That's a good possibility. The Napa section in the average store is small and includes tons of crap that isn't worth packing to ship. I know the same thing happens in reverse, but this is terrible. Of anyone is looking for a bottle to hold onto, grab something Austrian. We have the only region the Grüner Veltliner is grown and it's getting popular world-wide. The problem is that we export a small percentage outside of Austria. Not too many places in the US import Austrian wine as it's difficult to get.
That being said, if you live in Illinois, Missouri, Oklahoma, Texas, New Mexico or Arizona, let me know! I'll be there in a couple of weeks and I'd be happy to bring extra bottles.
You sure it's not grown in Slovakia, Hungary, and maybe Czech? I could be wrong but I think it is. Granted, it's probably not up to a Domäne Wachau but I do think folks are making some there.
