Bouche de Betizac

Bouche de Bétizac is a French chestnut cultivar developed in 1962 by INRA at the station of Malemort-sur-Corrèze near Brive.

With Marigoule, it is the variety currently most cultivated in the French chestnut groves because it is very productive (3 tons per hectare on average).

In drip irrigated culture, in Bordeaux, the cumulative production at the age of 5 to 7 years can be between 21 and 40 kg per tree.

Bouche de Bétizac keeps its leaves into early autumn.

The nuts are also hanging on the tree for a long time and vibrators are sometimes used to aid the harvest.
