Joubertin
Grape probably originated in Isère department. It can still be found in Savoy, and it is also known in Argentina and Hungary.
Based on genetic analyzes in Montpellier (Hérault), it comes from a natural intraspecific cross between Peloursin and Persan.
It is part of the vine appellations Vin de Savoie for the department of Isère only. It gives a full-bodied wine, neutral, often with good acidity.
It has very long been associated with other grapes, bringing color and balance.
