Every year the Schloss Blutenburg hosts a (white) wine fest in the courtyard with wine, wine, wine, food and more wine.
It's easy to go as a group, stake out a place in the courtyard with a picknic blanket and enjoy the wine on the first day - luckily a public holiday. It lasts through the weekend, and is normally really crowded - so go early.
It's an easy bike ride, and through the fields on the way back if you plan your route properly. Public transport is also easily doable with the bus.
