There exists a deep cleavage in the taxonomy of cocktails that I learned about as I was starting out as a bartender: One major branch consists of the cocktails you shake, the other the cocktails you stir. Drinks like the daiquiri, margarita, and whiskey sour are made through the violent action of shaking, while the Manhattan, old-fashioned, negroni, and martini are gently stirred before hitting the glass. With few exceptions, drinks that contain opaque liquids like citrus juice and dairy are shaken, and drinks made exclusively with clear liquids, such as spirits, fortified wines, and bitters, are stirred. Stirring a cocktail preserves the silky texture of the components while chilling, mixing, and diluting them. For the most part, these drinks are considered stronger and more spirit-forward than shaken drinks, and the properties of the stirring process allow those characteristics to shine through.
