For me, Tennessee whiskey looks like bourbon’s wild neighbour. Its smell and taste differs from bourbon whiskey so much, its character’s so robust.
I think the point is the Lincoln County Process according to which the whiskey is filtered through a huge layer of sugar maple charcoal. Definitely that makes a difference in the Jack Daniel’s aroma.
One day I got a chance to taste interesting Jack Daniel’s product – Jack Daniel’s Single Barrel Tennessee Whiskey. That’s nice idea: every barrel brings whiskey with unique flavor. So you can’t say that you tasted Jack Daniel’s Single Barrel because you tasted whiskey just from one barrel.
