Adelantado Gran Reserva is a Spanish wine vinegar classified as Vinagre de Jerez Gran Reserva, produced by Páez Morilla in Jerez de la Frontera, Andalusia. It reflects the local tradition of producing and ageing sherry vinegar, with its quality and origin certified by the relevant Regulatory Council.

Made from Palomino Fino wine, it is aged for more than ten years in American oak casks using the traditional criaderas y soleras system. During maturation, it develops aromatic complexity through compounds formed during ageing and aromas drawn from the oak.

It displays a clear, brilliant mahogany colour with orange highlights, accompanied by a complex bouquet with notes of vanilla and nuts. The palate is intense and full-bodied, with a pronounced structure and a pleasant, lingering finish in which acidity harmonises with balsamic nuances. Its distinctive character makes it suitable for use in small quantities as a finishing touch or in dressings that allow its aromas to stand out.
