The soul of Carlos Serres wines is in their vineyard: Finca El Estanque. Covering 60 hectares in south-eastern Haro, it became a true landmark when espalier training was implemented in the early 1980s.

The training system increased leaf surface exposure, thereby enabling better ripening in all grape varieties and improved cluster aeration.

This allows for more environmentally-friendly growing practices and fewer treatments. It has mostly chalky-clay soils with a high gravel content, perfect for growing Tempranillo, Graciano, Mazuelo, Maturana Tinta and Viura, which are used to make their Reservas, Gran Reservas and the limited production Onomástica.

In a style that blends the history of this century-old firm with contemporary design, the winery preserves the historical and traditional heritage of its founder. Respect for their origins without relinquishing the Carlos Serres avant-garde style.

The wines are vinified in concrete tanks to ensure maximum preservation of varietal fruit expression. This is achieved through natural micro-oxygenation thanks to the porosity of the concrete walls
