What Is Milk Kefir?

It is important to understand the essence of kefir before attempting to make this drink at home. Milk kefir is not just some random beverage that you can get by simply mixing a few ingredients together. The truth is that (don’t freak out) live cultures are used to produce kefir. And, yes, you would have to use those too, if you want to end up with a healthy, fizzy drink.

The great news is that making milk kefir requires only two ingredients. The actual milk and kefir grains. The latter are tiny beads that look like grains but have nothing to do with the cultures that contain gluten. Milk kefir grains are gelatinous little fellows that contain strains of bacteria and yeasts. That doesn’t sound extremely appealing, but these living cultures are exactly what turns the milk into kefir. Milk kefir grains use the sugar from the milk (lactose) and turn it into lactic acid. During the process, carbon dioxide is released. Thus, milk kefir is a fermented, cultured drink.

The beverage is quite similar to yogurt, except for the fact that you can actually drink it. Kefir has a sour taste and a pleasant fizz.

  • The History of Kefir

Milk Kefir History - Where do Kefir Grains Come From

Even though nowadays you can easily make both milk and water kefir at home, the original beverage was made of milk.
Many centuries ago, kefir was discoverd in the Caucasian Mountains. The shepherds have figured out that fresh milk can turn into a new beverage after it had been carried in leather pouches for several days with the addition of kefir grains.

Kefir was considered to be a drink with magical powers. That might have been the main reason, why not a lot of people knew about the beverage for centuries. The recipe was kept in secret by the people of the Caucasian Mountains. The legend says that the beverage would have lost its magical strength if the recipe was passed to someone else. However, Marco Polo once mentioned this unique drink in his writings. In you want to know more details about the origins of kefir we have made a seperate article on this topic.

Thankfully, nowdays kefir has become popular in the United States and Western Europe. Before that, the beverage was broadly known only in Southwestern Asia and Eastern and Northern Europe.

What Are the Main Differences Between Milk and Water Kefir?

You might already know that there are two different types of kefir. And though milk kefir is more of a traditional beverage, modern people have also managed to combine the kefir culture with sugar-water solution in order to create water kefir.

So, basically, the main difference is the fact that you need to use milk to produce milk kefir and a mixture of sugar and water to produce water kefir. Moreover, the grains used for these two beverages are different. There are water kefir grains and milk kefir grains available on the market nowadays, so make sure to get the ones you are insterested in.

Both of the drinks have a lot of probiotics. However, water kefir is considered to be a bit ‘lighter’ version. While milk kefir has a consistency of a liquid yogurt, water kefir will feel like you are having an ordinary soda.

Of course, the taste of the two differs as well. Milk kefir still tastes like milk, even though it has a more sour and sometimes even a tart flavor. The more you ferment the drink, the more carbonated it will turn out to be. Water kefir really does taste like soda. It is usually sweet and you can make it with a flavor of your choice.

How to Make Milk Kefir: Ultimate Step by Step Guide

Now, we are finally ready to share the actual milk kefir making recipe. Nothing too difficult, so don’t worry. Moreover, you can totally change the recipe after some time to find what works better for you. However, we would recommend sticking to the instructions for at least the first few batches, just to make sure that you master the basics.

Step 1: Grab your milk of choice and the milk kefir grains (about a tablespoon or two). Remember to use milk kefir grains. By the way, make sure that the little fellows are active as they can come dehydrated.


Step 2: You will need a special container in which you are going to place the ingredients. A glass jar would do perfectly well.


Step 3: Pour around 4 cups of milk into the jar and carefully place the milk kefir grains inside.


Step 4: Cover the container with a suitable cloth or a coffee filter. And don’t forget to secure the thing with the help of a rubber band, for example, to ensure that no fruit flies get inside the container.


Step 5: The fermenting milk kefir likes warm temperatures. So, you would have to place the container with the grains and milk in a safe spot with a steady temperature. Make sure that it’s not higher than 28 °C and not lower than 20 °C. If you want to take the kefir making process to the next level, then you can buy a thermometer to be able to monitor the temperature. The warmer the temperature, the faster the fermentation process goes.


Step 6: The process will take around 24 hours. In case it’s a little cooler in the room, the fermentation might take longer and vice versa. Check your future kefir to make sure that it has thickened and that the smell is pleasant. If you want to go the extra mile, get a pH tester. This device will help you ensure that the kefir is safe and that the beverage is acidic enough.


Step 7: After you feel like the process is complete, separate the precious grains from the drink and store them for later use. You might find it easier to separate the grains from the liquid with the help of a strainer. A wooden spoon is another instrument that you can use not only to stir the beverage, but to also help the liquid through the strainer. Simply remember to be gentle with the grains.


Step 8: Your milk kefir is ready! Now, you simply need to pour the beverage in the storage containers or drink it straight away. Bottles are, possibly, the most convenient vessels for storage.


Step 9: Put your kefir in the fridge in order to have a refreshing, healthy drink whenever you feel like it.

  • How to Add Various Flavorings to Your Milk Kefir?

Plain milk kefir has a unique taste. Usually, it’s sour or even tart. In case you want to add your favorite flavors to the kefir, you can totally do that during the second fermentation.

Simply make sure that the hands are clean, but, at the same time, don’t use any anti-bacterial soap as it might harm the grains. Moreover, this way might not be the fastest and the easiest one, as the little lads are slippery.

You can pour the kefir in a shallow bowl from the fermenting container. In such a way, you will be able to vividly see the grains and get them out with the help of a spoon or any other tool.

However, the majority of experts finds that it is better to use a strainer to separate the grains from the actual kefir. Simply pour the kefir in a strainer that you put over a bowl or a vessel with a wide mouth. Sometimes the kefir may turn out a bit too thick and you might find that it’s hard to get the liquid through the strainer. Don’t be afraid to use a wooden spoon, for example, to help the kefir through the holes. Just always remember to be careful with the actual grains.

What can you do, if you don’t need that much kefir? Can you put your grains ‘on pause’?

How to Store Water Kefir Grains_

Actually, you can. But there is one important rule: you need to culture the grains for at least three or four weeks before starting to use one of these ‘pause’ methods.

The best way to slow down the fermentation process is to cool down the kefir grains. The culturing will not stop, however, you will have a little more time between the batches, so that you have a chance to drink all the previous kefir.

But if you want to stop the kefir making process for at least a week or two or even more, then refrigerating the kefir grains might help. Leave the little guys in milk (don’t forget to tightly cover the storage vessel). The grains can live in your fridge for quite a while, just remember to change the milk at least every week.

Once you feel like you are ready to start making milk kefir again, you can put the grains with the milk in a warm place to stimulate the tiny fellows to culture actively as before.
