Distilled from 100% rye and bottled in bond, the Rabble Rouser differs from its cousin, Roundstone Rye, in that it is distilled at a lower proof, allowing lots of earthy goodness from the grain to come through in the spirit. The whisky is aged for four years, making it among the oldest craft whiskey in the United States presently, and twice the legal age requirement for "straight rye whiskey."
