Different varieties of grape have differing aroma and flavour characteristics. Varietal character, however, while somewhat predictable, is not precise; variations occur, since virtually all vines are propagated by cloning. Some grape types are more prone to clonal variation, than others. The name of a particular varietal, therefore, should be considered a "surname" for vines that share a genetic history. Each varietal "family" may, in turn, include only a few or very many individual "clones", each with its own particular traits.
