Duff Beer

Duff Beer is a brand of beer that originally started as a fictional beverage on the animated series The Simpsons, since then it has become a real brand of beer in a number of countries without permission or consent from its original creator, Matt Groening and has resulted in legal battles with varying results. It is also sold as an energy drink in the gift shop of The Simpsons Ride at Universal Studios.

It is Homer Simpson's beer of choice. It is a parody of stereotypical commercial beer: cheap, poor-quality, and advertised everywhere. The beer's official spokesperson is Duffman. While Duff Beer comes in several varieties, it is revealed on a Duff Brewery tour in "Duffless" that regular Duff, Duff Light, and Duff Dry are the same beer, although Homer and Barney apparently remain oblivious to the fact. A tasting room also contains several varieties that Barney stated they had not tried yet, including Raspberry Duff, Lady Duff and Tartar Control Duff. In "Homer's Odyssey", Duff is described as "The beer that makes the days fly by". In "A Tree Grows in Springfield," Homer asks for Moe's best beer, so Moe gives him a Duff Adequate. Fudd, a competitor to Duff, appears in the episodes "Colonel Homer" and "Lemon of Troy", the latter showing it being enjoyed by residents of Shelbyville, rival town to the Simpsons' home of Springfield. Consumption of Fudd however is alleged by bartender Moe Szyslak to have made hillbillies go blind.
