Piemonte
The Piemonte DOC, established in 1994, is a catchall for any wine made in the region of Piedmont (Piemonte). As there are no IGT wines in this region, that means that there are many types of DOP wines that cover every spectrum of wine produced in the region. Quite often, a producer will use the Piemonte DOC designation for a wine that is made outside of the DOC or DOCG rules; an example being a Nebbiolo that is blended with another grape, meaning it cannot be labeled as a Barolo or Barbaresco.
While there are a few examples available in the region, wines with a Piemonte DOC label are not seen much outside Piemonte.
