The History of the Tom Collins
At its core, the Tom Collins is a classic gin sour cocktail that’s lightened with soda water, transforming it into a spritz-style drink.

A Collins, in general, is a sour-style drink made with a spirit, sugar, and citrus, served in a tall glass over ice and topped with soda water – essentially a boozy sparkling lemonade.
The exact origins of the Tom Collins are debated. Drinks historian David Wondrich suggests it likely evolved from the gin punches that were popular in the early 19th century. One common tale credits John Collins, a bartender at Limmer’s Hotel in London, with popularising the drink. Whether Collins invented it or simply brought it to a wider audience remains unclear. Early versions of the cocktail were often made with genever or Old Tom gin, which eventually led to the name “Tom Collins” replacing “John Collins” in association with the drink.
