Simply don't expect him to read *every* post in this newsgroup. A subject like "many wines at dinner at Suba" is not what would attire my attention, I am sorry to say.
The most probable spelling would be "Pfaffengarten" (garden of the {catholic] priests) or "Pfarrgarten" (parish garden), but I have never seen this bottling in Austria. Giving the alcohol level definitely might help: Up to 12 it's basic. 12.5 is intermediate. From 13.0 upwords our wine starts to be serious stuff.
Sorry not to be able to tell you more.
