The Cosmopolitan has a crazy history building up to the drink we know today.
The Cape Codder could be called a jumping off point for the Cosmopolitan. The Cape Codder was just a highball with vodka and cranberry with a lime wedge. It was made in 1945 as a promotion for Ocean Spray cranberry juice. The elements are clearly there for a Cosmo to come about, but the style still had a way to go.
The Kamikaze is another drink that's sort of three-quarters the way to the modern Cosmo. It's vodka, triple sec, and lime. Throw in a little cranberry and there you have it. The Kamikaze has been served all sorts of ways, up, on the rocks, and namely as a shot these days. Neal Murray is one of many to claim to have invented the Cosmopolitan. He reportedly added some cranberry to a Kamikaze and one of his customers remarked, "How Cosmopolitan." This was back in '75.
The exact origins of the cosmopolitan, as we know it, are a bit up to speculation. A drink named the cosmopolitan did exist in the 1930's, but it used gin, Cointreau, lemon juice, and raspberry syrup. The base Cosmo as we know it probably came around in the mid to late 70's. There are numerous claims as to who first made it up. Toby Cecchini might have made up the current recipe at the Odeon in '88. The cosmopolitan with flavored vodka came about when Absolut was testing out Citron in Miami and a bartender by the name of Cheryl Cook in the mid-80's. Another story of its origin comes from Miami, this one from 1989 again as a plug for Absolut. There are also numerous murmurs of it being created in the 70's by the gay community in Provincetown Massachusetts, coincidentally where I used to vacation every summer, and probably spread to San Francisco or vice versa. Reportedly, however, the Cosmo of the gay bars was a ghastly drink with well vodka and Rose's lime and grenadine. In its later iterations, it began using fresh juice and more premium ingredients.
