Calpico, also known as Calpis, is a Japanese non-carbonated beverage made from high quality non-fat milk through lactic acid fermentation. It is similar to yakult, kefir, or kumis in flavor but significantly lighter and more refreshing. Calpis is sweet and tangy with a hint of citrus and yogurt. Calpico original beverage cans contain the flavor of original Calpis in both non-carbonated and soda forms.
