Water kefir is the easiest way that I’ve found to make sure that my children get enough probiotics. It is a naturally fizzy and mildly sweet drink that is created when the grains (not actual grains, but a symbiotic colony of yeast and bacteria) interact with the natural sugars in the water to create probiotics and enzymes.
The finished water kefir can be flavored in a secondary ferment with juice, ginger root, fruit, or other natural substances and this step creates natural carbonation (and a similarity to soda).
Water kefir can also be brewed with coconut water which is naturally high in electrolytes, enzymes, and nutrients. This is brewed exactly like water kefir, though the sugar can be reduced to 25% because coconut water is naturally sweet.

Coconut Water Kefir Recipe
- ¼ cup sugar optional
- 4 cups coconut water
- ¼ cup water kefir grains (hyrated)
- Add the sugar to a half gallon glass jar, if using.
- Add the coconut water to the jar.
- Stir thoroughly to dissolve the sugar.
- Add the hydrated kefir grains to the sweetened coconut water.
- Cover the jar with a plastic lid, cloth cover secured with a rubber band, or fermentation cap.
- Let sit in a warm place (70-78°F) for 24-48 hours to ferment.
- If the sugar is omitted, taste it after 24 hours. If using the sugar, allow for 48 hours. It should taste like tangy coconut water.
- Strain out the kefir grains with a cheesecloth or non-metal strainer. The grains can be used to immediately start another batch of water or coconut water kefir.
- Once the grains are removed, you may add flavors for a second fermentation or drink plain. See notes for a link to flavor options and instructions for a second ferment.
- Store the finished product in the refrigerator and enjoy chilled!
Coconut Water Kefir FAQs:
Is this different than regular water kefir?
Coconut water kefir is a simple adaptation of water kefir – instead of water, we use coconut water along with a reduced amount of sugar to make a bubbly, hydrating, digestion boosting beverage. Some prefer to omit all of the sugar, and those drinking coconut water kefir for a candida cleanse should leave it out, but we recommend using 25% sugar for the best flavor.
Can you still flavor it?
Yes! Coconut water kefir has a delicious natural tang that many people enjoy on its own. Of course, any number of fruits, herbs, and spices may also be added for additional benefit and to create unique flavors. Try a little lemon and ginger or maybe a few cut up strawberries to start, then let your imagination run wild from there!
Does fermentation affect the nutrients in the coconut water?
Coconut water is incredibly nutritious — here is a short list of some of what it provides:
- electrolytes – replenish the body
- cytokinins – phytohormones that promote healthy cell functioning (anti-aging, anti-carcinogenic)
- amino acids – building blocks
- enzymes – help with digestion and metabolism
- mineral rich – calcium, iron, manganese, magnesium, potassium, and zinc
- B-vitamins – essential and in a living form
Fermentation applies healthy bacteria and yeast to the substrate (in this case coconut water) and acts like the first step in the digestion process by breaking down all of these elements into an easier to absorb form making them bioavailable.
Nutrition in a living form often takes a different shape (chemical structure) than its chemicalized form (found in supplements, added to food, or in pill form). So when the body receives nutrition in the shape that it has evolved to recognize, uptake of that nutrition happens seamlessly.
Chemicalized nutrition may not have the exact same chemical structure which means it may have to be used differently or it may not be absorbed at all depending on how the body “interprets” the shape. (This is also one of the reasons why consuming GMO’s is also so harmful; the body doesn’t recognize the GMO and creates an autoimmune response to it thinking its an invader — which of course, it is.)
Fermentation is the ultimate enhancer. It makes nutrition easier to absorb thus aiding the body in repair and maintenance at all levels.
Do you have to use pure coconut water since it is more expensive?
Coconut water kefir may seem like a luxury due to the high cost or limited availability of coconuts in any particular region. For those who need the additional nutrition, it can be well worth the expense and far less costly than other supplements or pharmaceutical treatments. Coconut water also comes in many different forms including frozen, in tetrapaks, or fresh. We have taste tested and found that fresh coconut water tastes best fresh and frozen or tetrapak coconut water tastes better as kefir.
Those wanting the benefit on a budget may dilute coconut water by half to stretch it longer. If that is the case, then use 50% of the sugar called for in the recipe. The good thing is that the kefir grains, once they get going, will continue to perpetuate themselves indefinitely.
IMPORTANT TIP – Resting the grains
Coconut water kefir, while delicious, does not provide the appropriate environment for kefir grains to reproduce. In order to keep the grains going, we recommend resting them every few batches in sugar water. If you notice that the grains are receding or change shape (less crystalline), that is a sign that they need to be rested.

