In the "Roche Encyclopaedia Medicine" a variety is one of the subspecies subordinate varieties or varieties, which was formerly also referred to as a type .

From a botanical point of view, however, this is not correct, because, strictly speaking, variety may only be used for natural populations (wild forms), but not for cultivated forms. To avoid confusion, one can resort to the terms grape variety or variety. Among botanists, the term cultivar (an artificial word from "cultivated variety") is predominantly used, by which all cultivated varieties by man are to be understood.

At the wine Glossary contained varieties are often varieties, variants or Klonmutanten, by mutation have arisen. These differ externally in a few characteristics (eg in the berries colour, in the taste or in the leaf shape ), but are due to the (largely) identical genotypes Ampelographisch as identical Rebsorte. Significant examples of this are the three varieties of the Traminer, such as Pinot Noir. Pinot gris and Pinot Blanc, These are two grape variety groups, which in the genotype are not distinguishable. However, they are managed in practice as independent grape varieties.
