In the case of a grape variety, this means that a rather slight deviation caused by mutation is to be understood, which is expressed, for example, by different berry colours, as in the case of Pinot with Pinot Blanc, Pinot Gris, Pinot Meunier, Pinot Noir and Pinot Précoce(early Burgundy). Such grape varieties are also called mutants or clone mutants. On the other hand, variety is understood as a variety in its own right. See also vine systematics and grapevine.
