Jack Daniel's have Charcoal Mellowed their whiskey drop by drop, then let it age in their own handcrafted barrels. & they don't follow a calendar. Their Tennessee Sippin' Whiskey is ready only when their tasters say it is. They use their senses, just like Jack Daniel himself did. In fact, more than a century later, Jack Daniels Tennessee Whiskey is still judged the same way. By the way it looks. By the way it smells. & of course, by the way it tastes. Appreciating it for what it is & not comparing it your favourite straight whiskey, a special edition winter drink from Jack Daniel's, originally made for the Jack-crazy German market.
