Beck's Brewery, also known as Brauerei Beck & Co., is a brewery in the northern German city of Bremen. In 2001, Interbrew agreed to buy Brauerei Beck for 1.8 billion euros; at that time it was the fourth largest brewer in Germany. US manufacture of Beck's Brew has been based in St. Louis, Missouri, since early 2012. Since 2008, it has been owned by the Interbrew subsidiary of Anheuser-Busch InBev SA/NV.

Beck's logo with the key is based upon the city of Bremen's coat of arms, which contains a key that is attributed to the patron saint of the city, Saint Peter.

The Coat-of-Arms of the Free Hanseatic City of Bremen shows a silver key on a red shield. The key is the attribute of Simon Petrus, patron saint of the Bremen Cathedral, and it was first represented in the seal of the City of Bremen in 1366, after its liberation from the occupation by Prince-Archbishop Albert II, and later became the main element of the city's coat-of-arms.
