How to Make Coconut Water Kefir

Water kefir can be secondary fermented with coconut water, to make coconut water kefir! It’s naturally high in electrolytes, enzymes, nutrients, and probiotics.

Unleashing the Power of Coconut Water with Kefir Grains

Coconut water kefir has a delightful tropical flavor and a bounty of health benefits. This version of water kefir utilizes coconut water’s natural sweetness and mineral richness. It is delicious and packs a nutrient-dense, probiotic punch.

Why Coconut Water?

Coconut water’s natural composition includes fermentable sugars like fructan and sorbitol, making it an excellent base for water kefir. The beneficial microbes in the kefir grains—like Lactobacillus brevis, Lactobacillus casei, and Saccharomyces cerevisiae—consume these sugars during fermentation. This process reduces the FODMAP content, making it easier to digest, and increases the nutrients’ bioavailability, transforming it into a gut-friendly, probiotic-rich drink.

Simple Steps to Make Coconut Water Kefir

Here are all the ingredients you need to make your coconut water kefir at home with minimal ingredients:

Ingredients:

  • Water kefir grains
  • Water and Sugar (for primary fermentation)
  • Pure, organic coconut water

Safety Note: Always verify that your fermentation bottles are designed to handle pressure. Recycled kombucha bottles are a great choice as they are made to withstand high carbonation levels.

Enjoying Your Coconut Water Kefir

The result after fermentation is a sparkling, lightly sweet, tangy beverage that is excellent for hydration and gut health. Coconut water kefir can be enjoyed independently or as a base for creative probiotic cocktails. Its high mineral content makes it particularly beneficial for replenishing electrolytes and supporting adrenal health.

How to Make Coconut Water Kefir

Water kefir can be secondary fermented with coconut water, which is naturally high in electrolytes, enzymes, and nutrients. When fermented, coconut water is easier to digest and contains more boiavailable vitamins and minerals.

  • Prep: 30 minutes
  • Total Time: 48 hours 30 minutes

Ingredients

  • about 3 cups fermented sugar water from primary fermentation
  • 3 cups organic coconut water

Instructions

  1. It is vital that you use carbonation-safe bottles for secondary fermentation. This recipe makes 6 cups, so I use three 16-ounce bottles. You can use fresh-pressed juice (see notes) or bottled pasteurized juice; both work great (ensure it’s 100% juice, no additives).
  2. Fill a carbonation safe bottle about 1/2 full with fermented sugar water from primary fermentation.
  3. Top off the bottle with the coconut water so there is about an inch of headspace left in the bottle.
  4. Secure the bottle lid and gently invert it a couple times to mix.
  5. Allow it to ferment at room temperature (70-80 degrees F) for about 24-48 hours.
  6. Carefully open the lid to see if it is carbonated to your liking. If it is refrigerate, if not continue to ferment for 24 more hours, carefully checking the carbonation again.
  7. Keep refrigerated.

Notes

  • If using fresh coconut water, I suggest heating it to 145° F for a few minutes and cooling it before using it. This ensures that no wild microbes get introduced into the water kefir.
  • The coconut water ratio is slightly adjustable. The best ratio for lower sugar is 3 parts fermented sugar water and 1 part coconut water. For slightly sweeter, as with this recipe, I do half fermented sugar water half coconut water.

    You mention leaving cheesecloth on the top, does a silicon fermentation lid work as well or is it best to use an open weave cloth?

      No, cheesecloth works best. There needs to be good airflow into the jar.

    Do you ever burp it during the second ferment? I’m so nervous about an explosion. 🙈

      Sometimes I do, especially if I include whole fruit pieces in the second ferment. You can burp it before refrigerating. Just be careful, don’t open it all at once, and do it over the sink.

      It should last a couple of weeks. It might get fizzier the longer you store it.

    I’m new to making water kefir and my last batch almost has a wine/alcohol flavor to it. It’s sour and not sweet at all anymore unlike my first batch. Is this normal? I’m really wanting to use this for my young kids and don’t want to be basically giving them alcohol if I have done something wrong 🤣

      If it smells like alcohol, that usually means you added a lot of sugar. more sugar = more alcohol. Did you use my recipe here? and did you use a kitchen scale to measure the ingredients?

Okay, fine, it’s not the only reason, but it’s Okay, fine, it’s not the only reason, but it’s a reaallllyy good reason to buy another pumpkin!

My new sourdough pumpkin bagel recipe is up on our blog!
https://cultured.guru

these roasted pumpkin bagels can be made savory or sweet! Both options are included in the recipe and are perfect for fall sourdough baking. 

The savory is a pumpkin, parmesan, onion (leek) flavor, and the sweet is a cinnamon brown sugar pumpkin flavor! ✨

You can also choose to use active starter or discard with yeast. It’s up to you! 

Let me know if you try baking these this weekend! 🍂🎃🥯

Google “golden beet kvass recipe” and you’ll Google “golden beet kvass recipe” and you’ll see mine, it’s the first one. 🫧✨

I only like to learn fermentation from two places: from knowing the microbes and from cultural recipes passed down in families.

I originally learned how to make kvass from a Russian food blogger, named Peter. @petersfoodadventures He grew up drinking beet kvass made by his grandfather. It doesn’t get more historically/culturally accurate than that

After learning from Peter’s blog, I developed my golden beet kvass recipe, with some slight variations of my own and a secondary fermentation to carbonate it. (Peter is credited and linked in the recipe blog too, so you can check out his original beet kvass recipe!)

Anyways, beet kvass is a delicious, sweet, bubbly beverage, not a salty lacto-ferment 🤗🫧✨

dont want to be dramatic, buttttt these sourdough dont want to be dramatic, buttttt these sourdough apple carrot muffins are the best thing I bake every fall! 🍎🥕they’re perfectly spiced, soft, sweet and moist,  and I love to top them with a little icing. If you’re looking for a fall sweet that isn’t toooo sweet and is still healthy,  the full recipe is available on my website  https://cultured.guru and linked right in my bio. happy baking!
nuance is needed in the alcohol conversation. Pe nuance is needed in the alcohol conversation. 

People in Blue Zones , particularly in Mediterranean regions, often drink 1-2 glasses of wine daily with meals and among friends, enjoying organic wines rich in antioxidants. 

This contrasts with new studies that show “no safe level of alcohol.” These new studies lump together all types of alcohol (including hard liquor) consumed in unhealthy ways, without distinction of specific lifestyle and beverage consumption environment.

I think context is key. Wine is not necessarily a reason for longevity in Blue Zones, but it is a small, supportive component of a larger lifestyle that includes a fiber-rich diet, regular physical activity, strong social connections, and a sense of purpose. Consumption is limited to about 1-2 glasses per day and is almost always enjoyed with food and in the company of friends and family. 

This turns wine into a ritual that promotes social bonds. Not a toxic coping mechanism.

And type of alcohol does matter. Many Blue Zone populations, especially in the Mediterranean, drink natural, organic, or locally grown and brewed wines, which have a much higher antioxidant content and a lower sugar, pesticide, and additive content. 

Because of all of this, I think more nuance is needed in the alcohol conversation.

(Disclaimer: I am very well aware of the epidemiology that states no amount of alcohol is safe. In the general population, especially in America, drinking patterns, social patters, and lifestyle are all predominately unhealthy. So yes, for the general, average population no amount of alcohol can be considered safe.)
