The production region of the wines protected by the "JEREZ-XÉRÈS-SHERRY" Denomination of Origin and that of "MANZANILLA-SANLÚCAR DE BARRAMEDA" is located in the southern tip of Spain. The so-called "Sherry triangle" is formed by the cities of Jerez de la Frontera, El Puerto de Santa María and Sanlúcar de Barrameda, although the Denomination of Origin also includes land in the municipalities of Chipiona, Trebujena, Rota, Puerto Real, Chiclana de la Frontera and specific areas of Lebrija.

Within this production region, one part with its white organic loam (albariza) is traditionally called "Jerez Superior". This area includes the best "pagos" (boroughs) of El Puerto de Santa María, Jerez de la Frontera, Sanlúcar de Barrameda, and Trebujena. The rest of the demarcated region, known simply as "Zona" is formed by clayey and sandy soil, the majority of which are in the boroughs of Chiclana de la Frontera, Chipiona, Lebrija, Puerto Real and Rota.
