Varietal or generic wines?

Varietal wines

Wines produced from a single variety of grape are known as varietal wines. A wine bottle labeled with the name of a particular grape may contain a high percentage of that grape or it may be made up exclusively of that grape. A bottle of wine produced exclusively from a particular type of grape is described as containing 100% of that grape. The percentage of a grape variety needed for a bottle of wine to be labeled with the name of a particular grape varies from one country to another. In Argentina the minimum is 85%.

Bivarietal

All bivarietal wines are considered generic wines because they contain a mix of more than one variety of grape. However, not all generic wines are bivarietal. There are excellent wines which combine as many as thirteen varieties of grapes as in the case of Chateauneuf du Pape in France.
