from

The DO in which true SHERRY is made. It's located in southwestern Spain around the city of JEREZ DE LA FRONTERA. Although the DO zone encompasses a wider area, the core zone, called Jerez Superior, forms a rough triangle with Jerez de la Frontera at one corner and the towns of Sanlúcar de Barrameda and El Puerto de Santa Maria at the others. This area is rich with albariza, the white, chalky soil that produces the best grapes for fino and manzanilla (see SHERRY). This area's clay soil is called barro, which isn't quite as good as the albariza for such grapes.
