Description: Kombucha fermentation is a biological process that transforms sweetened tea into a fizzy and slightly acidic beverage, thanks to the action of microorganisms such as yeasts and bacteria. This process begins with the preparation of a tea infusion, which is sweetened with sugar. Next, a symbiotic culture of bacteria and yeast known as SCOBY (Symbiotic Culture Of Bacteria and Yeast) is added. During fermentation, which can last from one to three weeks, the sugars are metabolized by the yeasts, producing carbon dioxide and alcohol, while the bacteria convert the alcohol into acetic acid, giving kombucha its characteristic sour taste. This process not only creates a refreshing drink but also generates beneficial compounds such as probiotics, which are known for their positive effects on digestive health. Kombucha has gained popularity in recent years as a healthy alternative to sugary beverages, and its homemade preparation has attracted followers worldwide, becoming a symbol of fermentation culture and interest in functional foods and drinks.
History: Kombucha has its origins in Asia, specifically in China, where it is believed to have been consumed for over 2,000 years. It is attributed the name ‘tea of immortality’ due to its supposed health benefits. Over the centuries, the drink spread to Japan and Russia, where it became even more popular. In the 20th century, kombucha reached the West, especially during the 1960s, when its potential as a health drink began to be valued. In recent years, its popularity has grown exponentially, becoming a global phenomenon.
Uses: Kombucha is primarily used as a refreshing and healthy beverage. It is attributed with probiotic properties that can benefit digestive health. Additionally, it has been used in traditional medicine in some cultures to improve overall health and boost energy. Its use in gastronomy has also been explored, as an ingredient in cocktails and dressings.
Examples: A practical example of kombucha use is its homemade preparation, where fermentation enthusiasts can experiment with different types of tea and flavors, such as ginger, fruits, or herbs. It is also found in health food stores and cafes, often in flavored varieties that appeal to a broader audience.
