Pinot blanc and Pinot gris are actually mutant versions of pinot noir, according to a study by French scientists.

The research reveals the colour variations in the Pinot family of grapes are due to genetic mutations which selectively switch off the genes responsible for creating the red pigments known as anthocyanins.

Frédérique Pelsy and her colleagues from the Grapevine Health and Wine Quality research unit at INRA Colmar, France, published the findings in the journal PLOS Genetics.

The researchers studied 33 clones of Pinot noir, Pinot gris and Pinot blanc.
