What Is Kefir? A Drink with Over 36 Strains of Beneficial Microbes
Kefir is a fermented drink born from the symbiosis of sugar and nutrients with a complex microbial ecosystem known as tibicos grains. These grains are a living, self-sustaining community of bacteria and yeasts that have been passed down through generations. At Rokabo, we cultivate heirloom tibicos grains in a controlled laboratory environment to preserve their biodiversity and potency.
Unlike ordinary yogurts that contain only a few strains of lactic acid bacteria, kefir harbors a diverse array of microorganisms—Lactobacillus, Bifidobacterium, Streptococcus, Saccharomyces, and the unique Lactobacillus kefiranofaciens. This diversity enables a double fermentation process that reduces sugar while enriching the live microbial count.
Each 280 ml bottle of Rokabo kefir has a pH of 4.32—a level that supports the survival of these microbes in the gut while delivering a pleasantly tangy, mild flavor that fits effortlessly into urban lifestyles.
Microbial Diversity in Kefir
Rokabo kefir contains 36 distinct strains of live microorganisms—far more than conventional probiotic products. This richness allows the microbes to adapt and colonize the gut more effectively, even in individuals with a varied microbiome.
Key strains include Lactobacillus kefiranofaciens, which contributes to the formation of kefiran—a polysaccharide that supports intestinal barrier function. Bifidobacterium longum aids digestion and reduces bloating, particularly in those with lactose intolerance. Streptococcus thermophilus further supports digestive comfort.
With a concentration of ~12 billion CFU per milliliter, every sip delivers a high density of viable microbes. This consistent potency across every 280 ml bottle increases the likelihood that these beneficial organisms will reach and influence the gut microbiome.
A Meticulous Fermentation Process
Every bottle of Rokabo undergoes a 24-hour double fermentation. In this process, the sugars in the fruit juice or base solution are consumed by the microbes and transformed into lactic acid, carbon dioxide, and beneficial metabolites. The result is a drink with only 2.1 grams of sugar per bottle—naturally low, with a balanced sweetness.
The double fermentation also ensures that the pH stabilizes at 4.32, a safe and gentle level for daily consumption. No preservatives or artificial additives are used. Each batch is rigorously tested for safety, purity, and microbial consistency.
Flavor and Ritual of Drinking
Rokabo kefir is available in five flavors: Original, Sakura, Yuzu, Matcha, and Thai Herb. Each is designed to resonate with Asian palate preferences—bright, aromatic, and refreshing.
Drinking kefir in the morning or after a meal can gently support digestion and immunity. With its high diversity and concentration of live microbes, Rokabo kefir may contribute to long-term gut microbiome balance.
For those seeking a drink that embodies the quiet science of fermentation—blending Japanese simplicity with Thai warmth—Rokabo kefir offers a living culture.
