What is the recommended ratio for flavored martinis?

The recommended ratio for flavored martinis often leans towards a 2:1 proportion of vodka (or gin) to flavored liqueur. This means for every two parts of the primary spirit, there would typically be one part of the flavored liqueur. This balance allows the drink to maintain its essence as a martini while imparting the desired flavor from the liqueur, ensuring it is not overly sweet or overwhelmingly flavored.

In a 2:1 ratio, there’s enough base spirit to provide the characteristic strength and character of a martini, while the flavored liqueur adds the unique twist that defines the drink's flavor profile. This ensures a harmonious balance between the spirit and the flavor component, making it enjoyable without losing the martini's core identity.

While other ratios like 1:1, 1:2, or 3:5 could be valid depending on individual preferences or specific recipes, they may not deliver the optimal balance that many bartenders recommend for flavored martinis in terms of strength and flavor integration.
