José Cuervo Reserva de la Familia tequila Reserva de la Familia is the world’s first extra añejo tequila. Hand-selected from the private collection of the Cuervo family, each bottle is made using only blue agave harvested at the peak of its maturity after seven to twelve years of field growth, and aged in French and American oak barrels for a minimum of three years. Reserva de la Familia is best served in a glass, allowing its flavours, aromas and velvety flavour to be fully appreciated.
