can anyone recommend a good winery within easy daytrip distance from munich?

There may be much better (closer) choices than this - - but if you get no other answers, you could make it to Bolzano-Trento-Alto Adige in a lengthy day trip. Maybe 2 and a half hours each way?

Seek out Teroldego Rotaliano, or any of various Austrian reds, as well... Blaufrankisch, Zweigelt, for example.

Best wishes,

Rex

thanks rex...appreciated...am going to research making this trip, in fact. best, jfm.

Go to Würzburg. You can easily reach it by train (2h 31m). It is a beautiful city with a splendid castle. The most famous wine is "Würzburger Stein".

Around Würzburg you will find beautiful small villages where they grow wine.

Munich is not in a German wine making area. Probably the closest major area is around Stuttgart.

German wine makers are good promoters of their product. There are plenty of web sites. Try googling for German wine.

I assume you know a Kabinett from a Spälese and a Riesling from a Kerner and a QmP from a Tafelwein. If not, your visit will be far more productive if you do some study before going. Know how to read a German wine label. There are web pages for that also.

This article will give you the basics on some German wines:
