So how do we honour Jack Daniel's 160th? The same way we honour him any other day. All Jack ever asked was that we all make each day the best we can. He was of course talking Whiskey. Seven generations later, Jack Daniel's still mellow their Whiskey just as Mr. Jack did, imparting a distinctive smoothness folks have come to expect. Charcoal mellowing makes Jack Daniel's what it is, a Tennessee Whiskey and not a Bourbon. It fully refines the Whiskey even before a spell of slow ageing in American oak barrels, and Mr. Jack wouldn't have it any other way.
