James Bond called it the "Vesper," after the double agent he lusts after in
Casino Royale. After Bond was poisoned in
Casino Royale he always smells his drink you know this if you watched
Dr. No because
Sean Connery smells his Martini to see if its poisoned or not.
On his first trip to Jamaica to look for land, Ian Fleming went to a local club. There he was introduced to the “Vesper” cocktail. Fleming loved the name so much, he wrote the name on a napkin as to not forget it. This inspired him to name his Bond Girl in the novel Casino Royale, Vesper Lynd. Word for word, the drink Bond orders in the
Casino Royale book:
A dry martini, in a deep champagne goblet. Three measures of Gordons, one of Vodka, half measure of Kina Lillet. Shake it very well until it's ice cold, then add a thin slice of lemon peel.Very nice, 007!

James Bond's Champagne of Choice: 
It should be noted, however, that although the current film James Bond drinks Bollinger (a marketing deal with the producers of the film series), Bond originally preferred Dom Perignon, produced by
Moët et Chandon. But because it is a vintage champagne, it is only produced when the grapes are at their best. Currently, the vintage for Dom Perignon is 1999 (and it's no doubt the scarcity of the production that has encouraged the producers to switch). This exchange between Dr. No and Bond explains the agent's preferences, as he grabs a bottle to fend off Honey Ryder's abduction during dinner:
Dr. No: That's a Dom Perignon '55, it would be a pity to break it
James Bond: I prefer the '53 myself...
Bombed. James Bombed.

007's stunning alcoholic prowess often extendes far beyond the classic Vodka Martini and a bottle of Bollinger:
