MT recalls Mormon whiskey known as "valley tan."
Mark Twain, Roughing It (Hartford, Conn.: American Publishing Company, 1873), 109
It was the exclusively Mormon refresher, "valley tan." Valley tan (or, at least, one form of valley tan) is a kind of whisky, or first cousin to it; is of Mormon invention and manufactured only in Utah. Tradition says it is made of (imported) fire and brimstone. If I remember rightly no public drinking saloons were allowed in the kingdom of Brigham Young, and no private drinking permitted among the faithful, except they confined themselves to "valley tan."
