DIY Coconut Water Kefir: A Beginner's Guide to Fermented Drink Making

Coconut water kefir is a delightful and healthy drink that you can easily make at home. Not only does it add a refreshing touch to your diet, but it also comes with numerous health benefits. This article will guide you through the process of making coconut water kefir, from sourcing the right kefir grains to bottling the final product. Let's dive in!

Understanding Kefir Grains

Kefir grains are the live bacteria and yeast that allow for the fermentation process. There are two main types of kefir grains: milk kefir grains and water kefir grains. For making coconut water kefir, it is crucial to use water kefir grains, which are designed to consume cane sugar and naturally occurring fruit sugars.

Milk kefir grains, on the other hand, thrive on lactose, a sugar naturally found in milk. While both types resemble a gel-like substance, they are distinct organisms with different dietary needs. Water kefir grains are essential for this specific recipe since they require a sugar-based medium to thrive.

Step-by-Step Guide to Making Coconut Water Kefir

Step 1: Growing Your Batch

When starting out, it's important to build a strong and healthy batch of water kefir grains. Begin by purchasing 1/4 cup of sugar and adding it to a quart-sized mason jar. Fill the jar with enough hot filtered water to dissolve the sugar, stirring well until the sugar is fully blended.

Note: Ensure the water is not too hot, as this can harm the kefir grains. Once the sugar is dissolved, add some cold water to cool the liquid down. Place the kefir grains and any liquid they came with into the jar, ensuring the jar is full.

Important: Cover the jar with a cloth and secure it with a rubber band, not cheesecloth. The holes in cheesecloth are too large to protect against curious insects, and the cloth allows for proper air circulation. Store the jar away from light for 1-3 days.

Step 2: Observing Your Ferment

Over time, you will notice the liquid becoming less sweet and more sour, as the kefir grains consume the sugar. Taste the liquid daily to determine the speed of fermentation. Within 1-3 days, your kefir grains will have multiplied, roughly doubling in quantity.

Note: Fermentation speed is influenced by the ambient temperature. In warmer environments, the process happens faster, while in cooler environments, it slows down.

Step 3: Bottling and Second Fermentation

Once the liquid is slightly sweeter than desired, it is time to bottle the kefir. This second fermentation step is crucial for carbonation. Strain the kefir into a flip-top glass bottle or a jar with an airtight lid, leaving some headroom at the top. Seal it tightly and let it sit at room temperature for 1-2 days. During this time, the kefir will become fizzy.

Tip: The fermentation process can be vigorous, so be cautious when opening the bottle. Check daily, and ensure the desired level of fizziness and decreased sweetness is achieved. Once complete, store the kefir in the fridge to enjoy.

Alternative Flavors: Leaving the kefir plain is fine, but you can experiment by adding fruit juices or other flavors during bottling. However, be cautious with highly acidic ingredients like lemon. Pineapple juice works well, and you can explore other fruits like blueberry or even add ginger for a spiced touch.

Step 4: Maintaining Your Kefir Grains

To keep your kefir grains healthy and thriving, it is essential to alternate between two jars: one in the refrigerator for replenishing the grains and one at room temperature for active fermentation. After each batch, transfer the grains to the replenishing jar with fresh sugar water.

Replenishing Jar: Add 1/3-1/2 cup of sugar to a quart-sized mason jar of water. This will provide the necessary nutrition for the grains. When you strain your coconut water kefir, place the grains back into this jar, where they will remain until the next batch. The jar should be covered with a lid, as the grains need sugar to survive.

Coconut Water Fermentation Jar: Transfer the grains from the replenishing jar into a clean mason jar, enough to cover the bottom. Fill the jar with coconut water, cover with a cloth, and let it ferment for 1-3 days, tasting daily to determine the desired flavor.

Step 5: Long-term Care of Kefir Grains

Occasionally, you can feed your grains additional minerals by adding a tiny amount of molasses, a few raisins, or a pinch of baking soda. For backup, store a small portion of your grains in a jar of sugar water in the fridge, with a lid. Periodically, you will need to refresh their sugar supply to keep them happy and healthy.

Conclusion

Coconut water kefir is a fun and rewarding project for beginners in fermentation. By following these steps, you can enjoy a delicious, natural, and probiotic-rich drink. Don't hesitate to experiment with different flavors and variations to find your perfect taste. Enjoy your homemade coconut water kefir!

Happy fermenting!
