Water Kefir

Sweet, tart and delightfully effervescent, water kefir (also known as tibicos) is a naturally fermented drink that's rich in beneficial bacteria. Its delicate flavor and natural fizziness make it an excellent substitute for sodas and soft drinks. You can make it at home with a few easy steps.

What is water kefir?

Water kefir, or tibicos, is a traditional fermented drink made by culturing water, sugar, and fruit with a starter culture. The starter culture contains various beneficial bacteria and yeasts that produce a slightly tart, effervescent drink.

While its specific origin is unclear, researchers suspect that water kefir originated in pre-Columbian Mexico. It is still used in Mexico today in some preparations of tepache - which is a lightly fermented drink often made from corn or pineapple.

Water Kefir Grains (Tibicos)

Like kombucha and milk kefir, you need a SCOBY or symbiotic culture of bacteria and yeast to culture water kefir properly. The bacteria present in this culture produce small, gelatinous crystals called water kefir grains or tibicos.

And those little crystals turns sugar water into a bubbly, fermented drink. Most importantly, you can't brew the drink without them.

These tiny, crystal-like grains can form naturally beneath the skin of prickly pear cactus fruits (1). Further, it’s likely that early brewers captured tibicos from the wild and then cultivated the culture through domestic brewing.

Rich in Beneficial Bacteria

Like all cultured drinks, water kefir is naturally rich in beneficial bacteria and yeasts. And for people who are dairy-free and who cannot eat milk kefir or yogurt, it's an excellent source of probiotics

Researchers have studied the microbial composition of water kefir since the late 19th century(2). And water kefir cultures typically contain nearly 60 strains of lactobacillus bacteria, yeasts and other microbes(3). That's more than yogurt, but less than milk kefir.

The exact bacteria and yeasts found in your tibicos grains vary from culture to culture. Each culture is dynamic, and the microbes native to your kitchen will influence the culture's full microbial makeup. Although some strains of bacteria and yeast are common to almost all water kefir grains, like lactobacillus hilgardii and saccharomyces cerevisiea.

Is it good for you?

Water kefir, like most fermented foods, supports gut health and systemic wellness. The beneficial bacteria in the water kefir grains consume the sugar in the sugar water, and as they metabolize the sugar, they produce a variety of beneficial acids, food enzymes, B vitamins and more beneficial bacteria.  This process of fermentation also reduces the sugar content of the drink slightly.

• Gut Health. Water kefir is particularly rich in probiotics.  In other words, it’s those beneficial bacteria that help to support gut health.
• Cellular Health. Some research shows that water kefir supports healthy cells and may have anti-carcinogenic properties (4).
• Oral Health. Fermented tonics may help to support oral health, too (5).

Of course, while water kefir can be beneficial for many people, it can also be a poor choice for others.  It still retains a fairly high amount of sugar, even though probiotics convert some of that sugar to beneficial acids. So for people who struggle with blood sugar regulation, fermented vegetables make a better choice.

Probiotic-rich foods and drinks can have a laxative effect, especially for newcomers. So, if you’re just starting out, try drinking only 4 ounces at a time - or about half a cup. And then pay attention to how you feel.

Water Kefir and Alcohol

Like all fermented beverages, water kefir contains a small amount of alcohol - around 0.5% to 0.75%. To clarify, that's about the same amount that you'd find in over-ripe fruit or in kombucha.

If you're concerned about alcohol content in the brew, you can test it with a hydrometer (like this one), often used by home brewers, or read this piece about alcohol content and water kefir.

Brewing Tips

Once you get the hang of brewing your water kefir, there's a few thing you can do to make sure you have a consistently good drink every time.

• Use filtered or dechlorinated water. Chlorine is strongly antibacterial. And so it can damage your tibicos grains over time.
• Use an unrefined cane sugar like jaggery, panela or rapadura. Water kefir thrives in a mineral-rich environment, and unrefined sugars are rich in minerals.
• Use a caloric sweetener. Your culture needs sugar in order to thrive. While unrefined sugar works best, you can also use white sugar, molasses, honey and coconut sugar. Avoid noncaloric sweeteners like stevia and xylitol.
• Add a liquid mineral supplement if you use white or refined sugar to give your culture the minerals it needs to grow.
• Add dried fruit like figs or raisins to your brew. Dried fruit gives your grains much-needed minerals and will float when the kefir is finished.
• If you want to take a break, store your grains in a jar in the fridge covered by sugar water. Change the water every two weeks.
• Stir thoroughly before bottling it to distribute the yeasts. Yeast activity is what gives you great bubbles. Evenly distributing the yeast among your bottles will give you better and more consistent results.

How to Make Water Kefir

To make water kefir, you'll need to mix sugar and water together, and then cool it to room temperature before adding your grains. Drop in some dried fruit for minerals, and allow it to culture at least 24 and up to 72 hours before straining and bottling.
