London Dry Gin is a type of gin that is made using a specific set of ingredients and production methods. It is made from a base of grain, usually wheat or barley, and is then distilled with juniper berries and other botanicals. The gin must be distilled to a minimum of 70% ABV and must not contain any added sugar or other sweeteners. London Dry Gin is a popular choice for cocktails and is often used in classic drinks such as the Martini and the Gin and Tonic.
