Main article: Classification of wine
Regulations govern the classification and sale of wine in many regions of the world. European wines tend to be classified by region (e.g. Bordeaux, Rioja and Chianti), while non-European wines are most often classified by grape (e.g. Pinot Noir and Merlot). More and more, however, market recognition of particular regions is leading to their increased prominence on non-European wine labels. Examples of non-European recognized locales include Napa Valley in California, Willamette Valley in Oregon, Columbia Valley in Washington, Barossa Valley and Hunter Valley in Australia, Central Valley in Chile, Vale dos Vinhedos in Brazil, Hawke's Bay and Marlborough in New Zealand, Okanagan Valley and Niagara Peninsula in Canada.Some blended wine names are marketing terms, and the use of these names is governed by trademark law rather than by specific wine laws. For example, Meritage (sounds like "heritage") is generally a Bordeaux-style blend of Cabernet Sauvignon and Merlot, and may also include Cabernet Franc, Petit Verdot, and Malbec. Commercial use of the term "Meritage" is allowed only via licensing agreements with an organization called the "Meritage Association".
