Perhaps most famous for its unique and striking bottle, which is shaped like the stills used to produce spirit, Willett Pot Still's also worth trying for the liquid inside.  The nose has aromas of chocolate malt, a bit of dried wood and tobacco, and is a good deal mustier than the average bourbon.  The flavor profile is classic bourbon, though:  vanilla, caramel, wood tannins, and a bit of bite.  That musty, pipe tobacco in an old library sensation remains as well.  I don't get as much spiciness from this bourbon, so however much rye there is in it doesn't express itself strongly.  The finish is pleasantly long and ends with a bit of spearmint tingle.  At $50 a bottle, it's not the best value in bourbon, but the bottle alone would make it fun to bring out and drink with company.
