Designation (also pure variety) for a wine that has been pressed 100% from a single grape variety. If other grape varieties are also involved (even if only to a minor extent), it is not strictly speaking possible to speak of "single-varietal", although the term "single-varietal" 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 stated on the label, its share must be at least 85% (USA or Australia only 75%). The remaining 15% can be supplemented by other varieties, but do not appear on the label.
There is a vast number of sources on the web where one can acquire knowledge about wine. But none has the scope, timeliness and accuracy of the information in the encyclopaedia at wein.plus. I use it regularly and rely on it.
