Still while we're on the topic of beer... here's a link to a map of the Czech Republic that shows where breweries are located, essentially, a beer map: http://mapa.pivni.info/
It's interactive, thus click on any of the brewery names and you'll be brought to a page with additional info. Please note that the page is in Czech, but there will be a link directly to the brewery, and there you can select your preferred language.
Beer tour anyone?
