Since 1865, this spicy, earthy aperitif has been known as “ouvre l’appétit” - the key to the appetite. Serious in its role as an aperitif, and then popular with sportsmen, Bonal became an early sponsor of the Tour de France. It is made by an infusion of gentian, cinchona (quinine) and renowned herbs of the Grande Chartreuse mountains in a mistelle base.
