Creating new batches of water kefir is a fun experiment! You can play with different flavours and enjoy a delicious probiotic drink. However, the cycle of constantly making new batches can become overwhelming, prompting a need for a break. This raises a common dilemma: What do you do with your leftover water kefir grains? Don't throw them away just yet; you can easily store them for future use.
This blog will guide you on how to store water kefir grains. Whether you're on a short intermission or a longer hiatus, proper storage ensures that your grains remain healthy and active for your next batch. So, get ready to save yourself the trouble and expense of acquiring new grains later with a few practical storage tips!
What are water kefir grains?
Water kefir grains are the magical ingredient that transforms simple sugar water into the effervescent probiotic beverage you know and love as water kefir. They're not actually grains in the traditional sense but rather a symbiotic culture of bacteria and yeast.
These fascinating grains appear as small, gelatinous clumps reminiscent of tiny crystals. They're translucent and pick up colour depending on the specific sugar and fruit used during fermentation, ranging from clear white to opaque yellow or dark brown. Their texture is generally bouncy and slippery and can vary greatly in size, from rice-sized to as large as two inches.
When water kefir grains are introduced to a sugar-water solution, they kickstart the fermentation process, which produces organic acids like lactic acid and carbon dioxide. These compounds contribute to the water kefir's bubbly texture and slightly tart flavour. Moreover, the microorganisms in water kefir grains contribute to gut health, making them a beloved choice for those who seek probiotic-rich foods and beverages.
The fermentation process is short, typically taking about 24-48 hours. Once fermented, the water kefir is strained, and you have those precious grains in your hand. What do you do with them? Well, you can reuse them to make the next batch of kefir or save them for later use.

Next, let's explore the best methods for storing water kefir grains!
How to store water kefir grains when not in use?
Now that you do not intend to use the leftover water kefir grains immediately, you might look for ideal storage options. These grains are live cultures that must be stowed neatly to keep them happy and healthy for future fermentations. Depending on when you plan to make your next batch, you can consider the following storage methods.
Refrigeration
Refrigeration is the most common and convenient method for storing water kefir grains for the short term. If you plan to take a break from making water kefir, maybe for a few weeks or a couple of months, you can refrigerate the grains, which can typically remain viable for up to three months.
Here's a detailed step-by-step guide on how you can store water kefir grains using the refrigeration method:
-
Prepare the storage solution: Dissolve a small amount of sugar (about 1 tablespoon per cup of water) in filtered water. Allow the solution to cool completely before adding the grains.
-
Store the grains: Once cooled, transfer the sugar solution to a clean glass jar and add the grains. Cover the jar with a breathable cloth or a loose-fitting lid, and place it in the fridge.
-
Maintain the solution: Change the sugar water every week to ensure the viability of the grains.
Freezing
If you plan to store grains for a longer period, freezing is your best option. Frozen water kefir grains remain intact for up to six months. However, freezing can cause the grains to expand, which may slightly damage their structure.
Here's how you can freeze water kefir grains for later use:
-
Prepare the grains: Rinse the grains thoroughly with unchlorinated water and gently pat them dry with a clean cloth.
-
Store in the freezer: Place the dried grains in a clean, food-grade freezer bag, ensuring all the air is expelled before sealing.
Drying
Do you not plan to use your grains anytime soon? Drying is an option for longer-term storage, potentially up to a year. However, this method may not be suitable for all strains of kefir grains. Some strains may not survive the drying process.
Learn how to store water kefir grains using the drying method:
-
Prepare the grains: Rinse the grains with unchlorinated water and shake them in a strainer to remove excess water.
-
Air-dry the grains: Lay the grains in a single layer on a clean, nonstick surface (such as a baking sheet lined with parchment paper). Using a fan, gently circulate air around the grains to speed up the drying process.
-
Store at room temperature: Store the dried grains in an airtight container in a cool, dark, and dry place at room temperature for up to 1 month.
-
Long-term storage: For longer storage (up to 6 months), refrigerate the dried grains in an airtight container. Alternatively, you can freeze them for up to 1 year to preserve them longer.

How to reactivate stored water kefir grains?
Reactivating water kefir grains after storage requires a little patience as they emerge from their dormant state. Whether your grains were refrigerated, frozen, or dried, each method requires a unique approach to bringing them back to life.
-
Refrigerated grains: Start by separating the grains from the storage liquid and gently rinsing them to remove any 'pickled' residue, especially if they've been resting for over two months. Once cleaned, you can place the grains into fresh sugar water designed to match their activity level.
-
Frozen grains: Gently thaw the grains in the refrigerator to prevent shock from sudden temperature shifts. Once thawed, cleanse them using non-chlorinated water to eliminate any icy residue. Then, introduce the grains to sugar water and allow them to ferment as usual. Initially, you may notice a slight reduction in their activity, but they should quickly regain their vigour.
-
Dried grains: Rehydrating dried grains tests one's patience the most. First, soak the grains in plain, non-chlorinated water for 2-4 hours, allowing them to regain their original form. Then, transfer them to sugar water and observe their fermentation over several cycles.
Be ready for a journey of about 3-10 days before achieving consistent, quality kefir production. Keep an eye on the fermentation, looking for cues like bubbles and a tangy smell, adjusting the sugar-water ratio as the grains begin to gain momentum.

So, your grains are back in action, but are you still confused about choosing the right storage method? Let's break it down!
Which storage method should you choose?
Choosing the right storage method depends on your needs and how long you plan to store your water kefir grains. By experimenting and observing your grains, you can tailor a method that efficiently suits your lifestyle.
-
Refrigeration: This is the most convenient and generally the safest method for short-term storage. It's easy to maintain and minimises the risk of significant damage to the grains.
-
Freezing: While suitable for long-term storage, freezing can cause some minor damage to the grains due to ice crystal formation. This may slightly reduce their activity, but they usually recover after a few batches.
-
Drying: Drying is the most challenging method and may not be suitable for all strains of kefir grains. The drying process can sometimes damage the delicate balance of microorganisms within the grains, potentially reducing their viability.
If you want an alternate beverage to water kefir that offers the same benefits but with more fizz and tanginess, try kombucha.
