Sherry vinegar (Spanish: Vinagre de Jerez) is a gourmet wine vinegar made out of sherries. This vinegar is produced in the Spanish province of C diz and inside the triangular area between the city of Jerez de la Frontera and the towns of Sanl£car de Barrameda and El Puerto de Santa Mar¡a, known as the “sherry triangle”. To be called vinagre de Jerez, by law, the Sherry vinegar must undergo aging in American oak for a minimum of six months, can only be aged within the “sherry triangle” and must have a minimum of 7 degrees acidity. Most Sherry vinegar is aged using the same solera system as the Sherry wines and Brandy de Jerez. The production and quality of sherry vinegar is monitored and controlled by the Consejo Regulador and Sherry vinegar has its own Denominaci¢n de Origen, which is protected by Spanish and EU law. The only other vinegars with similar protected designation of origin are “Aceto Balsamico Tradizionale” from Modena and Reggio Emilia in Italy and “Condado de Huelva” in Spain.
