Which beer is meant to be garnished with lime?

Dos Equis is traditionally garnished with lime, making it the correct choice among the options provided. This practice originates from the beer's Mexican heritage, where lime enhances the flavor and is a common accompaniment to many Mexican beers. The citrus note adds a refreshing contrast to Dos Equis' taste profile, which can include hints of malt and hops.

While Yuengling and Malibu might be enjoyed without lime, they do not typically have the same expectation or tradition associated with a lime garnish. Yuengling is an American lager known for its rich amber color and slightly sweet taste, and it is generally served without any garnish. Malibu, often associated with rum rather than beer, is not relevant in the context of beer garnishes. Thus, Dos Equis stands out as the choice that aligns with the customary serving style of being garnished with lime.
