 Partially due to unauthorized Duff beer in the country, Fox announced plans to sell official Duff beer in Chile starting in early 2016, with plans to expand elsewhere in South America and into Europe.Producing a real Duff beer will allow Fox stronger trademark protections of the Duff name; as a fictional product, it is more susceptible to piracy.Since 2006, Rodrigo Contreras, from Guadalajara, Mexico is setting up a business with the purpose of selling Duff beer.
