Why Kombucha Can Enrich Your Life

January 15th is World Kombucha Day (National Booch Day)! Our favorite day! Why has kombucha fascinated people for so long, and what distinguishes this fermented tea drink from classic soft drinks?

Back to an Original Diet

This fermented tea drink is not just a refreshing beverage, but a way of life. Life often moves at a fast pace, and the many stimuli can be overwhelming, or external circumstances can create pressure. To make kombucha, we must be patient and allow the fermentation to proceed slowly. The result is a living, delicious, and refreshing drink that naturally enriches our lives. Kombucha combines the long tradition of fermentation with the characteristic taste of tea, natural acids, and a vibrant production culture. Depending on the recipe, it results in a sweet-sour, sparkling drink with its own unique character. Patience pays off. Good things usually take time to develop and can then sustainably change your life. A drink produced through traditional food craftsmanship, entirely in the spirit of the Slow Food movement, which not only tastes good but is also nutritious and does not unnecessarily strain the Earth's resources and our environment.

Kombucha is Made from a Tea Base

Good and flavorful tea is essential for an intensely flavored kombucha. The SCOBY consists of various yeasts and bacteria, as well as small microorganisms, and requires nutrients like caffeine, nitrogen, and theanine to grow and thrive. These are found in Camellia Sinensis tea varieties. Tea provides the SCOBY with important antioxidants and polyphenols and serves as a nutrient medium. It also contains many important nutrients, such as vitamin C and B. After up to 14 days of fermentation, the initial sweetened tea transforms into a refreshing drink with a comparatively low sugar content. The sugar is almost completely metabolized by the SCOBY, allowing other important nutrients to form. These include, for example, organic acids and vitamins, as well as gluconic acid, which is responsible for the kombucha flavor.

Save on Supplements Through Conscious Nutrition

Often, we are not conscious enough of what we consume, leading to deficiencies that many of us try to compensate for with supplements. If you look at your diet more closely, sometimes only small adjustments can help prevent these nutrient or vitamin deficiencies. A varied diet can contribute to the supply of many nutrients. However, whether a specific nutrient deficiency exists and whether supplementation is useful must be assessed individually. Kombucha should not be understood as a substitute for targeted supplementation in the case of a proven deficiency.

These ingredients can be formed during kombucha fermentation:

Amino acids Amino acids are the smallest building blocks of proteins and play an important role in the human body. Among other things, they are needed for the formation of the body's own proteins and are involved in numerous metabolic processes. Some amino acids, or compounds formed from them, also play a role in signal transmission between nerve cells.
Butyric acid Butyric acid is one of the short-chain fatty acids and can be formed during the microbial breakdown of certain carbohydrates. In the human large intestine, butyrate is also formed by certain gut bacteria. There, it serves as an energy source for cells of the intestinal lining, among other things, and is the subject of intensive research on the gut and microbiome. Whether and in what quantity butyric acid is present in a specific kombucha depends on the culture and fermentation conditions.
Succinic acid

Succinic acid, also called succinate, occurs naturally in human metabolism and is an intermediate product of various biochemical processes. It can also be formed during fermentation processes. Whether and in what quantity succinic acid is contained in a specific kombucha depends on the culture used and the fermentation conditions.

B Vitamins The group of B vitamins includes various vitamins that fulfill different functions in the human body. In scientifically studied kombucha samples, the following B vitamins, among others, have been described: vitamin B1, vitamin B2, vitamin B3, vitamin B5, and vitamin B12. However, which of these are actually present in a specific kombucha and in what quantity must be determined for each product.
Acetic acid The acetic acid produced during kombucha fermentation contributes significantly to the characteristic sour taste and low pH value. The acidic environment can make it difficult for many undesirable microorganisms to grow, but it does not replace hygienic production and offers no absolute protection against contamination.
Enzymes

Enzymes are predominantly proteins, which are composed of amino acids and act as catalysts for chemical reactions. In the human body, they play an important role in digestive and metabolic processes, among others. Various enzymes are also involved in fermentation processes. Which enzymes are present in a specific kombucha and in what quantity depends on the culture and production.

Gluconic acid Gluconic acid can be formed during the oxidation of glucose by certain microorganisms. Bacteria of the genus Gluconobacter can be involved in this process and also occur in certain kombucha cultures. The concentration of gluconic acid achieved in the finished drink depends on the respective fermentation conditions.
Lactic acid bacteria Lactic acid bacteria are a group of microorganisms that can occur in various fermentation processes. Lactic acid bacteria have also been detected in certain kombucha cultures. However, whether such microorganisms can be classified as probiotics depends on the specific, scientifically studied strain, its quantity, and other prerequisites. Therefore, the mere presence of live lactic acid bacteria does not allow for a general statement about an effect on the gut flora or immune system.
