Parker’s Heritage Bourbon Finished In Orange Curaçao Barrels is the 12th edition of the annual Parker’s Heritage Collection. The bourbon was aged seven to eight years in the upper floors of Rickhouse Q, then finished for four months in barrels that previously held French Orange Curaçao liqueur. This is the second barrel-finished bourbon in the collection, following in the steps of the 5th Edition Cognac finished Kentucky Straight Bourbon Whiskey.
