Eight hundred gallons of water feed Lynchburg’s greatest natural resource, Cave Spring Hollow, from deep beneath the Earth’s surface every minute, the stuff that instills the spark of life in Jack Daniel’s whiskey. The water is cool at 56 degrees. Jack Daniel bought the hollow and the adjoining land for USD 2,148, a fortune in those days. There were no sediments or impurities, only clean, pure spring water. It is nature at its pristine best. The minerals from the limestone cave imbue the water with minerals, contributing to the full-bodiedness of Jack Daniel’s. The limestone leaches out iron from the water, which is good for any whiskey. Jack Daniel’s around the world is made with water from the hollow. It deserves the best care.
