Jack Daniels Whiskey is a Tennessee Whiskey that is filtered using Sugar Maple Charcoal to give it that hint of dry spice, nuts and a slight hint of smoke, smooth on the palate with notes of nutty caramel with a sweet oak finish.
The mix for Jack Daniel's Whiskey is, made from rye corn, malted barley; it is distilled, in copper stills. It is then purified, through 10-foot heaps of sugar maple and charcoal. The organisation refers to this filtering process as "mellowing". This additional step, known as the Lincoln County Method, removes contaminants with the flavour of corn. The corporation stresses that this extra step makes the product different from a bourbon whisky. However, Tennessee whisky is required to be "a straight Bourbon Whiskey" under terms of the North American Free Trade Agreement and Canadian law. After the filtering, the alcohol it is stored in newly handcrafted oak barrels, which give the whisky its colour and most of its flavour. A distinctive aspect of the screening method is that the Jack Daniel's brand crushes its charcoal, previously to the process.
The merchandise label mentions that it is a "sour mash" whisky, which means that when the pulp is, made some of the wet solids from an earlier used batch are blended in to contribute to making the fermentation method operate more consistently. This is, standard practice in American whiskey creation.
