Tincup American Whiskey is the brainchild of Colorado-based Jess Graber. A distiller as a hobby for 30 years, he turned full-time in 2004. A high rye whiskey, made with a bourbon-style profile but more powerful and spicier, the cap also works as a cup.Tin Cup American Whiskey is the newest expression produced by Jess Graber. The whiskey is crafted from a mash of 64% corn, 32% rye and 4% malted barley. After distillation through copper-pot stills, the whiskey is matured in new, charred white oak barrels for four to five years. Then, the whiskey is shipped to Colorado, where it is brought to proof with Rocky Mountain snowmelt.
