Master's Keep Cornerstone Rye is the fourth release in the Master's Keep series, and the oldest rye whiskey ever released by Wild Turkey. For this one-of-a-kind Limited Edition, Eddie Russell hand-picked and set aside a secret lot of his oldest and boldest rye whiskey barrels, all aged from 9 to 11 years, then used his nearly four decades of experience to create a perfectly balanced spirit. Aromas of vanilla, black pepper and toasted rye give way to cascading flavors of honey and baked apple before a long and lingering finish of spice and oak.
