The Cooper Spirits Co. has launched Hochstadter’s Vatted Straight Rye Whiskey, the first to officially designate its blend of straight rye whiskies as vatted. The five straight rye whiskies (from U.S. and Canada), from four to 15 years old, were combined in vats, allowing the flavors to harmonize before being non-chill filtered and bottled. 100 proof.
