Kefir Jars: 5 Best Jars for Making Kefir to Buy

During the last few years, kefir has become an extremely popular product. And that’s amazing! Because now we know about the unbelievable nutritious value of this beverage and we can use it to our advantage.

Moreover, we have figured out that it is not only possible to make water or milk kefir at home, it is also easy and fun to produce it. In case you have the right equipment, of course.

And when it comes to the kefir making equipment, jars are, possibly, the most important part of the required kitchenware. You can use these containers to ferment your kefir and even to store it in your fridge later on.

But there are so many different options out there… How can you find out which jar is suitable for you?

Don’t worry, we have come up with a simple list of the 5 best jars for making kefir:

1. 1 Gallon Glass Jar with Plastic Airtight Lid

2. Bormioli Rocco Clean Fido Glass Storage Jar

3. Bormioli Rocco Fido Clear Jar

4. Home Brew Ohio One Gallon Wide Mouth Jar

5. Anchor Hocking Heritage Hill Glass Storage Jar

Make sure to read the description to the containers carefully. But before we proceed to the actual characteristics of the best jars for making kefir, let’s find out a little more about what size you should pick. What material should the jar be made of? And what are the other things that you have to pay some extra attention to when choosing a jar for your kefir?

What Are the Suitable Materials for the Containers for Making Kefir?

It is important to understand that your milk or water kefir will be spending quite some time in the jar. And if the spoons and strainers can be made out of practically any material (because they interact with the actual kefir only for half a minute or so), the container has to be chosen wisely.

Plastic, for example, can be used for kefir making. However, even food-grade plastic is not recommended as it’s the kind of material that can easily get scratched. These scratches can become the perfect ‘home’ for various pathogenic bacteria that will ruin your kefir grains.

When it comes to metal, you can try using containers made out of stainless steel, but be very careful and make sure that the container is of amazing quality. All the other metals can react with the kefir and that can be dangerous not only for the grains but also for your own health.

Why crystal jars are not suitable for kefir making? The truth is that this material contains lead and it can easily end up in your water or milk kefir. And we don’t want that to happen, right?

You can use ceramic or porcelain containers for kefir making. Ensure that the glaze is food-grade and that there are no small pieces.

However, the best material out there for the containers for making kefir is, without a doubt, glass. It is a non-reactive material. In most of the cases, it is transparent, so you will be able to see what’s going on with your baby kefir. And last but not least, it’s a relatively cheap material that you can easily find on the market.

What Is the Perfect Size of a Jar for Making Kefir?

The jars come in absolutely different sizes. And sometimes it might be a bit difficult to choose the right one. Especially, if you are just getting started. The main question that you have to ask yourself is how much kefir you want to be consuming daily? Once you take the length of the fermentation cycle into consideration, it will be much easier to define the actual size of the jar.

  • 5-gallon jars are usually perfect for beginners. Or for those who don’t need a lot of kefir. In case you want to be drinking about two cups of this nutritious beverage every day, then a half of a gallon is the ideal size for you. Another important thing is that such containers can easily fit in the fridge, in case you don’t want to be buying a separate vessel for this purpose.


  • 1-gallon jars. With such a vessel, you will manage to get around two gallons of milk or water kefir every week. You can get even more if you are not going for the second fermentation. These containers are great, in case you have a small family that will be drinking kefir as well. However, you would have to invest in storage containers as such jars rarely fit someone’s fridge.


  • 5-2-gallon jars. These lads are huge and you will be able to make a lot of kefir with such jars. Make sure that you really do need such amounts of this drink.

What Should You Look for in an Ideal Jar for Making Kefir?

Some say that an ideal jar should have a wide opening. However, this is true for the individuals who are into cultured vegetables or kombucha, for example. A wide opening is not that important for kefir. When picking the form of your jar, simply think about which one would be more convenient for you to use.

Make sure that your jar has a lid, in case you want to use it to store your milk or water kefir. If you’re into second fermenting, then bear in mind that the lid has to be sealed.

Finally, you have to be able to see what is going on inside with your baby kefir. Just to make sure that the beverage is even and not too thick. So, transparent glass is the best choice.
