Kefir (Using Live Kefir Grains)

Kefir grains last forever if you take care of them and they can last for generations. Kefir grains are not really grains but rather combinations of good bacteria and yeasts that infuse your milk or non dairy milk with over 50 good bacteria and good yeasts. They look like little pieces of cauliflower and feel a little rubbery. They’re tough little guys and you can pull them apart, and they just grow more. Kefir grains are a little like having a pet. You have to feed and take care of them, but that’s easy to do and I can show you how. If you need more help, check out our FAQs on Milk Kefir.

Making Kefir

  • Place 1 tablespoon of fresh kefir grains in a glass jar and fill the jar with (2-3 cups) fresh milk. Add less milk if your home is on the cooler side (68 degrees or below). Add more milk if your home is above 75 degrees.
  • Place a lid on the jar and let sit at room temperature for approximately 24 hours (or until the milk has thickened or has become sour tasting). You might see tiny pockets of whey forming, this means it’s done.
  • Pour the kefir slowly into a strainer to separte the kefir from the grains.
  • Then you will see the kefir grains left in the strainer.
  • Add fresh milk to the remaining kefir grains, then the whole process is simply repeated for the next batch. Your kefir grains will grow and multiply each week, so increase the milk or remove some of the grains. You can give your extra grains to friends or pets, or you can even blend them up in the blender with a smoothie and drink them. They are good for you!
  • The kefir that went through the strainer (that came in the jar) can be placed in a glass jar to be consumed immediately. It can also be stored in the fridge. This will last many months in your refrigerator and is preserved by the presence of good bacteria, which keeps the milk safe. However, it will get more sour over time as it will slowly keep fermenting in your fridge. Every 24 hours when your kefir is done, you can add to the batch of the previously made kefir in your fridge or drink it.

Taking a Break from Kefir

Kefir Changes

  • Your kefir can ferment and be thin and pourable or thick like yogurt. The temperature in your house determines how quickly it ferments. In the summer it ferments faster and tends to be thinner. In the winter it ferments more slowly and is usually thicker and creamier

Kefir Seperating

  • If your kefir separates into whey and curds, don’t worry. It’s just a little over fermented and is still good to drink. You’ll need to add more milk or shorten the fermenting time or remove some of the grains. Check out this article for more help. Thick and Thin of Kefir

Creamy Kefir


(*1) Most milk types are acceptable, including whole milk, fat-reduced, non-fat, pasteurized, and homogenized, although I mostly enjoy fresh raw whole cow’s milk to culture kefir.
