One region of two, very distinct, sometimes culturally clashing, sub-regions: the Italian speaking Trentino sub-region in the south , and the German speaking Alto Adige (or Süd Tyrol) in the North towards Austria.
Differences aside, both areas offer white wines that are, in general, svelte and crisp. There are lots of really small producers (less than 400-500 cases total) and quality cooperatives (which isn't always the case in Italy). In fact, the only problem is that there's not that much wine to go around!
Trentino, the Italian part has a more temperate Alpine climate in general as it's lower in altitude; examples could be Teroldego Rotaliano DOC and the lesser known Vallagarina IGT. The Lago di Caldaro, and Santa Maddalena DOC around Bolzano, mark micro-climates from the Alpine regions of Trentino and the beginning of Alto Adige; after these regions, the slopes eek out on even higher on the Alpine mountains in Valle Isarco and Merano DOC.
The pure crystal fruit of Kerner, Riesling and Pinot Bianco grown here would convince anyone. But, the reds of the region deserve attention too: the age worthy and complex Lagrein has already made a name for itself, as has Teroldego. And, in the region, you see lots of people coming to producers at the holy grail of Pinot Noir.
But, to be simple about things, try the local red Schiava or white Pinot Bianco. The first is great for those summer nights on the deck, when you'd like a light red wine instead of a rose or white; the second is truly one of the regions great secrets that you can actually buy a case of.
