Zoigl is a type of German beer brewed in the Oberpfalz, eastern Bavaria, between Franconia and the Czech Republic. The name is believed to be derived from a Windischeschenbacher dialect pronunciation of the German word zeigen or Zeichen meaning "sign", the symbol used to advertise that the beer is available at an establishment. Its logo is composed of two component triangles represent the joining of six beer ingredients: the first triangle denoting water, fire and air; the second and inverted triangle denoting malted barley, hops, water.
