Buck (Mule)

(n.) Falling under the umbrella of Coolers, this family of drinks distinguishes itself by the addition of ginger ale as the fizzy component to a base of spirit and citrus juice, served over ice. The citrus is often left in the glass. Thought to have originated in near-parallel with the Rickey in the late 1890s, the most famous example of this category is the Moscow Mule, a relatively late addition to the canon with an invention date in the 1950s.
