After the death of Willy Drube in 1952 and the migration of his descendants to West Germany, production was continued at Bad Lauterberg in the Lower Saxon part of the Harz mountain range. From 1972 onwards, Schierker Feuerstein was also produced again at the original place in Schierke, East Germany by a "Volkseigener Betrieb" ("Publicly Owned Operation", VEB), part of a larger beverages combine ("Getränkekombinat") based in Magdeburg.
