title_body: Why is beer in Czech Republic so cheap?
upvoted_answer: It is in my opinion mainly thanks to low excise duty on beer in the Czech republic.
  
  Another factor is the fact that there are lower prices of almost everything in the Czech republic (I am talking mainly about local food and beverages).
  
  And last but not least, Czech republic is I guess second or third in the whole world in beer consumption, which means there is high level of demand for traditional czech beer, which allows producers to produce beer in large quantities.
