What Is Kefir? A Complex Biological Structure
Kefir is a probiotic drink born from the fermentation of milk with Tibicos grains — not seeds, but a living community of microorganisms living in symbiosis. Within Tibicos grains reside lactic acid bacteria, beneficial yeasts, and select fungi that work together in balance. This structure gives kefir a biological diversity far greater than typical fermented drinks.
The fermentation of kefir proceeds in two cycles of 24 hours each, allowing the microorganisms ample time to grow and produce beneficial metabolites — lactic acid, acetic acid, and antioxidants. The finished product holds a pH of 4.32, an acidity that supports the survival of beneficial microbes while preserving a mild, balanced flavor.
Each bottle is 280 ml, a standard volume designed for convenient single servings without compromising microbial concentration. Every bottle contains approximately 12 billion CFU/ml of probiotics, a value continuously verified in our laboratory.
Microbial Diversity: Kefir Surpasses Yogurt
Kefir hosts up to 36 strains of microorganisms, including both bacteria and yeasts of benefit: Lactobacillus, Bifidobacterium, Streptococcus thermophilus, Saccharomyces cerevisiae, and Kefiranofaciens — a strain unique to Tibicos grains. This diversity allows kefir to modulate the gut microbiome across multiple dimensions.
Yogurt typically contains only 2 to 5 strains, such as Lactobacillus acidophilus and Bifidobacterium lactis, which are cultured and added. Kefir therefore holds greater potential to reshape the intestinal ecosystem — not merely by adding microbes, but by supporting the growth of native flora.
The coexistence of bacteria and yeasts enables a double fermentation that breaks down nutrients more effectively and reduces residual sugar. Each bottle contains just 2.1 grams of sugar — far lower than most fermented drinks.
Impact on Gut Health: More Than Just Adding Bacteria
Regular consumption of kefir may help restore balance to the gut microbiota, particularly in those with irritable bowel syndrome, bloating, or chronic constipation. The microbes in kefir play a role in breaking down lactose, allowing some lactose-intolerant individuals to consume it without discomfort.
Furthermore, the metabolites produced during fermentation exhibit local anti-inflammatory and immune-stimulating properties, which may help reduce the risk of chronic diseases linked to gut inflammation. However, these effects remain within the scope of scientific investigation — kefir is not claimed to cure any condition.
Consistent intake of kefir may improve digestive function, reduce bloating, and enhance gut comfort, though results vary by individual.
The Culture of Drinking Kefir: Continuity of Nature
Kefir is more than a beverage — it is part of a fermentation culture passed down for centuries, especially in the Caucasus, the birthplace of Tibicos grains. At Rokabo, we carry forward this tradition by blending Japanese simplicity with Thai warmth, producing in our Neo-Wabi Bio-Lab in Nonthaburi.
Every bottle of kefir is the result of precisely controlled fermentation, with no preservatives, no pasteurization, and no additives. The taste reflects the natural character of the microorganisms living in the Tibicos grains.
Our kefir is available in several flavors: Original, Sakura, Yuzu, Matcha, and Thai Herb. Price per bottle is ฿320–฿380. Subscribers receive a 15% discount and weekly delivery, making kefir a sustainable part of daily life.
