The Bardstown Bourbon Co., Bardstown, Ky., is rolling out a new expression with Louisville-based distillery Copper & Kings American Brandy Co. The latest addition to Bardstown’s Collaborative Series, this product is a nine-year-old Tennessee bourbon finished for 18 months in Destillaré Orange Curaçao barrels. The new bourbon is available in limited quantities across all 13 markets.

“A brilliant orange nose takes the lead over a rich blend of baking spice, vanilla and maple,” said Herb Heneman, Bardstown Bourbon Co. vice president of sales and marketing, in a statement. “The bright citrus awakens the palate and leads to a magnificent, long lasting finish with just a touch of sweetness. You see a lot of ‘top shelf’ Margaritas or martinis, but never has there been a better base for a ‘top shelf’ old fashioned than this incredible release.”

Bardstown Bourbon Co.’s Destillaré Orange Curaçao finish expands the distillery’s Collaborative Series, a line of imaginative bourbons that have been finished in an array of wine, beer and spirits barrels. It is the sixth collaboration with fellow Kentucky distillery Copper & Kings. Prior collaborations with Copper & Kings include bourbons finished in American brandy, Muscat Mistelle, Oloroso Sherry and Apple brandy barrels, the latter of which was awarded a Double Gold at the San Francisco World Spirits Competition, the company says.

“There’s a lot of satisfaction in developing and shaping whiskey into surprising and adventurous profiles,” said Copper & Kings founder and Chief Executive Officer Joe Heron. “The collaboration with kindred spirits is what truly polishes the liquid. The infusion of friendship is what brings the magic.”

The Bardstown Bourbon Co. and Copper & Kings’ Destillaré Orange Curaçao is a 50 percent alcohol by volume expression that is packaged in a 750-ml bottle for a suggested retail price of $124.99.
