Bouche de Bétizac is a French chestnut cultivar developed in 1962 by INRA at the station of Malemort-sur-Corrèze near Brive. It is a controlled hybrid between Castanea sativa and Castanea crenata (female Bouche rouge × male Castanea crenata CA04). This variety produces large to very large chestnuts. It has very good flavor for a hybrid. 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). Its fruit is bright, light chestnut-brown quickly turning brown and dark brown.
