Beer is a circular, cup-shaped crater with a sharp-edged rim that has not been significantly eroded. The interior has a higher albedo than the surrounding lunar mare, which is usually an indication of a relatively young crater. A string of craterlets arc away from the rim to the southwest, known as Fossa Archimedes.
The mare to the east has a higher albedo than the surrounding surface, and this lighter-hued surface reaches to the base of the Montes Archimedes. To the southeast of Beer is a lunar dome that is of comparable diameter to the crater.
