What you are looking for in a Gran Reserva cava is the tertiary aromas that emerge over a long period of ageing as a result of the autolysis produced by the yeast (which disintegrates), that adds all its features, aromas and properties over the 5 years of ageing. What we also seek to achieve is for the wine to retain the primary aromas of the grapes from which it has been made, as a Gran Reserva cava with only tertiary aromas will lack liveliness.
