Langhe is a region in Cuneo Province of Piedmont. It is home to a number of world famous wine producing regions, including Barolo and Barbaresco and consists of hills.

The region is particularly interesting from the perspective of wine tourism because they make wine like this nowhere else in the world. The difficult but noble nebbiolo grape is used in Langhe to make two of the best wines in the world, Barbaresco and Barolo, "the king of wines and the wine of kings". There have been attempts to export the grape, but so far the resulting wine has failed to reach the quality of the nebbiolo wines of Langhe.
Other interesting red wines include barbera and the simpler dolcetto. White wines are not as famous, but among others arneis and chardonnay are produced. There are also unusual local varieties such as freisa, used to make a lightly sparkling red wine, and grignolino. The moscato grape is used to make above all a low-alcohol dessert wine.
There are few important sights. But as the region is hilly, it offers some great views. Good places to admire them are La Morra and the castle in Grinzane Cavour (housing the regional wine cellar and a restaurant).
If you are really interested in wine, it pays off to go visit a producer for a tour and a tasting. Like everywhere, visiting wineries in the Langhe is like visiting a working farm. It is a good idea to call ahead before you show up, but it may be possible to taste wine without an appointment at some wineries.
