Vermouth is the most important aromatized wine in the world, and arguably the most indispensable ingredient in the history of the cocktail. Without it there is no Martini, no Negroni, no Manhattan. It is also one of the most misunderstood: kept for too long in a warm cupboard, poured in sad, flat dashes into otherwise excellent drinks, and rarely given the attention it deserves as a drink worth pouring on its own.
