy it chilled.

Tips and Variations

Here are a few tips and variations to enhance your kefir-making experience:

  • Experiment with different types of milk to discover your preferred flavor and consistency.
  • Adjust the fermentation time to achieve the desired level of tanginess and thickness.
  • Flavor your kefir by adding fruits, vanilla extract, honey, or other natural sweeteners after fermentation.
  • Reuse the kefir grains for subsequent batches by adding them to fresh milk.


Making kefir at home is a rewarding and simple process that allows you to enjoy the benefits of this probiotic-rich beverage.
