Bottling Kefir: 4 Best Bottles for Making Kefir to Buy

What can possibly be better than having some fresh, homemade kefir stored in your fridge? You can drink a glass of this cold beverage whenever you feel like it and you know that it will be incredibly beneficial for your overall health.

However, it is not always possible or convenient to store the water or milk kefir that you have just made right in the primary brewing container. Usually, it’s just too big. Or you might want to use it straight away for the next batch.

Bottles are an amazing solution for all the kefir makers out there. In fact, these vessels are, probably, the most efficient way of storing your beverage.

What are the best bottles for making kefir? What are the main factors that you have to take into consideration when buying the bottle and then storing the drink? Let’s find that out together!

How to Choose the Right Bottle?

Do you know the kefir that has been stored in the fridge for a while has a sweeter taste and appears to be less sour? Moreover, it is always nicer to have a sip of something cold. And what better way to do that than from a convenient bottle?

If you are into kefir production, you already know that the materials used play an incredibly important role. There are some specific types that you can’t use as it might be dangerous not only for the grains but also for your health. However, when it comes to bottles, there are a lot of safe materials to choose from. Glass options are a classic. But you can always find one made of food grade plastic or stainless steel. If you happen to come across a stoneware bottle, you can surely use this one to store your water or milk kefir as well. You want to make sure that the bottle is thick enough.

The great news is that you might not even have to invest in these bottles. The chances are high that you already have a few at home or your neighbors might have some. There has to be a lid that comes with the bottle. And if you are able to find an option with a swing top lid, things will become so much simpler (craft beers sometimes have such bottles). By the way, if you decide to use plastic vessels, make sure to store the kefir in them for only a few times. Milk kefir especially can be incredibly acidic. And the drink might end up simply ‘eating’ the bottle.

How to Bottle the Kefir?

There is nothing too difficult about the actual process.

Take a close look at the bottles. They shouldn’t have any cracks or defects as that may affect the quality of your drink. Storing the kefir in a bottle is also a great opportunity to add some flavors to the beverage. Before pouring the kefir in the bottle, add your desired flavor and only then carefully fill the bottle with your water or milk kefir.

One important thing. Make sure to leave around an inch of headspace.

You can leave the closed bottle at room temperature for up to three days for secondary fermentation. However, bear in mind that you would have to open the bottle every day to ensure that it does not explode because of the inside pressure. You can always store the bottle in the fridge right away. But you would still have to open the containers with some extra care as different accidents can occur.

How to Avoid Accidents?

Your kefir is a beverage with bubbles in it. And even though we all enjoy a carbonated drink from time to time, the bubbles can also become a problem (and turn your kitchen into a real mess). Bottles may explode due to a variety of reasons. The temperature, the flavorings, the number of grains you’ve added – everything can play a role. However, there are a few pieces of advice that can help you minimize the risk.

  • Use high-quality bottles – the vessel has to be thick and without any cracks. Some might want to use the cheap beer bottles simply because they might have a few at their place. Don’t do that as the thin glass can easily burst even in the fridge. Or (in the worst case scenario) in your hand, causing some injuries.


  • Find a place with lower temperatures – if you want to use the bottle for your second ferment, then make sure to store it in a cool place. Pay extra attention to your kefir during the hotter months.


  • Make the bottles burp – this might be the most effective preventative measure. Try opening the bottles at least once a day and then quickly close them. However, be careful and don’t open the bottles too many times or your kefir might lose the flavor and some healthy properties. As a rule of a thumb, if your bottle is ‘hissing’, then the time has come to help it ‘burp’.


  • Don’t add too much flavoring – especially, if the kefir is high in sugar.


  • Pour the kefir the right way – in case you are using a few bottles to store the kefir, you would want to make sure that the last few cups that are left from your fermentation are equally distributed among the bottles.
