What is water kefir?

Coconut water kefir.
Water kefir is made by creating a culture for bacterial fermentation

It’s a drink fermented through microbial cultures of the same name, also known as SCOBY (Symbiotic Colony of Bacteria and Yeast). That’s to say that a colony of lactic and acetic bacteria, yeasts, and microorganisms work symbiotically on milk or water, depending on if you want to make milk kefir or water kefir, to get a fermented drink.

For the kefir to ferment the water, you need to dissolve some nutrients in it that will turn it into an optimal environment for the development of your microbial culture. We’ll talk more about that when we show you how to prepare this drink at home.

Kefir grains have a bland and gelatinous texture, similar to cauliflower. Milk kefir grains are whitish, while water kefir grains are transparent.

It’s important to know the difference in order to be able to use the correct culture to ferment the drink that you want. Let’s look at how to prepare this fermented drink:

  • 3 soup spoons of whole cane sugar
  • 1/2 of a lemon (optional)
  • 3 heaped tablespoons of water kefir grains


  • A large glass container, with a wide mouth and a plastic or glass lid (not metal)

  4. Next, let the mixture sit for two or three days at room temperature (between 15 and 30 degrees Celsius, or 59 to 86 degrees Fahrenheit). During the fermentation process, the kefir grains will eat the sugar and create organic acids, fermenting the water.
  5. Enjoy your drink and its benefits!
