Old Tom Gin is a style of gin that originated in England during the 18th century. It is characterized by its slightly sweeter flavor compared to other gins, such as London Dry Gin. This sweetness is often achieved by adding sugar or other botanicals, making it a popular choice for cocktails. Historically, Old Tom Gin was often sold from wooden barrels or through a cat-shaped sign, which is how it got its name. Today, it is enjoying a resurgence in craft cocktails, with bartenders using it in classic drinks like the Tom Collins and the Gin Fizz.
