Breckenridge Bourbon Whiskey takes in-house distillate made from a mash bill of 54% yellow corn, 38% green rye, and 8% barley and blends it with fine Rocky Mountain water and the painstakingly slow process of aging in new charred American white oak barrels. While we can't bottle the fresh mountain air and sunshine, we can give you the rich aroma and smooth taste of Breckenridge® Bourbon Whiskey. We think we've done that, and then some.
