Have you been a devoted lover of the creamy, tangy goodness of milk kefir? Yet, do you find yourself yearning for something different—a lighter, more refreshing sip that still offers those incredible probiotic benefits? Maybe it's time for you to make the switch to water kefir! But here's the dilemma: You only have milk kefir grains. Can you use them to make water kefir?
Many of you want to try water kefir but hesitate at the thought of discarding your existing milk kefir grains. Fortunately, you do not have to let go of those precious grains. This blog will teach you how to convert milk kefir grains into water kefir grains. Let's embark on this fermentation adventure and enjoy the probiotic benefits of both worlds!
Milk kefir vs. water kefir
At its core, kefir is a fermented beverage made by introducing kefir grains—a symbiotic culture of bacteria and yeast—to a liquid medium. These grains then work their magic, transforming the liquid into a tangy, probiotic-rich drink. You'll find kefir in various forms, with milk kefir and water kefir being two popular choices.
-
Milk kefir: As the name suggests, milk kefir is produced by culturing milk with kefir grains that resemble small cauliflower florets. This fermentation process results in a creamy, tangy beverage teeming with probiotics. Being a dairy product, milk kefir is a substantial source of protein, calcium, and other essential nutrients that contribute to gut health.
-
Water kefir: Water kefir stands out as a fermented beverage crafted by cultivating sugar water with its unique set of kefir grains. These grains are smaller and translucent, thriving in a sugar-water environment to produce a lightly sweet, effervescent drink. As water kefir is completely dairy-free, it is suitable for lactose-intolerant people. You can also customise it with various fruit and herbal flavours during a secondary fermentation phase.
The key differences between these two probiotic drinks lie in their fermentation agents and nutritional profiles. While milk kefir resembles yoghurt or buttermilk in texture and flavour, water kefir is lighter and offers a different sensory experience. Both milk and water kefir contribute to gut health, and the choice depends on dietary preferences and tolerances.

Can you use milk kefir grains to make water kefir?
While milk kefir grains are primarily adapted to fermenting milk, they can also be transformed into water kefir grains to ferment sugar water. This transition involves guiding the microbial community within the grains to thrive in a new environment.
The science behind this conversion lies in the adaptability of the microorganisms within the kefir grains. These microorganisms possess a degree of metabolic flexibility, allowing some to use sugars from the environment for growth and fermentation. However, the success of this adaptation can vary significantly depending on the specific strains of bacteria and yeast present within the milk kefir grains. Some strains may readily adapt to the new environment, while others may struggle or even become dormant.
Now that you know you can use milk kefir grains to make water kefir, let's see how it's actually done!
How to convert milk kefir grains to water kefir grains?
Are you excited about embarking on the journey of making water kefir? While you can use milk kefir grains to make water kefir, the transition requires a bit of patience and a gentle nudge in the right direction. Here's a step-by-step guide to help you through the process:
Step 1: Preparation of milk kefir grains
Before embarking on this conversion journey, it's crucial to ensure your milk kefir grains are robust and thriving. This preparation phase will help them adapt more smoothly to their new environment.
-
Activate the grains: Ensure your milk kefir grains are fully active and rehydrated. Ferment 1 cup of whole milk with the grains for 24 hours. Repeat this process for three consecutive days, allowing the grains to actively ferment the milk and regain their vitality.
-
Thorough cleaning: After each fermentation cycle, strain the milk and thoroughly rinse the grains with cool, filtered water to remove any residual milk residue. This ensures a clean transition and prevents any lingering milk components from interfering with the water kefir fermentation process.
Step 2: Creating the sugar-water solution
Now, let's prepare the ideal environment for your transitioning grains.
-
Prepare the solution: Dissolve ¼ cup of unrefined cane sugar in 1 quart (quarter of a gallon) of filtered water. This creates the sugar-water solution that will serve as the foundation for your future water kefir.
-
Add minerals: To ensure a healthy environment for the microorganisms, add ⅛ teaspoon of unrefined sea salt to the solution. This provides essential minerals for their growth and activity. Optionally, add ½ teaspoon of molasses for additional mineral content. Molasses is a rich source of trace minerals that can further support the transition process.
Step 3: Introducing the grains
Once the sugar-water solution is prepared, it's time to introduce the milk kefir grains to their new environment.
-
Initial fermentation: Add the activated milk kefir grains to the prepared sugar-water solution. Cover the jar with a breathable cloth or coffee filter and secure it with a rubber band.
-
Fermentation time: Allow the mixture to ferment for 4-5 days at room temperature (around 70-75°F or 21-24°C).
Step 4: Making gradual adaptation
This is where the real magic happens—the gradual adaptation of the milk kefir grains to their new role as water kefir producers. This stage requires patience and careful observation as you guide the grains toward their new environment.
-
Reduce fermentation time: After the initial fermentation, carefully separate the grains from the fermented liquid. Prepare a fresh batch of sugar-water solution and add the grains. Gradually reduce the fermentation time by 12-24 hours with each subsequent batch until the culturing period is 48 hours or less. This allows the grains to adjust to the new environment at their own pace.
-
Observe and adjust: Throughout this process, closely observe the fermentation activity. Monitor the behaviour of the grains, the flavour and aroma of the fermented liquid, and the level of effervescence. If the liquid is overly sour or the grains seem sluggish, slightly increase the fermentation time. If the liquid is too sweet or the grains appear overly active, shorten the fermentation time.
Step 5: Confirming successful conversion
After you gradually reduce the milk content, your grains should ferment in 48 hours or less. This time frame is the hallmark of successful conversion from milk to water kefir grains. Consistent fermentation within this period indicates that your grains have adjusted well to the sugar-water environment.
Look for signs that the grains have successfully adapted to the new environment, such as vigorous fermentation activity, a slightly effervescent liquid, and the development of a subtle, tangy flavour.
Step 6: Post conversion: Making water kefir
Now that your grains have been successfully converted, you can use them just like regular water kefir grains. Combine them with a fresh sugar-water solution and let them ferment for 24-48 hours per batch. This routine fermentation will consistently yield a tasty, probiotic-rich beverage.

Things to consider while converting milk kefir grains
Converting milk kefir grains to water kefir grains can be complex. While the process outlined above provides a solid foundation, it's important to remember that every batch, every set of grains, and every environment is unique. Here are a few important things to consider as you use milk kefir grains to make water kefir:
-
Patience and persistence: It's crucial to approach this conversion with patience and persistence. Don't get discouraged if the initial attempts don't yield the desired results. It may take several batches for the grains to fully adapt to their new role.
-
Irreversibility: Once milk kefir grains have adapted to the water kefir environment, they cannot revert to milk kefir grains. This is a permanent change, so it's wise to save additional sets of grains to keep making your beloved milk kefir. Consider these your 'insurance policy' against the unpredictability of conversion.
-
Environmental factors: The success of the conversion can be influenced by various environmental factors, such as temperature fluctuations, air quality, and even the mineral content of the water used.
For grains to thrive, they need to be in a controlled environment with temperatures ideally between 68°F and 78°F. Mineral-rich water paired with unrefined sugars provides the nutrients necessary for the grains to adapt.
The transformation of milk kefir grains to water kefir grains might seem daunting at first, but with patience and practice, it is entirely achievable. By adopting this method, you can open the doors to a refreshing and healthful world of water kefir, packed with probiotics that contribute positively to your well-being.
Embrace the challenge with a spirit of experimentation and learning. Trying out different sugar concentrations and fermentation durations allows you to discover what works best for your grains and, ultimately, what produces the most delightful beverage for your taste buds.
