Denomination (also pure variety) for a wine that has been made from 100% of a single grape variety. If other grape varieties are also involved (even if only slightly), one cannot speak of "varietal purity", although the term "varietal purity" is also used colloquially for a clearly dominant grape variety. However, the term is not regulated by wine law. Within the EU, however, there is a wine-law regulation for the naming of grape varieties on the label. If a single grape variety is indicated there, its proportion must be at least 85% (in the USA or Australia, for example, only 75%). The remaining 15% can be supplemented by other varieties but do not appear on the label.
