Jack Daniel's – Tennessee Whiskey (20cl, 40%)

Jack Daniel's is a Tennessee whiskey rather than a bourbon, in a 20cl pocket flask at 40%. It follows the basic rules for bourbon, with one extra step: after distillation the spirit is filtered through a layer of charcoal three metres thick, which gives its well-known softness. It is typically described as a lightly fruity mix of caramel, vanilla, spice and toasted oak.
