The Woodford Reserve Master's Collection Select American Oak is the 14th release in the series. Woodford Reserve Distillery's Master Collection honours 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 flavours giving the whiskey a softer and nuttier flavour.
