Masterson's is all rye and only rye, meeting the strictest definition of traditional rye whiskey. The rye is grown in the verdant Pacific Northwest, and we choose only rye that exhibits the perfect combination of weight, plumpness and rich, earthy fragrance. These key characteristics, along with our meticulous distillation process, give Masterson's its uniquely smooth taste. Masterson's is a 100% rye whiskey that far exceeds industry standards for rye whiskey. Our artisans incorporate only the most fragrant and plump grains of rye and pure glacial water from the northern Rockies into a meticulous distillation process that utilizes an old-fashioned pot still.
