As with all great classics, it is impossible to define with certainty the origin of the Cosmopolitan cocktail. In 1934, "American Traveling Mixologist" published the book "Pioneers of Mixing Gin at Elite Bars 1903-1933" in which we find the first cosmopolitan recipe with gin instead of vodka.
Cosmopolitans could also be attributed to Miami bartender Cherry Cook. In 1985 or 1986, she would have made a feminine cocktail but with rose's lime juice instead of cranberry juice.
With the ingredients we know today, the cosmopolitan was reportedly served as early as 1987 by San Francisco bar owner John Caine. There is also talk of Toby Cecchini, a bartender in New York, who in 1987 or 1988 replaced Cheryl Cook's ingredients with those we know today.
Already famous in America, the cosmopolitan has seen its popularity expand thanks to the broadcast of the soap opera "Sex and the city", in which the heroines can be seen on many occasions sipping cosmopolitans.
