Chenin Blanc Parentage Revealed

We wanted to go to the First International Chenin Blanc Congress held in Angers from July 1-3, 2019. July is really a bad time for wine growers. We couldn't really leave the vineyard at that time. Moreover, our offspring were gathering at the old homestead in mid-July, so it was truly out of the question. The next best thing is to read all about it. My husband recently sent me the links to the information attendees at the first Congress were privy to. I was keenly interested in the revelation of the parents of Chenin Blanc as written in this article 1er Congrès International du Chenin Blanc + La Paulée d’Anjou (30th June 2019) – tasting.¹
The Congress opened with the keynote address given by Jean-Michel Boursiquot announcing that Chenin Blanc’s missing parent had been identified. The following slide was in this article showing the relationship of Chenin Blanc with other grapes:

The slide was a little blurry to me so here is my attempt to reproduce it:

So, the news is out! The parents of Chenin Blanc are Savagnin and Sauvignonasse. I wanted to learn more about Savagnin and Sauvignonasse, so I went to the Grape Bible, written by J. Robinson, J. Harding and J. Vouillamoz.²
Savagnin

Savagnin blanc is an early budding and ripening variety. It produces small, sometimes very small bunches and berries. The grape can achieve high sugar concentration while maintaining good levels of acidity. Savagnin Blanc makes a full bodied, firm, ageworthy wine that is sometimes called Traminer.

Sauvignonasse

Sauvignonasse is a fertile, vigorous and productive variety. Sauvignonasse is a lightly aromatic variety also called Friulano in Italy.
Whatever their parentage, the offspring, Chenin Blanc is one wine that we really love! Almost half of our vineyard is planted in Chenin Blanc!
