When making a Manhattan, what is the first step?

When making a Manhattan, the first step involves determining whether the drink will be served straight up or on the rocks. This decision sets the stage for the entire preparation process because it influences the glassware used and the final presentation of the drink.

If served straight up, the Manhattan will be poured into a chilled cocktail glass, which enhances its visual appeal and drinking experience. Conversely, if the drink is ordered on the rocks, it will be made in an old-fashioned glass and served over ice, which affects the dilution and temperature of the cocktail.

By clarifying whether the customer prefers their Manhattan straight up or on the rocks, a bartender can ensure they are crafting the drink according to the patron's preferences right from the beginning.
