A number of works of fiction have incorporated into their world the existence of beverages, which may create a sense of the world in which the story takes place, and in some cases may serve to advance the plot of the story. The product may serve as a stand in for brand names, and in that capacity may be a vessel for mockery of the marketing culture associated with brand name products (e.g., Duff Beer from The Simpsons; Buzz Beer from The Drew Carey Show). In science fiction, beverages from alien races may enhance the sense of a futuristic society (e.g. Romulan Ale in Star Trek).
