Master’s Keep Cornerstone is the fourth release in the limited edition 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 leveraged his nearly four decades of experience to create a perfectly balanced spirit that showed off just what an American rye whiskey could be. 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.
