Emmentaler AOP Réserve is a cheese for connoisseurs. The first quality control sees suitable wheels being chosen for further maturation to achieve the Réserve quality. These wheels are matured for at least eight months and carefully treated in special maturation warehouses. They are matured at a temperature of 11 to 14 ºC and in an air humidity of over 90% (moist storage) to give them their strong flavour. Emmentaler AOP Réserve is also sold with other names referring to the length of the maturation period (e.g. Surchoix, Ripe, Mature,…).
