For Czechs, their original Budweiser beer is more than a quaff. It's a piece of national identity. If could be sold off soon.Czech beer fans are nervous. The government is planning on turning the state-run brewery in Ceske Budejovice (Budweis) into a publicly-traded corporation. Officials insist the government would keep the majority of shares, but many doubt that. A sell-off would channel much-needed funds into the state coffers. One company keeping a close eye on the debate is InBev, the international brewing giant that is not allowed to trademark its US-based Budweiser brand in Europe.
