An empty bottle of Reissdorf Kölsh left on a park, Cologne, Germany. Reissdorf is one of the most famous brands of Koelsh (traditional beer from Cologne). Since its foundation in 1894, the Privat-Brauerei Heinrich Reissdorf kept growing and boasts now a production of over 66 million liters a year. And no, I'm not being paid to say this, I just liked the beer :)
