This term often causes confusion as it is used differently and often incorrectly in the relevant literature. According to "Duden", a variety (Lat. Varietas = subspecies or form, also race) within biological classification is a slightly deviating form of a species (Lat. Species). In the "Roche Lexikon Medizin", a variety is a subspecies subordinate form or type that was previously also called a type. A variant (deviation, subspecies, type) means a deviation from the comparison or standard type or norm (a slightly altered form of something). However, this term is not used in the context of the Botany order. In common parlance, however, there is hardly any distinction made between the terms variety and variant.
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.
