I have specific glasses for Mosel and Rhine Riesling, and they're shaped to transmit the bouquet well. And to reflect the culture. These have thick green stems, grooved.
You can possibly find correct glasses? If not, just buy conventional wine glasses, as you'd use for other white wines.
Which Mosel did you drink? Those bottled along the Mittel-Mosel by the Prum & Erben families tend to be the best.
If you drank Bernkasteler Doctor from the wrong glass, you have indeed committed an offense...of some sort! Ditto for really fine Wehlener-Sonnenuhr, etc.
I like these best in Late Harvest (Spatlese) grade. Auslese and sweeter grades are not for drinking with food. Just by themselves or maybe with fruit.
