The Woodford Reserve Master's Collection Select American Oak is the 14th release in the series. Woodford Reserve Distillery’s Master Collection™ honors the pioneering work of Pepper and Crow, applying their handcrafted methods to a variety of grain recipes, fermentation styles and maturation processes to create a range of unique whiskeys. To create oat grain, they used barrels specially made from select, Ozark-harvested trees to isolate the terroir of the wood and emphasize these flavors giving the whiskey a softer and nuttier flavor.
