The back label certifies the quality and control of each bottle and allows the wine to be tracked, as well as providing additional information on the type and category of the wine. The DO León ensures exhaustive controls to guarantee quality.
The neck label provides consumers with extra information on the type of wine in question (gran reserva, reserva, crianza, rosé, red and white). This includes the vintage, thereby certifying the wine’s age. The serial number on the label certifies its origin and production.
