The private brewery Heinrich Reissdorf GmbH & Co. KG was founded in 1894 by Heinrich Reissdorf in Cologne. It produces a top fermented beer called Reissdorf Kölsch.

Since 1968, the brewery in Cologne has been advertising on Aachener Straße with a moving neon sign in which a male lifts a glass of Kölsch to his mouth at a 90-degree angle. As the glass is emptied, the man's body fills with Kölsch, represented by neon lights lighting up from bottom to top. The advertisement alternately depicts a male and a female person. As a landmark of Cologne, this is now a listed building.
