White wine grape · Vitis vinifera
An aromatic white wine grape from Argentina whose parentage, Listán Prieto (Mission) and Muscat of Alexandria, is reported by two independent references.
Plantgrape describes Torrontés riojano as originally from Argentina and, based on published genetic analysis, as a cross of Mission (Listán Prieto) and Muscat d'Alexandrie. The VIVC passport independently records the same two parents as confirmed by DNA markers.
The name Torrontés is shared by more than one cultivar. This profile covers Torrontés riojano only; the shorter aliases are included for search and do not mean the other Torrontés cultivars are identical.
Plantgrape describes the variety as productive, very vigorous and adaptable to a range of terroirs. That is a general cultivar description, not evidence of suitability, yield or water needs at a specific site.
