Jeffersons Manhattan Barrel Finished Cocktail has a ripe aroma of Madeira wine and vanilla extract, which leads to a sharp palate filled with bitter herbs, vermouth and citrus. The finish is clean and lengthy, with soft notes of licorice, oak and root vegetables making the final statement. Developed by Jefferson founder Trey Zoeller in partnership with David Granger, Editor-in-Chief of Esquire USA. The pair spent two years and dozens of attempts honing in on the perfect recipe, which they ultimately found by mixing Jeffersons Bourbon, dry and sweet vermouth and barrel aged spiced cherry bitters. The exact bourbon used is six years old - and once mixed with the vermouth and bitters, the resulting liquid is aged for an additional 90 days in oak barrels before being bottled.
