In this episode, guests including an expert on kombucha, a researcher studying its health benefits, and a tea expert passionate about kombucha discuss the process of making kombucha, its flavors, and the health claims associated with it. They also explore the slow growth of kombucha in the UK, the rise in popularity in Australia, and the market opportunity it presents. Additionally, they talk about brewing kombucha at home during the pandemic, the transition to starting a tea farm, and the unique approach to brewing kombucha using British tea and homegrown fruit.
Resistance and prejudice towards high-quality non-alcoholic drinks in certain retail sectors may hinder the adoption of kombucha in the UK.
While kombucha contains beneficial microorganisms and potential health-promoting compounds, it has not been classified as a probiotic yet.

Understanding Kombucha: What it is and How it's Made
Kombucha is a fermented tea made by steeping a blend of black and green tea in hot water and sweetening it with sugar. A kombucha culture, known as a scoby, is then added, which consists of bacteria and yeast that ferment the tea and sugar into the final product. The fermentation process takes about a week or two, and the resulting drink contains various acids, such as acetic acid and gluconic acid, which are believed to have health benefits. Kombucha can also be brewed with different flavors and nutrients from other plants, allowing for experimentation and regional variations.
The Slow Growth of Kombucha in the UK
Despite being a popular drink in countries like the US and Australia, kombucha has not seen the same level of adoption in the UK. One possible reason for this slower growth is the resistance and prejudice towards high-quality non-alcoholic drinks within certain retail sectors. Traditional buyers in the alcohol industry may prefer the mystique and world of alcoholic beverages, leading to a reluctance to embrace and promote non-alcoholic alternatives. Additionally, the UK market for kombucha has not expanded as quickly as expected, with a limited variety of flavors and brands available. The potential and demand for healthier drink options, given the increasing number of people who want to reduce or eliminate alcohol consumption, make the slow growth of kombucha in the UK somewhat perplexing.
The Health Potential and Research on Kombucha
Kombucha is often associated with various health benefits, and while claims are made by enthusiasts and influencers, scientific research is still ongoing. The microorganisms found in kombucha, including acetic acid bacteria and different yeast strains, may contribute to its reported health effects. The drink also contains phenolic compounds, which can have antioxidant and potentially anti-hypertensive properties. Some studies suggest that kombucha may help reduce blood glucose levels. However, it's important to note that while kombucha contains beneficial microorganisms and potential health-promoting compounds, it has not been classified as a probiotic yet, as research is still needed to establish specific health benefits and identify optimal strains for different outcomes.
Kombucha has been around for a while but it has not had huge success in this country like it has in the US and Australia.
In this programme, Jaega Wise looks at why that may be as well as sampling some drinks from our BBC Food & Farming Awards finalists and investigating the health claims of kombucha.
This programme features Old Tree Brewery, William Kendall, Mark Ilan Abrahams, Paul Cotter, Lucy George from Peterson Tea and Kara Monssen.
