One side effect of the cocktail renaissance is that every classic cocktail now has a plethora of interpretations. The Manhattan went reverse and swapped the proportions of sweet vermouth and rye. The Moscow Mule seems to be endlessly customizable with variations on garnishes, liquor type and proportions. This story is neither the time nor place to get into all of the Martini options. But if you like to follow the law, the U.S. government can clear everything up for you. The Alcohol and Tobacco Tax and Trade Bureau (TTB) legally defines 29 cocktails and seven cocktail twists.

The definitions can be found in chapter four of the TTB’s Beverage Alcohol Manual, published in 2007. It’s in the same section that defines types of distilled spirits based on class and type like “neutral spirits” or “whiskey.” Near the end of the chapter, the TTB defines recognized cocktails as such:

“[A] mixed drink that has gained trade and consumer recognition, containing one or more class(es) and/or type(s) of distilled spirits with flavoring and/or coloring materials.”

The Beverage Alcohol Manual fails to further elaborate how drinks gained enough “trade and consumer recognition” to be included. Some of the options seem odd, like the Apricot Sour and the Pink Squirrel, which are far from ubiquitous. Others, like the Margarita and all its added flavors (“Strawberry Margarita” is one called out by name), make sense. Google Ngram, a program that tracks how many times words are mentioned in books, shows that most of the drinks peaked in popularity in the 1980s with the exception of the Margarita, Daiquiri, Gimlet and Mint Julep. Ngram is far from a complete picture on what people are talking about, but it’s a useful tool to track cultural change and interest over time.

Regardless of how they’re chosen, they’re the ones that the government settled on. Here are the legal definitions of government-approved cocktails in the Beverage Alcohol Manual’s own words, punctuation and spelling.
