Regulations govern the classification and sale of wine in various regions of the world.

Wines are usually named either by their grape variety or by their place of production. Generally speaking, European wines are named both after the place of production (e.g. Bordeaux, Rioja, Chianti, Cotnari) and the grapes used (e.g. Pinot, Riesling, Chardonnay, Merlot). Wines from everywhere except Europe are generally named for the grape variety. More and more, however, market recognition of particular regions and wineries is leading to their increased prominence on non-European wine labels. Examples of recognized locales include: Margaret River, Napa Valley, Barossa Valley, Willamette Valley, Cafayate, Marlborough, Walla Walla, Douro, Rioja etc.

Some blended wine names are marketing terms, and the use of these names is governed by trademark or copyright law, rather than a specific wine law or a patent on the actual varietal blend or process used to achieve it. For example, Meritage (pronounced to rhyme with "heritage") is generally a Bordeaux-style blend of Cabernet Sauvignon and Merlot, and may also include Cabernet Franc, Petit Verdot, and Malbec, while the dôle is made from the Pinot Noir and Gamay grapes. Use of the term Meritage is protected by licensing agreements by The Meritage Association.

Europe classification

France has an appellation system which ranges from Vin de Table ("table wine"), through Vin de Pays and Vin Délimité de Qualité Supérieure (VDQS) up to Appellation d'Origine Contrôlée (AOC)[24] and which is based on the concept of terroir[25] (or region of origin) and wine quality. Like France, Portugal also has a governmental classification based on the region of the grapes and the quality of the wine. Portugal is pioneer in the creation of the DOC ("Denominação de Origem Controlada" or AOC in Portuguese) by creating the Demarcated Douro Region and a system regulating its wine production and trade, by a royal charter in 1756 [1].Germany developed a similar system in 2002[26] though this has not yet developed the authority of the French system.[27] Spain[28] and Italy also have a classification which is based on a dual system of region of origin and quality of product.[29]


Outside of Europe

New World wine, that is wines from outside of the traditional wine growing regions of Europe, tend to be classified by grape rather than by quality or region of origin, though there have been subjective attempts to classify by quality,[30] most successfully by Langton's.[31]
