Hillrock Double Cask Rye is a unique American Whiskey, handcrafted in small batches from rye grain, which has been naturally grown, milled, small batch pot distilled, aged and bottled by hand all on our Hudson Valley Estate. After aging in new #3 char American oak casks, the award winning Field-to-Glass whiskey is then aged in #4 char new American oak casks which add layers of caramel and vanilla to complement traditional rye spice.
