Sherry vinegar (Spanish: vinagre de Jerez) is a gourmet wine vinegar made from Sherry. It is produced in the Spanish province of Cádiz and inside the triangular area between the city of Jerez de la Frontera and towns of Sanlúcar de Barrameda and El Puerto de Santa María, known as the "sherry triangle".
In the USA, to be called vinagre de Jerez, by law the Sherry vinegar must undergo ageing 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 vinegars are 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 Denominación 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
The style of sherry vinegar depends mainly on the grape variety used to produce the wine it is made from.
Sherry vinegar is used extensively in both Spanish and French cuisine. In 2008 France was the largest market for sherry vinegar.
Vinaigrette made from sherry vinegar is particularly flavourful compared to vinaigrette made from standard wine vinegar and matches well with many foods.
In Jerez de la Frontera a traditional dish is "Riñones al Jerez": lambs kidneys with a sauce made from sherry wine and sherry vinegar.
The best sherry vinegars have a deep, complex flavour and enhance the flavours in soups, stews, sauces, casseroles and dressings.
