Yeah, that is from an Australian bottle shop. (Thirsty Camel?)
I saw it for sale from a bar on Chapel St, Prahan (Melbourne) a couple weeks ago. Gotta go by and get some.
Its made in Mexico Cerveza Duff de México - Sitio Oficial
I think I read on Wikipedia something about this guy registered it in Mexico and FOX cant do anything about it (or I could be wrong - too lazy to check my own facts)
Don't think that's entirely true. I saw a Simpsons's documentary were a fan, in Chile, started mass producing his own Duff beer for sale. While his business was profitable, he was currently facing a lawsuit by Fox. I guess it also depends on the respective country's laws. I could imagine Mexico having bigger issues to worry about.
This was on the news a while back so my memory is fuzzy so what I say may or may not be true. I believe the reason it is not sold in the US is because it could be perceived as if the beer was being marketed to attract those under legal drinking age. I guess those over-reactions are more of a US thing.
I always thought that it was a common product all over the world, here in Italy you can find it (bottles or cans) just everywhere... And usually we are renowed for being the last wheel of the cart... :confused
