Old Tom gin is a style of gin that originated in England during the 18th century. It is sweeter than traditional London Dry gin, often made with added sugar or sweet botanicals. This unique flavor profile makes it a popular choice for classic cocktails, such as the Tom Collins and the Gin Fizz. The name "Old Tom" is believed to come from a wooden cat figure that marked gin distilleries in London. This style of gin fell out of favor in the 19th century but has seen a resurgence in recent years, appealing to both craft cocktail enthusiasts and gin lovers alike.
