Unlike many drinks that started out as fads, the Cosmo rapidly ascended into the pantheon of classic cocktails. While several bartenders seem to have experimented with the recipe, no single inventor has laid claim to creating this drink.

Since there are a number of twists on the basic recipe, as well as variations, you will need to try numerous cocktail lounges to find the Cosmopolitan that suits you. Once you have found it, ask the bartender what proportions he or she uses. Then, by all means, tell other bartenders your preferences before ordering: more vodka, lime, and so forth. This is also an essential cocktail for the home bartender.

You will find the Cosmopolitan in swanky bars and posh nightclubs, at elegant soirées, or on afternoons by the club pool. The Cosmopolitan is also known to go head-to-head and drink-to-drink with the Martini at high-powered business luncheons. Be advised to refrain from ordering a Cosmopolitan at places named Bubba’s or Hog Heaven.

Unlike the Martini, there is very little debate over whether a Cosmopolitan should be shaken or stirred. The consensus is that shaken is the only way to go, so you will need a good cocktail shaker to make this at home. Also, stay away from cranberry juice that is overly adulterated with other juices. Any lemon-flavored (citron) vodka works well for a Cosmopolitan.

The Cosmopolitan is always served neat. The rim of the glass may be rubbed with lime juice and then coated with sugar.
