Quinta de Saes, located in the Dão region of Portugal, is a notable estate renowned for its commitment to traditional viticulture and sustainable practices. The Dão region is celebrated for its unique microclimate, which is shielded by mountains that mitigate extreme weather conditions, allowing for the cultivation of high-quality grapes. This area features granitic soils that contribute to the distinct minerality and freshness of the wines produced here.

Alvaro Castro, a prominent figure in Portuguese winemaking, has been instrumental in establishing Quinta de Saes as a benchmark for the Dão. He manages the estate alongside his daughter, Maria, perpetuating a winemaking tradition that dates back to the 16th century. Castro's philosophy emphasizes a "slow-wine" approach, focusing on the use of indigenous grape varieties and crafting wines in the traditional Dão field blend style. This method allows for a true expression of the terroir, showcasing the region's hallmark grape, Touriga Nacional, known for its aromatic complexity and vibrant acidity.

Sustainability is a core principle at Quinta de Saes. The vineyards are cultivated without irrigation, relying on the natural rainfall of approximately 26 inches per year. This practice not only conserves water but also encourages the vines to develop deeper root systems, enhancing the quality of the grapes. The estate employs organic farming techniques, minimizing chemical interventions and promoting biodiversity within the vineyard ecosystem. By prioritizing these sustainable practices, Quinta de Saes not only preserves the integrity of its wines but also contributes to the overall health of the Dão region's environment.
