Intensely amber, the fastidious mellowing process sets Jack Daniel's apart, refining the rich flavours before they are matured in charred white oak barrels. The tasters use their senses, just like Jack Daniel himself did. In fact, more than a century later, the Tennessee Whiskey is still judged the same way. By the way it looks. By the way it smells. And of course, by the way it tastes. 40% Alc./Vol.
