Furst von Metternich Trocken

[winepoppi]

My knowledge of German wines is almost nil. I recently was given a split (375ml) of this wine as a gift. Can someone assist, since any description is in German, with the following:

1. Type of grape?
2. Is this a bubbly?
3. What temperature to serve at?
4. What is a food pairing?
5. Approximate cost?
6. Why no vintage on label?

Thanks in advance for any help.
