The exact origin of the martini is unclear. Numerous cocktails with names and ingredients similar to the modern-day martini were first seen in bartending guides of the late 19th century.[5] One popular theory suggests it evolved from a cocktail called the Martinez served at the Occidental Hotel in San Francisco sometime in the early 1860s, which people frequented before taking an evening ferry to the nearby town of Martinez. Alternatively, the people of Martinez say the drink was first created by a bartender in their town.[6] Another theory links the first dry martini to the name of a bartender who concocted the drink at the Knickerbocker Hotel in New York City in 1911 or 1912.[7]
But it was Prohibition and the relative ease of illegal gin manufacture that led to the martini's rise as the predominant cocktail of the mid 20th century in the United States. With the repeal of Prohibition, and the ready availability of quality gin, the drink became progressively dryer. In the 1970s and 80s, the martini came to be seen as old-fashioned and was replaced by more intricate cocktails and wine spritzers, but the mid-1990s saw a resurgence in the drink and an explosion of new versions.
Some newer drinks include the word "martini" or the suffix "-tini" in the name (e.g., appletini, peach martini, chocolate martini, espresso martini), however, these are simply named after the cocktail glass they share with the martini and do not share any ingredients in common, and therefore should not be considered variants of the martini.
