How To Make Milk Kefir

We’re breaking down the basics of how to make homemade milk kefir, a probiotic-rich fermented drink that’s soon to be a staple in your kitchen! This easy fermentation project is incredibly simple and produces perfectly creamy kefir in about 24 hours.

After having delicious success with home brewing kombucha, I got to thinking about what other tasty fermented things we could brew up at home. And over the course of a day I went from not having a clue how kefir worked to biking across town to buy my very first kefir grains from a passionate home brewer.

I spent the next few weeks getting to know my new kefir baby. Our relationship was first one of fear. When I wasn’t scared of killing it, I was scared of drinking it. But after a few weeks, I started to get the hang of what it needed (and it started to turn out some delicious kefir!).

So years later, after fermenting hundreds of batches of kefir at home, I’m excited to share with you the secrets to seriously delicious, creamy, homemade kefir. Click the links below to jump around the post, or scroll on to dive into the world of homemade kefir!

Okay, so What is kefir?

For the unfamiliar, kefir is a thick, fermented milk drink. It tastes a bit like plain Greek yogurt – slightly sour and ultra-creamy. But even more so than most types of yogurt, kefir is jam-packed with all kinds of gut-friendly probiotics!

What are kefir grains?

To start off this kef-venture, you’ll need to get your hands on some kefir grains. Kefir “grains” are the engine of this whole process, containing all the yeasts and bacteria needed to ferment the milk into creamy kefir. (The gluten-free folks don’t need to worry – these aren’t true grains, but rather rubbery, cellular structures).

They’re like what the SCOBY is to kombucha, only instead of looking like alien pancakes they look like cauliflower! But unlike kombucha, you cannot grow your own kefir grains and will need to acquire them somewhere.

The best milk for making kefir

The only other ingredient besides kefir grains in this recipe is the milk! You’ll want to use pasteurized milk to start, but can switch to raw milk slowly after a few weeks of getting your kefir grains used to their new environment.

In terms of fat level, the grains will be a lot happier in whole milk, though you can slowly transition to a lower-fat option over time.

And finally, though you can use cow’s or goat’s milk, though I’ve only had experience with whole cow’s milk for making kefir.

Be sure to try our other fermentation projects, like kimchi, Greek yogurt, tepache, and kombucha!

kefir Commonly Asked Questions

How do I take a break from making kefir? Give your kefir grains fresh milk, cover with paper towels or coffee filters as described, then set in the refrigerator. This dramatically slows down the fermentation process, so you will only have to change out the milk every 1 to 2 weeks (or when you see the milk separating into layers).

Why did my kefir form a yellowish watery layer on the bottom? This is normal! When the milk separates into layers, it’s a sign that the kefir as “eaten” everything it can. You can prevent it by either reducing the time you let it ferment (ex: 18 hours instead of 24), or by giving it more milk. It depends on your grains, house temperature, and milk, so don’t worry if it takes a few batches to understand how your kefir will brew best.

Why do I have to use non-metal everything? Metals can hurt the microbial wonderland that is kefir. Avoid contact of the kefir with metal where possible (and definitely don’t brew the kefir in a metal vessel).

What are the health benefits of kefir? As with other fermentations, kefir is full of probiotics which promote good digestion and a healthy gut. The fermentation also breaks down a lot of the lactose in the milk, meaning kefir may be more easily digested than other dairy products for people with lactose intolerance.

Is milk kefir the same as water kefir? Milk and water kefir are two different types of fermentations, using different ingredients and different kefir grains. You cannot use milk kefir grains to make water kefir.

Can you flavor kefir? Yes! 1 cup of kefir can be flavored by blending in fresh fruit (¼ cup), chocolate (1 Tbsp cocoa powder), vanilla (¼ tsp vanilla extract), or dates (1 pitted date).
