Pimm's No. 1 is a 25% ABV, gin-based British liqueur with a deep red color, featuring a secret blend of herbal botanicals, caramelised orange, and delicate spices. Created in 1840, it is famously used in the "Pimm's Cup" cocktail—a signature summer drink at Wimbledon—typically mixed with lemonade or ginger ale, mint, cucumber, and fruit.
