Diesel Whiskey Row, made by AJ Fernandez in Nicaragua, is the latest brand that uses barrel aging to enhance the cigar’s profile. The Diesel Whiskey Row’s Mexican San Andrés binder leaves are aged in wooden barrels that previously contained Rabbit Hole bourbon. The Diesel Whiskey Row’s filler uses Nicaraguan tobacco that has been aged five to eight years. The cigar’s Ecuadorian habano wrapper has undergone a five-year aging process too. Contrary to what one might expect, barrel aging does not give the cigar an overpowering bourbon flavor. In fact, the Diesel Whiskey Row is a medium-strength cigar with strong notes of oak and leather. If you have ever wanted to experience a bourbon barrel-aged cigar, the Diesel Whiskey Row is great place to start.
