Looking for a "Bacchus"

[DWtsn]

I am looking for a wine(s) from the Mosel-Saar-Ruwer region of Germany. It is a Qualitatswein, "Bacchus". I cannot find this anywhere in the US that I've been, although I have found a few other wines from the same region.
Also, can someone tell me if the "Bacchus" would be the sweetness, or taste of the wine, or is this the grape itself?

Bacchus is a white wine varietal resulting from the cross (Silvaner x Riesling) X Muller-Thurgau. The wines range in all styles, but are not known for exceptional quality.
