El Maestro Sierra

El Maestro Sierra dates its foundation to 1830, when José Antonio Sierra, a master cooper, established his own wine business in Jerez de la Frontera. This history is symbolised by the traditional label of the house, which depicts a fox pursued by mounted hunters — the fox representing the craftsman seeking a place in a trade dominated by wealthy merchant families, the horsemen evoking the powerful bodegueros who controlled the industry.

The winery remains a small, independently owned house at Plaza Silos 5 in central Jerez. It is currently headed by María del Carmen Borrego Plá, daughter of Pilar Plá Pechovierto, who managed the house for more than four decades until her death in 2020. Ana Cabestrero combines responsibility for winemaking, cellar management and commercial direction, and her work has been central to maintaining the traditional character of the house while expanding its international recognition.

El Maestro Sierra preserves the identity of a traditional almacenista-style producer. Restrained intervention, careful maintenance of the soleras and limited production remain fundamental to its philosophy.

The portfolio includes Fino, Amontillado, Oloroso, Medium, Cream and Pedro Ximénez. The international reputation of the house rests particularly on a group of exceptionally mature wines drawn from very small soleras. Amontillado 1830 is described by the producer as having more than forty years of average ageing. Oloroso 1/14 is drawn from a fourteen-cask solera and presented with an estimated age of approximately fifty years. Oloroso 1/7 comes from an even smaller seven-cask system and is described as approximately eighty years old. The collection also includes a very old Palo Cortado and a Pedro Ximénez de Anticuario. Age figures substantially exceeding the official minimums required for VOS or VORS certification should be understood as producer estimates based on the history, movements and concentration of the soleras.
