warriors from Plesse Castle approached Hardenberg Castle under cover of darkness, to take the Hardenbergs by surprise. Before the invaders could take positions, a wild boar began to squeal loudly, warning the Hardenberg army in time to see off the attack and prevent a siege. From that day, the head of a black wild boar - or Schwartz Hog - has been the family crest of the Hardenberg family, and later of their business and its products. "The liquor with the head of a boar" ("Der Korn mit dem Keilerkopf"). References Hardenberg family Alcoholic drink brands
