Liquor Pimm's No.1

Pimm, a farmer's son from Kent, became the owner of an oyster bar in the City of London, near the Bank of England. He offered the tonic (a gin-based drink containing quinine and a secret mixture of herbs) as an aid to digestion, serving it in a small tankard known as a "No. 1 Cup", hence its subsequent name. Pimm's began large-scale production in 1851 to keep up with sales to other bars. The distillery began selling it commercially in 1859 using hawkers on bicycles. In 1865, Pimm sold the business and the right to use his name to Frederick Sawyer. In 1880, the business was acquired by future Lord Mayor of London Horatio Davies, and a chain of Pimm's Oyster Houses was franchised in 1887.

Over the years, Pimm's extended their range, utilizing a number of other spirits as bases for new "cups". In 1851, Pimm's No. 2 Cup and Pimm's No. 3 Cup were introduced. After World War II, Pimm's No. 4 Cup was invented, followed by Pimm's No. 5 Cup and Pimm's No.6 Cup in the 1960s. In 1946, the corks were replaced by twist-off bottle caps.

The brand fell on hard times in the 1970s and 1980s. The Oyster House chain was sold and Pimm's Cup products Nos. 2 to 5 were phased out in the 1970s due to reduced demand. In 2005, Pimm's introduced Pimm's Winter Cup, which consists of Pimm's No. 3 Cup (the brandy-based variant) infused with spices and orange peel. In 2006, the Pimm's Company brand was bought by Diageo.
