What ingredient is often used in an Espresso Martini?

In an Espresso Martini, freshly brewed espresso is a key ingredient that defines the cocktail's unique flavor profile and character. The use of fresh espresso not only provides the drink with a rich, bold coffee flavor but also contributes to its texture and overall drinking experience. This ingredient is essential because it introduces the vital caffeine kick that many drinkers seek, particularly in a cocktail intended to be enjoyed as a pick-me-up or after-dinner drink.

While other ingredients may complement the espresso—like chocolate liqueur or vodka—they do not replace its crucial role in making an Espresso Martini distinct. The freshness of the brewed espresso is what separates this cocktail from others that may use coffee flavorings or syrups, emphasizing the importance of using high-quality, freshly prepared coffee to achieve the best possible result.
