Gammel Dansk is a bitters liquor and was originally created to become a competitor on the Danish market to other bitters such as Underberg and Fernet Branca. It is matured with 29 types of herbs, spices and even flowers, making it similar to other stomach bitters, such as Peychaud’s Bitters or Jagermeister. These herbs and spices include angelica, star anise, nutmeg, anise, ginger, laurel, yellow gentian, Seville orange and cinnamon, and several others. The complete recipe is kept secret.
