Gamay Blanc Gloriod is an obscure French variety of white wine grape.
It is named after Émile Gloriod, who discovered it as a seedling; it was originally thought to be a white version of the Gamay grape.
At first it was thought to be a seedling of Gamay, and conventional ampelography linked it to the Melon variety, but DNA fingerprinting showed that along with Chardonnay and Aligoté, it is one of many grapes to be the result of a cross between Gouais blanc (Heunisch) and Pinot.
Gouais blanc was widely grown by the French peasantry in the Medieval ages.
Other Gouais blanc/Pinot crosses include Aubin vert, Auxerrois, Bachet noir, Beaunoir, Franc Noir de la Haute-Saône, Gamay, Melon, Knipperlé, Peurion, Romorantin, Roublot, and Sacy.
