What is the primary ingredient ratio for a classic dry gin martini?

The classic dry gin martini is characterized by a specific balance of ingredients that highlights the flavor profile of the gin while providing subtle complexity from the dry vermouth. The standard ratio for a traditional dry martini is typically 2 1/2 ounces of gin to 1/2 ounce of dry vermouth. This combination allows the botanicals in the gin to shine through, creating a refreshing yet spirit-forward cocktail.

Using this ratio, the vermouth serves as a delicate complement rather than overpowering the gin, which is essential for a dry martini. The ratio emphasizes the gin's characteristics, making it a preferred choice among gin enthusiasts. It is not just about quantity but about achieving the right flavor balance, making this option the quintessential recipe for a classic dry martini.
