The Val d'Aosta is Italy's smallest region in terms of both vineyard area and wine production. The difficult, alpine terrain favors small scale, quality driven winemaking, as many growers are working small plots of land where everything has to be done by hand. Independent wineries tend to be tiny, and much of the wine is made by co-ops, which are generally of higher quality than in most of Italy.
The region's isolation and low production can make the wines hard to find outside northwestern Italy, but a few importers bring in small amounts to the US. They are well worth seeking out.
The region has only one DOC, but there are several sub-regions producing very different styles of wine.
