Frankenwein, Weissherbst

[Wolfgang]

Hello!
While I was studying in Germany for a year, I came across some styles of wine that appealed to me, namely Franken and Weissherbst. I really haven't seen anything along those lines out here in southern California. Is there anything comparable, that anyone suggests I try? One of the more memorable days of my life was spent in Freiburg next to the cathedral eating Schinkenbrote and Kaesebrote with a bottle of Weissherbst. Any suggestions would be greatly appreciated! Thanks!
