The local brewery, Würzburger Hofbraeu, brews excellent wheat beer Weissbier, which carries the name of a 1600s bishop of Würzburg, Julius Echter. Basically this beer is served for you in almost all the local bars, if you order a hefe.
Würzburg resides in the middle of Franconian wineland and Frankenwein is served in many places. You can recognize the peculiar shaped bottle, Bocksbeutel, easily.
