"Schierker Feuerstein" is a herbal liqueur and digestif (35% abv), patented in 1924 by the local chemist, Willy Drube. The red-brown beverage is named after the red granite of the Feuersteinklippe, a tor-like rock formation nearby. After World War II the production at first continued in Bad Lauterberg on the western side of the inner German border, but was also resumed in Schierke from 1972 on as "Volkseigener Betrieb". After reunification the enterprises merged while the "Feuerstein" is still bottled at both locations.
