Piedmont
The best wines of Piedmont are considered by many wine lovers to be some of the best wines of the world. These are the gems of Barolo and Barbaresco. But there are others made in this spectacular area as well, especially from Dolcetto and Barbera.

And here’s a map that was put out year ago by an importer named Kobrand, but I can’t find the original source on their website anymore. So I’m dropping it here, but note that it’s from them. (I like this map a lot because it shows where Alba is in relation to small Barbaresco and bigger Barolo.)
