Distiller's Description The 'house' style of Jim Beam is characterised by a significant proportion of rye in the mash bill, along with a high percentage of corn, the remainder of the mash bill being made up of malted barley. There are vanilla and delicate floral notes on the nose of this four-year-old Bourbon. Initially sweet, with restrained vanilla, then drier, oaky notes develop, fading into furniture polish and soft malt in the finish
