It was made by the SA Brewing Company I believe. Now called Lion Nathan after a kiwi takeover, before they in turn were taken over by the Japs, Kirrin.

Duff Beer as made by SA Brewing, was not named after the Simpsons cartoon beer if I remember rightly. However the yanks threatened legal action for trademark infringement of a trademark class, ie beer, where they had never made any beer, never sold any beer, and never traded in beer in this trademark jurisdiction. A cartoon beer is not a real beer. However in TM matters money on legal bills matters and they withdrew their Duff Beer.

Does the Duff Beer have any Simpson's references on the packaging?

I like James Boag Premium as well.

I also will buy Coopers Sparkling Ale or Pale Ale.

I wouldn't ever bother with a XXXX or Vic Vomit Bitter.

I also wouldn't bother with a Hahn, since they were no longer a boutique winery back in the 80's or 90's. Made by an American Brewer in Sydney, called Dr Chuck (Hahn) back then. Now it is mass produced swill.

I am being unpatriotic nowadays and enjoy a Danish Carlsberg.
