The process involves fermenting sugar water with kefir grains, a symbiotic culture of bacteria and yeasts. These grains, although called “grains,” are not related to wheat or other cereal grains. They consist of a polysaccharide matrix created by the microorganisms, forming a gelatinous structure that facilitates the fermentation of sweetened water. The fermentation process transforms the sugar water into a lightly carbonated, probiotic-rich beverage.
This beverage offers potential health benefits due to its probiotic content, supporting gut health and potentially improving digestion. Historically, similar fermented drinks have been consumed for centuries in various cultures for their perceived health properties. The simple ingredients and relative ease of production contribute to its appeal as a homemade probiotic source.
