Aubin vert

While often confused for the Côtes de Toul grape Aubin blanc, DNA analysis in 1999 showed that Aubin vert was the result of a crossing of Gouais blanc with Pinot (an ancestor vine to Pinot noir).

This makes the grape a half-sibling to Aubin blanc (a cross of Gouais blanc and the Jura wine grape Savagnin) but full sibling to Chardonnay, Aligoté, Gamay and Melon de Bourgogne.

[1] In 1999, ampelographers at the University of California, Davis confirmed the parentage of Aubin vert as being the product of the prolific Pinot x Gouais crossing which is responsible for several grape varieties including Aligoté, Auxerrois blanc, Bachet noir, Beaunoir, Chardonnay, Franc Noir de la-Haute-Saône, Gamay Blanc Gloriod, Gamay noir, Melon de Bourgogne, Knipperlé, Peurion, Roublot, and Sacy grape varieties.

[2] Aubin vert is an early ripening variety that tends to produce grapes with very high acid levels.

[1] Aubin vert is grown almost exclusively in the Lorraine region of northeast France where it is an authorized grape variety in many of the wines produced in the Moselle, Meurthe-et-Moselle and Meuse departments.
