Water Kefir Culture

Water kefir culture is a symbiotic colony of bacteria and yeasts, often referred to as 'kefir grains,' that ferment sugars in water. These cultures are typically grown in a sugar-water solution, producing a probiotic-rich beverage. The fermentation process creates a slightly effervescent and tangy drink.

Manufacturers use water kefir culture to create probiotic beverages, often marketed as a healthier alternative to soda or other sugary drinks. It is added to enhance the drink's flavor profile with a natural tang and effervescence. It is commonly found in bottled water, juices, and other ready-to-drink beverages.

Water kefir is generally recognized as safe (GRAS) by the FDA for use in food. The fermentation process produces probiotics, which are live microorganisms that may benefit gut health. JECFA has evaluated some probiotic cultures, but specific evaluations for water kefir culture may vary. Research into the health benefits of probiotics is ongoing, with some studies suggesting positive effects on digestion and immunity, while others show mixed results.
