This is a cask strength 13-year-old Kentucky bourbon, finished in Vino de Naranja Casks. Native to Southern Spain, these casks are used to age an exclusive type of white wine utilizing a fully natural process that creates what’s described as a unique hue of orange in the finished wine. Bottled at cask strength, Heaven’s Door secondarily aged its mature Kentucky bourbon for almost a year in Vino de Naranja Casks, imparting what they feel is a subtle sweetness, dark amber color and a multi-layered flavor profile.
