Ruusan Imperial stout was a strong, dark beer—or stout—that was originally brewed on the planet Ruusan. A thick, dark, alcoholic beverage, the flavor of this beer was described as warm, full-body, and similar to bitter chocolate. Many breweries throughout the galaxy had adapted the original Ruusan recipe to cater to specific tastes, including adding coffee or more chocolate to the formula. The Sleepy Watchman, a cantina on Corulag, served Ruusan Imperial stout on tap.
