Daniel Veit was my hero last post! Thanks!
I'd also add to his post that Grüner is fairly thick skinned which yields a fair amount of phenolic density and texture to the wines. It's also generally has a high pH considering the white wine spectrum.
This week: Valtellina Superiore DOCG
Where is this? What is the climate like? What do they grow?
Fairly young as far as DOCG history goes; Valtellina Superiore DOCG was granted in 1998 and Sforzato di Valtellina in 2003
