Chronicles of Kefir

What is kefir and where did it originated?

Kefir provides a large part of the diet of the mountaineers of the Caucasus, famous for their longevity. It is also known for its amazing healing powers.

One of the first researchers of kefir, V.V. Podvysotsky, came to the conclusion that the  kefir grains were an accidental creation due to the change in starter product. When the tribes from Central Asia steppes moved into Caucasus Mountain, they brought their cultured drink kumis, which is a fermented mare’s milk.  In due course, the horse milk was replaced by more prevalent cow’s milk and the magical amalgamation happened. 

For the first time, the benefits of kefir were officially discussed in the middle of the 19th century. The Tiflis doctor Dzogin told his colleagues in the Caucasian Medical Society about it in 1867. Gradually the rumor about the healing properties of the drink spread far, beyond the Caucasus mountain and even beyond the Russian Empire. 

Today, people around the world enjoy kefir drinks.

How to Make Kefir at Home

Step 1: Prepare for fermentation

Start by ensuring your glass jar is thoroughly clean—this helps prevent any unwanted bacteria from interfering with the fermentation process.

Add your kefir grains to the jar (Pic. 1), then pour in fresh milk, leaving some space at the top for natural expansion.

Give the mixture a gentle stir to break up any clumps of grains (Pic. 2).

Loosely cover the jar with a breathable material such as a towel, cheesecloth , or a coffee filter (Pic. 3) secured with a rubber band (my favorite method).

Let the jar sit at room temperature for 24 hours, away from direct sunlight. You’ll know fermentation has occurred when the milk begins to separate into curds and whey—a sign that the kefir is ready for the next step.

Step 2: Straining the kefir

After fermentation, stir the mixture gently with a spoon or spatula.

Next, pour the contents through a fine-mesh strainer into a clean container. The strainer will catch the grains while allowing the liquid kefir to flow through. Gently press the grains with a spatula to extract as much of the finished kefir as possible (Pic. 4 & 5).

Set the grains aside. They’re ready to be reused!

Pour the strained kefir into a clean glass jar with a lid (Pic. 6), seal it tightly, and store it in the fridge. It will continue to develop flavor and slight carbonation as it chills.

Step 3: Storing and reusing the kefir grains

To continue the cycle, wash your fermentation jar, return the grains, add fresh milk, and start again. You can do this daily or pause anytime.

When you’re ready for a break, simply cover the grains with milk and store them in the fridge. Since kefir grains are a living culture, they’ll need to be “fed” with fresh milk about once a week to stay active.

Over time, your kefir grains will multiply! When you have more than you need, you can:

  • Use in the garden as a probiotic boost
  • Add a spoonful to smoothies with berries
  • Share with friends
  • Feed them to pets (in moderation)

Ways to Use Homemade Kefir

  • Smoothies: Blend kefir with fruits, like berries or bananas for a nutritious drink.
  • Salad Dressings: Use kefir as a base for creamy dressings.
  • Baking: Substitute kefir for buttermilk in recipes.
  • Kefir Cheese: Strain kefir through cheesecloth to make a spreadable cheese.

Tips and Wisdom from Cafe Osharak

  • Feeding the Grains: If you’re not making kefir daily, store the grains in the refrigerator covered with milk and feed them weekly.
  • Grain Multiplication: Over time, your kefir grains will multiply. Share them with friends, add them to smoothies, or even use them in your garden.
  • Fermentation Time: The longer you ferment, the tangier the kefir becomes. Adjust fermentation time to suit your taste.
  • Reactivating Grains: After spending a long time in the fridge, kefir grains can become dormant and less active. To reactivate them, strain the grains and place them in a clean jar. Add just enough milk to cover the grains, then loosely cover the jar and leave it on the counter at room temperature for 1–2 hours.
    The first batch may turn out a bit thin or less tangy, but don’t worry—with each fermentation cycle, the grains will regain their full strength and activity.

Frequently Asked Questions

Can I use non-dairy milk?

Kefir grains thrive on lactose, so dairy milk is ideal. However, you can use non-dairy milk for short periods, but it’s essential to return the grains to dairy milk regularly to keep them healthy.

How do I know if my kefir is ready?

The milk will thicken and may separate into curds and whey. It should have a tangy aroma.

What if I need a break from making kefir?

Store the grains in the refrigerator covered with milk. Feed them fresh milk weekly to keep them alive.
