Calpis (カルピス) is a Japanese uncarbonated soft drink, manufactured by Calpis Co., Ltd. (カルピス株式会社) , headquartered in Shibuya, Tokyo. The beverage has a light, somewhat milky, and slightly acidic flavor, similar to plain or vanilla-flavored yogurt, or Yakult. Its ingredients include water, nonfat dry milk, and lactic acid, and is produced by lactic acid fermentation.
In English-speaking countries the beverage is sometimes called “Calpico,” because “Calpis” may sound like “Cow Piss”.
Japan belongs to the temperate zone with four distinct seasons, but its climate varies from cool temperate in the north to subtropical in the south. In winter, a high-pressure area develops over Siberia, and a low-pressure area develops over the northern Pacific Ocean. The result is a flow of cold air eastward across Japan that brings freezing temperatures and heavy snowfalls to the central mountain ranges facing the Sea of Japan, but clear skies to areas fronting on the Pacific.
