Harzer cheese is a German sour milk cheese made from low fat curd cheese, which contains only about one percent fat and originates in the Harz mountain region south of Braunschweig. Harzer is often small and round, in which case it is called Handkäse or Taler, or cylindrical, in which case it is called Stangenkäse. Frequently, the small and round variety is sold in a cylindrical package, which is then called Harzer Roller.
