About Kambu
Kambu is a Hamburg-based manufacturer of fermented, non-alcoholic organic beverages based on traditional kombucha production. All varieties are created according to the company's own Ferm² formula, a double fermentation that develops natural acidity, fine carbonation and complex aromas. The beverages are produced unpasteurized and without artificial additives, 100% plant-based and with a reduced sugar content. Genuine ingredients such as ginger, lemon, hibiscus, beetroot, elderberry and mint are used. Kambu targets gastronomy, bars and the food retail trade as well as end consumers: the beverage serves as a non-alcoholic aperitif, as a mixer for cocktails and mocktails, and as a culinary ingredient for dressings, reductions or pickles. The sole proprietorship is run by founder Christian Frank and produces and distributes in Hamburg.
