What is a Red Eye coffee?

A Red Eye coffee is specifically defined as regular brewed coffee with a shot of espresso added. This combination enhances the flavor and strength of the standard coffee, giving it more caffeine and a richer taste. The espresso's robust characteristics complement the brewed coffee, resulting in a unique beverage that appeals to those seeking an extra kick in their morning routine or coffee break.

In this context, the other choices do not accurately represent what a Red Eye coffee is. For instance, espresso served with frothy milk focuses on a different type of coffee preparation, emphasizing creaminess rather than the combination of brewed coffee and espresso. Cold brew coffee mixed with hot water is a method of adjusting the temperature of cold brew and doesn't involve espresso. Lastly, brewed coffee with chocolate syrup describes a sweetened variation that lacks the espresso component altogether, further differentiating it from a true Red Eye coffee.
