The Cooper Spirits Co. today announced Lock Stock & Barrel 21-Year Straight Rye Whiskey, the fifth release in the Lock Stock & Barrel series.

This new product is the oldest yet from the brand.

Lock Stock & Barrel 21-year is double distilled in copper pots from a mash bill of 100 percent rye grain. A “robust cut” is selected by master distillers, then the unfiltered spirit is aged in new charred American Oak barrels in cold weather for 21 years and bottled at 111 proof, the company reports. The result are flavors that suggest warm spiced date cake, treacle toffee, orange peel and baking spices.

“With the rye whiskey category continuing to grow in popularity it is a unique distinction to be able to introduce this rare and high aged offering that expands upon the quality of the Lock Stock & Barrel series,” says Chad Solomon, Cooper Spirits director of innovation. “We pride ourselves on being a pioneer in this category and are committed to continued innovation that attracts new tasters to this premier spirits category.”

The spirit comes in an opaque black bottle, embossed with a black-on-black 21-year age statement in a minimalist design. The bottle comes in a wooden box that is charred in the Shou Sugi Ban process.Allocated to just 1,200 cases, Lock Stock & Barrel 21-Year is available at specialty retailers nationwide at a suggested retail price of $499.99 per 750-ml. bottle.
