Currently on the shelves in Dunnes we have
BB Bürgerbräu, a Czech lager from České Budějovice (formerly Budweis). It makes it quite clear on the label that it is a real Budweiser beer, and that this is now an EU-protected geographical designation, à la Champagne and Stilton.
However, for all its concerns that a big nasty American corporation has stolen its intellectual property, Bürgerbräu still has the feel of a cheap knock-off, of Budvar. It has the deep rich golden-syrup colour of Budvar, and does a fairly good impression of that full malty Czech taste. But it doesn't quite go all the way to perfection, lacking the smooth drinkability of Budvar. I think I'd pay the extra to trade up.
Fair play, however, for the game attempt to take back the Budweiser designation. I notice a few new Bohemian lagers around in Ireland these days. Here's hoping they can turn this geographical designation issue into a real campaign.
