International Gin and Tonic Day

International Gin and Tonic Day is observed every year on October 19. The day celebrates the gin and tonic, a classic cocktail known for its simple mix of gin, tonic water, ice, and a citrus garnish. Popular in the United Kingdom and many other countries, it remains one of the world’s best-known mixed drinks.

History of International Gin and Tonic Day

International Gin and Tonic Day was created in memory of Mary Edith Keyburn, whose family and friends honored her love of the drink after she passed away on October 19, 2010. The observance has since become a lighthearted occasion for gin and tonic fans around the world.

The drink itself has roots in the British presence in India. Tonic water originally contained quinine, which was used to help prevent malaria. Because quinine has a bitter taste, British officers mixed tonic with gin, sugar, water, and citrus, creating a drink that eventually became popular far beyond its original setting.
