Pradikat system

[barnesy]

I have been trying to figure out some details on the Pradikat system. I understand that its based on the sugar content of the grape. Now for the confusion...

Take for instance Urziger Wurzgarten, In a single vintage there can be spatlese, auslese, and other classifications from this site. Are there several sub-sites within the Wurzgarten site? Do they seperate grapes out based on surgar? Are certain parts of the wurzgarten site spatlese grapes, auslese grapes, etc? How do they do dat ting dat they do?
