Yeah, he was quite clear on "the beer Americans call Budweiser"...
When Adolphus Busch came to th US ~175 years ago, Germany as we currently know it didn't exist (long story, I'll get to it later if necessary) and a section of the then Austro-Hungarian empire (in modern Czech Republic; then ~75% Czech, ~20% German speaking, er~5% other) was famous for their beer (Budweis was the German name for the town, Budweiser would be German, referring to someone from Budweis).
As Busch was primarily trying t o sell to the large German immigrant population in that area of the US, he chose Budweiser as a name that they would associate with a good beer.
Under the Soviet block, then Czecheslovakia turned the local breweries into a state run business, sold in East Germany under the German name, elsewhere unf]der the Czech name. When the Iron curtain fell, they started distributing it as Budweiser throughout Europe. US Bud (Anheuser Busch at the time) sued, and a settlement was reached where it could be sold as Budweiser in Europe (with the American beer sold as Bud) while everywhere else, they needed to use the Czech name.
