Solera established in 1940. Produced by Emilio Lustau. L'Estornell Reserva Sherry Wine Vinegar is produced from choice Palomino Fino, the primary grape of Spain's renowned sherries. Aged in a solera of 24 oak casks, L'Estornell Reserva's aroma is pungent, its taste of nuts and ripe fruit delicately balanced by tangy acidity, cooked dishes and as a companion to L'Estornell extra virgin olive oil. www.vea.es. www.demedici.com.
