Koso

Koso is a Japanese beverage made by fermenting various plant-based ingredients, primarily vegetables and fruits. The drink is packed with nutrients, good bacteria, probiotics, and prebiotics. It is mostly promoted as a healthy, nutritionally beneficial beverage that boosts metabolism and immunity.

Koso is traditionally made with different fruits, leafy green and root vegetables, mushrooms, seaweed, and herbs. The ingredients are fermented with sugar, yeast, and sometimes koji mold and lactic acid bacteria, usually for several months or years.

The final profile and color can significantly vary depending on the ingredients, but it usually has a pleasant taste, and it should always be additive-free. This fermented beverage has a centuries-old tradition. It was primarily used as a supplement that provided essential nutrients among people with poor and imbalanced diet, but now it is heavily promoted as an excellent drink that improves general well-being and is especially beneficial for skin health and weight loss.
