Bottled at 114-proof, Bootleg V references Bob Dylan's "The Beaten Path" series, a fitting nod to the left-field obscurity of this bottle's cask finishing. Heaven's Door Bootleg V is the second-oldest release in this annual limited edition series, and arguably the most unique... it's not every day that you come across a Spanish Vermouth cask-finished bourbon, let alone one that's been aged 18 years.
