Whoops, my bad on semillon! (That is what happens when you don't google.) I'll add another Austrian oddity that I have tried in the past year, St. Laurent. From Jura, there is Savagnin which is used in Vin Jaune. I have only had Vin Jaune once. Pricey to put it mildly but the world of wine would be a poorer place without it. I have also tried Sercial, Verdelho, Bual, and Malvasia from Madeira. I'm not sure if I have had a Terrantez from Madeira or not. I also had some indigenous varieties from Corsica in the past year whose names escape me.

I don't really consider Gewurztraminer all that unusual, probably because I sell Gewurztraminers from Alsace and Ontario.