How long does the kefir keep in the refrigerator once the fermentation is done?

I’ve never tested it past a couple weeks, as my family drinks it too quickly!
Thanks for sharing this recipe! In step 7 you state:
“Coconut water kefir is like tangy coconut water. If the sugar is omitted, taste it after 24 hours. If using the ¼ cup of sugar. If you prefer a tangier brew, the water kefir may be 2F to yield a deeper flavor. Once the grains are removed, you may add flavors for a second fermentation or drink straight”.
What do you mean by ” the water kefir may be 2F to yield a deeper flavor”? Would you please clarify this?
How do you do a second fermentation? Thanks!
How many probiotics would you say is in this recipe?
I’d love to try this, but I have a few questions. In step #7 of the recipe, it states, “If using the ¼ cup of sugar.” Something seems missing here. There is an “if” statement, but no “then” statement. The next sentence states, “If you prefer a tangier brew, the water kefir may be 2F to yield a deeper flavor.” I don’t understand what “2F” means. Finally, the directions say, “Once the grains are removed…,” but it doesn’t say how to remove them. What do you do with the grains? How do you keep the? What is meant by “resting” the grains? To add flavors, do you add whole fruit, juice, or something else? And, what is a second fermentation? Do you just recover the jar and let it sit for another 24-48 hours? Would this be without the WT grains this second time? Does it sit at room temp or refrigerated? I guess that’s more than a few questions….sorry. Thanks for any clarification you can provide.
you don’t need a then after an if statement. if the sugar is omitted, taste it after 24 hours. you don’t need the then before taste. it’s implied.
“1. Add 1?4 cup of sugar to the jar, if using.” Just reverse this in your head: If using the 1/4 cup of sugar, then add it to the jar. It just means you don’t necessarily have to add the sugar if you don’t want to.
7. you remove the grains in step 7. after they are removed you can add flavours and do a second ferment.
Can I get the Coconut Water Kefir at a health food store locally? Is it safe for little ones?
I have not seen it in stores, but you could look for it near you. And I let my kids drink mine… they really enjoy it!
Yes you can buy coconut water kefir at whole foods or other organic a groceries. The brand is called KeVita, they have many awesome flavor a but mine is the coconut & lemon ginger
It’s a bummer they have other additives in there. I almost bought one today but wasn’t fond of the added ingredients like “natural coconut flavor” and stevia. I wish they would make a plain one and we could add our own flavoring. I’m just going to have to make my own 🙂
Kevita is not made with coconut water.
I have been wanting to try this for so long. The only issue I have is the sugar. I want to make it without it. Is there any further info on not using it? She said to taste after 24hrs. We love coconut water and my kids want to make coconut soda, they do not like regular soda. Thank you for all your help :).

The sugar is needed for the formation of the probiotics and enzymes but is mostly fermented out
I have a question kind of unrelated, will adding DE to any probiotic drink alter health benefits or kill the bacteria?
It might… I’d keep them separate
For the second fermentation how long do I let the fruit stay in the coconut kefir water?
Hi katty, what exactly water kefir taste. I am making my own, but I am not sure if I making right. I did a second fermentation, but it is not carbonated.
I’m having the same problem. No carbonation.
When second fermenting, you have to make the environment anaerobic so you need an oxygen proof jar
Does coconut sugar or maple work with these or does it need to be a white sugar?
NOOOOOO! Coconut sugar makes the water end up smelling like vomit!
Is the sugar necessary? White sugar is highly refined and not good for the body in many articles I have read. Organic does eliminate GMOs, but it is still processed.
Thanks so much.
The Kefir is sensitive and require a specific environment to live in; unfortunately, the more ingredients in the sugar, the harder it is for the Kefir to live.
“Choosing a Sugar for Making Water Kefir
When choosing a sugar for making water kefir, always read the label. Some sugars may contain anit-caking additives or other ingredients that could affect the health of the water kefir grains. Look for plain sugar with no added ingredients, for best results.” – from https://www.culturesforhealth.com/learn/water-kefir/water-kefir-ingredients/
