Our Heritage Selection pays homage to the tradition of blending whiskeys by marrying our estate produced American Pot Still Whiskey with Grain Whiskey distilled in Ireland; aged a minimum of 18 months. The pot still whiskey is produced using an unmalted and malted barley mash, triple distilled in copper pot stills, and aged in charred American white oak casks. The grain whiskey was hand selected and brought home to Colorado to be finished in second-fill Colorado whiskey barrels. These two whiskeys are blended together to create a distinctly Irish-American expression.
