Independent Irish whiskey distiller Cooley Distillery has launched a 15-year-old small-batch bottling of its Greenore Single Grain Whiskey brand.

The company claimed this to be the oldest bottling of an Irish grain whiskey ever released. The whiskey is aged in single-use Bourbon oak casks and the whiskey matures in the 200-year-old granite warehouses of the Old Kilbeggan Distillery in County Westmeath.

The introduction of the 15-year-old follows the launch of the Greenore 8-year-old. Production of the 15-year-old will be limited to just 5,000 bottles but the Greenore 8-year-old will be maintained as a permanent offering, Cooley said.
