Calistoga Water Company, more commonly referre to as simply Calistoga is a producer of bottled water and mineral water in the Napa Valley of Northern California. The company was founded by Giuseppe Musante, a soda fountain and candy store owner in Calistoga, California. In 1920 he was drilling for a cold water well at the Railway Exchange when he tapped into a hot water source. In 1924 he set up a bottling line and began selling Calistoga Sparkling Mineral Water. The company became a major player in the bottled water business after Elwood Springer bought the small bottling plant in 1970
