What is the pour size for a classic martini?

The classic martini is traditionally known for its specific pour size, which generally falls within the range of 2 to 3 ounces. The correct choice of 2.5 ounces reflects a standard that bridges the expectation of a robust yet balanced drink. This volume allows enough space for both the gin or vodka and the vermouth, while also enabling the drinker to enjoy the cocktail’s aromatic qualities.

This pour size offers a satisfying portion without overwhelming the palate, which is essential for balancing the strong flavors of the spirit with the subtler notes of vermouth and garnishes like olives or a lemon twist. In professional bartending settings, the 2.5-ounce pour is utilized for its ability to yield a well-proportioned martini that complies with the classic structure of this iconic beverage.

Other pour sizes, while common in various contexts or adaptations of the martini, do not align with the traditional definition and presentation of a classic martini, making them less appropriate choices for this specific question.
