Woodford Reserve's Kentucky straight malt whiskey is made from a mashbill of 51% malted barley, 47% corn, and 2% rye. It is a type of American malt whiskey, which is closer to bourbon and American rye than to scotch single malts. A straight malt whiskey must have at least 51% malted barley and should not be confused with a single malt whisky, which must have 100% malted barley. Woodford Reserve is a brand of premium small batch Kentucky straight bourbon whiskey produced in Woodford County, Kentucky.
