So here's a grape I knew next to nothing about, the grüner veltliner from Austria. I got this bottle in a case of mixed whites so I can't give a price for it.
This bottle was unique in wines I've bought in that it has a beer/pop bottle-type cap, no cork or screw top.
I liked it and can see how Austrians enjoy drinking this on the terrace of an inn or bar. I would describe it as like a wine version of a hard cider, with apple notes to it. Wikipedia says it has stood up to world-class chardonnays, which I don't quite see because this didn't have the chardonnay body and is much more acidic.
A nice white for summer drinking, and everyone has a bottle opener!
