What is water kefir?
Water kefir is a captivating fermented beverage favoured by many for its unique qualities and health benefits. It is made by culturing sugar water with water kefir grains. These grains are not actual grains but a symbiotic culture of bacteria and yeast. These gelatinous, crystal-like structures work together to ferment the sugars, bringing water kefir to life.
The fermentation process imparts water kefir with its characteristic fizz and taste. It typically exhibits a subtle sweetness from the sugar, balanced by a refreshing tartness that develops during fermentation. You'll also notice a slight effervescence due to the natural carbonation produced by the microorganisms.
While its unique taste and texture certainly contribute to its appeal, water kefir's popularity extends far beyond its flavour. Let's explore why this refreshing beverage has captured the hearts of many:
-
Rich in probiotics, it supports gut health and digestion.
-
Unlike milk kefir, water kefir is dairy-free, making it an excellent choice for those with lactose intolerance or specific dietary preferences.
-
It is abundant in vitamins and minerals, such as B vitamins and calcium, contributing to overall health and well-being.
-
Water kefir also stands out due to its versatility in flavouring—you can add fruits, herbs, or spices. This adaptability makes it easy to accommodate various taste preferences.
-
It is low in calories and sugar content, providing a healthier alternative to sugary drinks.

Making your own water kefir at home
While enjoying a refreshing bottle of store-bought water kefir is certainly convenient, there's a unique satisfaction in crafting your own. Making water kefir at home is surprisingly easy and requires only a few simple ingredients:
-
Water kefir grains: Small translucent crystal-like grains that can be bought from a store.
-
Sugar: Typically, cane sugar or organic sugar is used.
-
Water: Filtered or spring water is recommended.
-
Additional flavourings: Fruit juices, herbs, or spices are added for extra flavour.
Here’s a detailed step-by-step guide to making water kefir at home:
-
Start by dissolving ¼ cup sugar in 1 cup of water to create a sugar-water mixture.
-
Allow the sugar-water solution to cool before transferring it into a jar.
-
Add 2 tbsp of water kefir grains into the jar and mix well.
-
Fill the rest of the jar with filtered water.
-
Cover the jar with a breathable cloth.
-
Keep it in a cool, dark place at room temperature and let it ferment for 24-48 hours.
-
Once the mixture ferments, strain the liquid and remove water kefir grains, which you can reuse for the next batch.
-
Bottle the strained water kefir and add fruits, herbs, or spices such as ginger, mint, or berries.
-
Seal the bottle and leave it undisturbed for 1-2 days to infuse the flavours.
-
Uncork the bottle, gather your friends, and enjoy!

How do you store water kefir?
Once you have crafted your flavourful batch of water kefir, preserving its quality takes center stage. A common query arises: Can you keep water kefir at room temperature and sip away at your leisure? While tempting, leaving it at room temperature beyond the fermentation process is not recommended, as it tends to spoil rapidly due to increased microbial activity.
-
Transfer to glass bottles: Once you achieve your desired taste, transfer your water kefir into glass bottles or mason jars with airtight lids. These containers can prevent contamination and keep your drink bubbly. However, remember to burp the bottles by opening the cap slightly to release built-up pressure that may break the containers.
-
Refrigerate: After bottling your water kefir, it’s best to refrigerate it. Refrigeration helps preserve its freshness and probiotic activity. Cold temperatures significantly slow down the fermentation process, preventing the beverage from turning into vinegar, thus extending its shelf life.
But how long can you keep your water kefir refrigerated?

How many days can water kefir last in the fridge?
Do you remember how your two-day-old curry became spoiled despite being kept in the refrigerator? Likewise, does storing water kefir in the fridge come with a time stamp? How do you know when it goes bad? Whether homemade or store-bought, understanding its shelf life is key to enjoying water kefir.
-
Homemade kefir: If you plan to consume your homemade water kefir within four days of making it, you don't have to refrigerate it. However, it's best to keep it chilled if you can't finish it within this time frame. Once opened, homemade water kefir will typically last about ten days in the fridge. On the other hand, unopened bottles can stay good for up to three weeks.
-
Store-bought kefir: For store-bought kefir, it's wise to follow the 'best before' date on the bottle. Generally, it can last 1-2 weeks in the refrigerator if opened.
Always trust your senses. If you notice any strange smells, changes in texture, or signs of mould, discard your batch. This will ensure the taste and safety of your water kefir.
But what influences this delicate balance? Let’s investigate the factors affecting that precious shelf life.
Factors affecting water kefir’s shelf life and quality
While refrigeration can extend the shelf life of your water kefir, it's important to remember that it's not a static entity. Even within the confines of your refrigerator, certain factors can influence how long it remains fresh and enjoyable:
-
Live cultures: Water kefir is alive with active cultures that continue to consume sugars in the kefir, even in the refrigerator. Although this fermentation slows down in a cold environment, it does not completely halt, gradually transforming your refreshing drink into a vinegar-like liquid.
This is a natural result of the fermentation journey. You can embrace this change by using the resulting vinegar as a healthy alternative to commercial vinegar. Not only is it rich in probiotics, but also contains beneficial vitamins and minerals.
-
Flavourings: Flavouring your water kefir with fruits can further impact its shelf life due to the presence of added sugars. This increased sugar content can provide fuel for the live cultures, thus accelerating the fermentation process and potentially shortening the shelf life of the flavoured water kefir.
For instance, a cherry-flavoured kefir might become vinegary faster than a less sugary option like lemon. So, it is a good practice to regularly check the taste and smell of your flavoured water kefir.
With these insights in mind, let's explore some pro tips for storing it just right!
Tips for storing and caring for your water kefir
How you store your water kefir can make a world of difference in whether it tastes refreshingly crisp or unpleasantly vinegary. Here are a few tips to ensure you store your water kefir properly:
-
Maintain consistent temperature: Temperature fluctuations can lead to unwanted microbial growth and speed up fermentation, which might spoil the taste and reduce the probiotic benefits of the drink. Ideally, keep your fridge at a stable temperature between 40°F and 50°F (4°C to 10°C) to preserve the freshness and active cultures in your kefir.
-
Check for signs of spoilage: Inspect your water kefir regularly for signs of spoilage, such as unusual mould growth, off-odours (resembling vinegar or alcohol), or excessive carbonation. These signs indicate that it's time to discard the batch to avoid health risks.
-
Ensure proper cleaning and sanitation: Wash and rinse your storage containers thoroughly and sterilise them before bottling water kefir. Avoid using metal utensils, as they can react with the acidic environment of kefir. This will help ensure the quality and safety of your kefir.
-
Consume within the recommended timeframe: Consume your water kefir within the recommended shelf life of 1-2 weeks to enjoy its optimal flavour and probiotic benefits.
Water kefir is a truly delightful probiotic beverage that can be enjoyed chilled on a hot summer day. Now that you know how many days water kefir can last in the fridge, don’t hesitate to stock up on this refreshing drink. Follow these simple tips and ensure that it remains fresh, flavourful, and brimming with beneficial microorganisms.
Don't be afraid to experiment with different flavours. Whether you prefer the classic tanginess or enjoy the infusion of fruits and herbs, a water kefir experience is waiting for you.
