Can't find this German Wine.

[Ksilverb]

My cousin bought my grandfather a wine while she was in Germany. He really loved it but the only problem is we can't find the exact wine she bought him. On the bottle it reads...Riesling in large gold letters. In small black print it says 1997er Pfalz...under that it reads...Dirmsteinter Schwarzerde...Under that it reads...Qualitatswein...and so on....if anyone has any information on this specific wine i would appreciate it..thank you very much.
