I am a little confused about the word "Troken" as it pertains to the various
levels of German wine. I understand that it means "dry" in its simplest of
forms but can there be a "Wine X" and a different "Wine X"- that is troken?

More specifically, I recently picked up some Donnnhoff Riesling Spatlese
Schlossbockelheimer Felsenberg "Troken." Is this the same 95 point Donnnhoff
Riesling Spatlese Schlossbockelheimer reviewed by Pierre Rovani in TWA #151?

If it is a different wine, I assume it to be of lesser quality but am not sure
why it may be so; and if it is the same wine, is it common for some retailers
to use the word "troken" and others to just omit it all together? ...Very
confusing.

Any help would be apprecieted.

Thanks,
Jason
