Budding cocktail historian Philip Greene has written all he can about author Ernest Hemingway and his legendary love of the drink with his engrossing read “To Have and Have Another: A Hemingway Cocktail Companion.”

So Greene has moved onto another integral subject in the cocktail world: the silky, sophisticated Manhattan.

Made with bourbon or rye whiskey, sweet vermouth and aromatic bitters, it “represents a watershed moment in cocktail history,” he writes in the new “The Manhattan: The Story of the First Modern Cocktail” ($19.95, Sterling Epicure). “For the first time, an imported, fortified aromatized wine known as vermouth modified the structure of the cocktail, adding balance, nuance, sophistication, and and sweetness to the base spirit.”

Once spirits and vermouth collided in this way, a whole new generation of cocktails — variations on a theme, as Greene puts it — was born, including the ones below. Sip them while you read Greene’s insightful book, full of historical facts, cocktail recipes and more.
