Jack Daniel\'s Single Barrel Tennessee Whiskey, the world\'s first charcoal mellowed whiskey to be bottled by the barrel was first introduced in February 1997. It allows whiskey aficionados to sample the work of individual barrels, comparing the subtle difference imbued by the new American white oak barrels and the intense maturation process. Each barrel of whiskey is sampled as it comes of age by their current master distiller (and his tasting panel), they then set a few aside. These barrels are the ones with the smoothest taste and the most intense flavour of varying degrees of toasted oak, caramel and vanilla. The few destined for something special - to be sold, one barrel at a time to our most discriminating customers. Jack Daniel\'s Single Barrel is always found in the upper most parts of the barrelhouse - they like to call this the \'Penthouse\'. Because every barrel is different and in various locations in the barrelhouses no two barrels are the same. Each decanter style bottle of Jack Daniel\'s Single Barrel proudly carries details of the rick number, barrel number and bottling date, communicating that each bottle is completely unique.
