Duff Beer is a fictional brand of Beer from The Simpsons. A parody of many American Lager Beers that were cheap and poor quality, it is the common favorite drink of Homer Simpson and his friends. In the Simpsons universe, the brand not only comes in regular Duff Beer but also has other variations made with different crops or higher quality ingredients than regular Duff Beer.
Despite being fictional, Duff Beer has been sold in real life, either illegally or officially approved by the companies that own the Simpsons.
