Our Four Grain Bourbon story starts with two Colorado family farms where heritage corn and heirloom varietals of wheat, barley and rye are grown. Those grains find their expression during our labor-intensive cooking technique, bringing each grain’s individual character to life, while open-air sour mash adds soulful complexity. After three years in 53-gallon charred oak barrels, influenced by our high-altitude climate, an entirely novel bourbon unfolds.
