What's in a name?

I saw the sign below at the Eggenberg Brewery in Český Krumlov and found it very interesting. For those of you who don't have any German it says "Budweiser from the Original Source", just as Pilsner Urquell is "Pilsner from the Original Source".

The sign goes on to state that this "Budweiser Urquell" is brewed at the Burgers' Brewery in Budweis, which is the German name for the modern city of České Budějovice. The Burgers' Brewery in Budweis, according to the sign was founded in 1795, some 60 years before the Bavarian Brewing Company was founded in the US - it was this brewery that would become Anheuser-Busch. Indeed the Burger's Brewery in Budweis, which is today the Budějovický měšťanský Pivovar - "Town Brewery of Budweis", is 100 years older than the makers of Budvar.

By the time the Bavarian Brewing Company had been renamed in 1860 the Burger's Brewery of Budweis had been selling under the brand name "Budweiser Bier" for over half a century.

According to Shakespeare, a rose by any other name would smell as sweet - the converse must also be true, call a beer made with rice what you will, it won't change the fact that it is dish water.
