The rising popularity of kombucha as a ‘healthy’ product has resulted in an increased incidence of home-brewing of the beverage, often using a SCOBY obtained from another household as a starter. Moreover, there have even been reports of toxicity associated with over-consumption of kombucha, particularly in immunocompromised individuals. However, most of these claims are unsubstantiated and lack scientific evidence, with few clinical trials carried out to date. The rise in popularity of kombucha is in part attributed to its purported health benefits, having been cited as having such abilities as boosting the immune system, alleviating IBS symptoms, aiding in weight loss and reducing blood pressure, to name but a few. The global kombucha market has seen significant growth in recent years, standing at USD 1.84 billion in 2019, with a projected growth rate of 23.2% by 2027. Black or green tea and sucrose are the traditional substrates for kombucha fermentation however, in recent years there has been a shift towards the use of alternative carbon and nitrogen sources, with the aim of increasing the functionality of the final beverage. Other metabolites formed as a result of kombucha fermentation include lactic, citric, malic and glucuronic acids vitamins minerals and phenolic compounds. During fermentation, yeasts hydrolyse sucrose to glucose and fructose as a by-product of ethanol fermentation, while AAB then convert ethanol and glucose into acetic acid and gluconic acid, respectively. Traditionally, culture-based methods were relied upon for characterisation of the microbial composition of kombucha, however the emergence of culture-independent techniques such as metabarcoding has allowed for a more in-depth analysis of kombucha microflora and their metabolic activities and interactions. are the core drivers of kombucha fermentation, although lactic acid bacteria (LAB) such as Lactobacillus and Leuconostoc have also been systematically isolated from the beverage. Acetic acid bacteria (AAB) of the genera Komagataeibacter, Acetobacter and Gluconobacter and yeasts such as Zygosaccharomyces spp., Saccharomyces spp. Kombucha is produced by fermenting sweetened tea using a symbiotic culture of bacteria and yeast (SCOBY), also known as a pellicle. The aim of this review is to provide an update regarding the current knowledge of kombucha production, microbiology, safety and marketing. Accordingly, the incidence of kombucha home-brewing has increased, meaning there is a requirement for individuals to recognise the potential hazards associated with fermentation and the relevant preventative measures to be undertaken to ensure the safe preparation of kombucha. The global kombucha market is rapidly increasing, with the rising popularity of the tea attributed in part to its purported health benefits, despite the lack of research in human subjects to substantiate such claims. In recent times, advancements have been made towards the optimisation of the fermentation process, including the use of alternative substrates, defined starter cultures and the modification of fermentation parameters, with the aim of producing an innovative beverage that is improved in terms of its physiochemical, sensory and bioactive properties. The microbial community of kombucha is a complex one, whose dynamics are still not fully understood however, the emergence of culture-independent techniques has allowed a more comprehensive insight into kombucha microbiota. They're always refrigerated, have visible culture strands, and offer.Kombucha is a carbonated, slightly acidic beverage traditionally produced by the fermentation of sweetened tea by a symbiotic culture of bacteria and yeast (SCOBY). But don't just take our word for it you can see the authenticity in every one of our bottles. When heated (pasteurized), filtered, or made from concentrate, Kombucha's innate nutritional goodness is compromised and weakened. ![]() If kombucha is not raw, then it's not the real deal. Appreciate what you have, accept your life the way it is and work on goals that make you feel happy - Divya Vidyasankar Thoppai (Former Payroll Specialist & Human Resources Chino, CA). ![]() Words of Enlightenment: Always be thankful for what you have in your life. I promise to always craft with pure love and true intentions, to nourish your body and nurture your health - GT Dave, Founder. To this day, every small batch is traditionally cultivated in 5-gallon glass vessels for 30 days - the longest ferment of any brand - using heirloom living cultures to naturally develop the most nutrients possible. That is the standard I set when I bottled my first batch of Kombucha in 1995.
