For this purely Pennsylvania collaboration, Dad’s Hat takes barrels used to age their whiskey and sends them to Grinarml’s Maple Syrup Company in Somerset. Grinarml’s syrup ages in those barrels for several months. Then, Dad’s Hat’s barrel-aged whiskey is put back into those barrels to age some more. The whiskey picks up just a hint of maple flavor to create an end product that’s not too heavy or too sweet. It’s a special kind of give and take that makes this whiskey and maple syrup the best of friends.
