Beefeater Distillery Brixton, Peckham & South London

Beefeater, established in 1863, is the oldest gin distillery still producing in London. The company opens its factory to visitors on 90-minute tours, which guide you through the gin craze of the 18th century to the cocktails and prohibition of the 1920s and '30s via interactive iPad explanations. A short talk on the production process, in the shadow of the distillery's enormous stills, concludes with an expertly poured gin and tonic. Tours run on the hour throughout the day.
