Ganson is a red wine variety , a new breed between the Grenache x Jurançon Noir varieties . The crossing took place in 1958 by the French ampelographer Paul Truel in the Domaine de Vassal, a branch of the Institut national de la recherche agronomique of the University of Montpellier .
The clone 0534 is approved for commercial cultivation in France . Smaller experimental crops are known in Canada.

Ampelographic varietal characteristics
In ampelography , the habitus is described as follows:
- The shoot tip is open. It is hairy white wool and light green in color. The young leaves are hairy and copper-colored (anthocyanin spots).
- The leaves are five-lobed and clearly indented (see also the article leaf shape ). The stalk bay is closed lyren-shaped. The blade is bluntly serrated. The teeth are set medium-wide compared to other grape varieties.
- The conical to cylindrical grape is large (approx. 280 grams per grape) and has dense berries. The round berries are medium-sized (2.9 grams on average) and black and blue in color.
The variety sprouts early and is therefore sensitive to late spring frosts. It ripens around 25 days after the Gutedel and is therefore already considered to ripen late. Ganson is a variety of the noble grapevine ( Vitis vinifera ). It has hermaphroditic flowers and is therefore self-fruiting. In viticulture , the economic disadvantage of not having to grow male plants that produce yield is avoided.
