There are a lot of cocktails named after the boroughs of New York City, and five of them have gained recognition over the years.
A Bronx consists of gin, dry vermouth, and orange juice. It was formerly listed as an IBA official cocktail and was ranked as the third most famous cocktail in the world in 1934. A pre-Prohibition cocktail, the Bronx appears in the 1908 book The World's Drinks and How to Mix Them. Some accounts say the Bronx originated in Philadelphia and was later popularized in New York. Others say that it was invented by a bartender in the Waldorf-Astoria Hotel. According to Alcoholics Anonymous founder Bill W., the first drink he ever had was a Bronx cocktail, after which he became an alcoholic.
A Brooklyn consists of rye whisky, dry vermouth, maraschino liqueur, and Amer Picon. In this regard, it is similar to a Manhattan, but with a specific type of bitters (instead of the several that can be used in a Manhattan) and the notable addition of maraschino.
The Brooklyn was popular in the early 20th century and largely fell into obscurity after Prohibition. It began to regain popularity at the end of the 20th century.
A Manhattan is a cocktail composed of rye whisky, sweet vermouth, and bitters, typically served in a cocktail glass. Of the five drinks, it is the only one considered one of "the unforgettables" on the IBA list of official cocktails. It is also listed as one of the six basic drinks in The Fine Art of Mixing Drinks.
The Manhattan is said to have originated at a banquet hosted by Lady Randolph Churchill at the Manhattan Club in the late 19th century.
Staten Island is the only borough without a cocktail that bears its name directly. A Staten Island Ferry is named after the ferry that carries passengers between the boroughs of Manhattan and Staten Island.
