If you want to buy a “genuine” bottle of Duff beer, you’ll have to travel to Mexico, Argentina, Colombia or Chile where the bootleg Simpsons beer is a hot seller.
The Duff dearth north of the border has only made fans more desperate. Online message boards buzz about where to find Duff. On eBay, an empty bottle of Duff beer from Argentina sells for $14.99; a decal off the Colombian product is being offered for $8.99.
At Rock Garden, a bar in Bogotá, Duff commands import prices — about $5.50 a bottle — even though it’s brewed in the nearby city of Medellin.
Duff Sudamerica, the Chilean producer hopes to sell $750,000 worth of the brew this year alone—but it seems likely that their efforts will eventually be thwarted by Fox and Groening, who has gone after Duff imitators in the past.
Groening fears that selling Duff beer, especially in the states, would be “tantamount to pushing alcohol on minors.”
