What Is Kefir? A Live Culture in a 280 ml Bottle
Kefir is a fermented drink born from the symbiotic work of diverse microorganisms—lactic acid bacteria, yeasts, and acetic acid bacteria—all living within heritage tibicos grains. The double fermentation process, spanning 24 hours, allows each of the 36 strains to reach its full potential without additives or extraction methods that disrupt natural integrity.
A 280 ml bottle of kefir holds a vibrant community of live microbes. Its pH of 4.32 creates an environment that favours probiotic survival in the gut. The residual sugar sits at just 2.1 g per bottle—lower than typical drinks—a result of the prolonged fermentation that allows microbes to consume sugar efficiently.
The CFU concentration of Rokabo kefir is ~12 billion CFU/ml, a value continuously verified to ensure high levels of live microbes in every bottle. While not calculated as a per-bottle total, this concentration supports effective delivery of microbes to the large intestine, helping maintain a balanced microbiota.
36 Probiotic Strains: The Heart of the Gut Ecosystem
Rokabo’s kefir contains 36 live probiotic strains, covering key genera such as Lactobacillus, Bifidobacterium, Streptococcus, and Saccharomyces, alongside the unique Kefiranofaciens—a strain that produces kefiran, a biopolymer that may help reinforce the intestinal barrier.
This diversity does more than support digestion; it influences the immune system, with up to 70% of immune cells residing near the gut. These microbes may aid nutrient absorption, digestion, and the modulation of low-grade inflammation in the gut.
The double fermentation method allows each strain to thrive in its optimal environment at different times, creating a microbial balance close to nature. It is not merely about increasing probiotic quantity; it is about cultivating a sustainable ecosystem within the bottle.
Nutritional Value Beyond Taste
Rokabo kefir is not only rich in probiotics but also in bioactive compounds naturally generated during the 24-hour double fermentation: lactic acid, B vitamins, digestive enzymes, and antioxidant peptides. These arise spontaneously from the microbial activity.
The residual sugar of just 2.1 g per bottle reflects the efficiency of fermentation—microbes have used sugar as fuel almost completely, resulting in a low glycemic index drink suitable for those managing blood sugar or seeking a less sweet fermented beverage.
The pH of 4.32 keeps the microbes alive in a favourable environment while remaining safe for daily consumption. Despite its acidity, the acids are natural and well-balanced by the body.
A Sustainable Kefir Culture
Drinking kefir daily is not just about adding probiotics; it is about cultivating a living practice of gut care. Rokabo produces kefir with respect for nature, using heritage tibicos grains and precise fermentation control.
The flavour range includes Original, Sakura, Yuzu, Matcha, and Thai Herb—blending Thai cultural notes with Japanese simplicity. Each bottle is presented in Neo-Wabi Bio-Lab glass, reflecting natural beauty and fermentation’s subtlety.
