Quinta das Maias, situated in the foothills of the Serra da Estrela in the Dão region, boasts a history dating back to 1893. The estate's name is derived from the local term "Maias," referring to the Weaver's Broom flowers that proliferate around the vineyards and bloom in May. For a significant period, the grapes from the estate were vinified at the neighboring Quinta dos Roques under a cooperative agreement that began in 1992. Quinta dos Roques was one of the pioneering estates in the Dão to focus on producing high-quality varietal wines. This philosophy has influenced the approach at Quinta das Maias. The estate transitioned to certified organic viticulture in 2007, underscoring a commitment to environmental stewardship.

The vineyards at Quinta das Maias are located at a high altitude of approximately 600 meters, a factor that contributes to the freshness and acidity of the grapes in the generally warm Dão climate. The soils are predominantly granite-based, a region characteristic that imparts a distinct minerality to the wines. The estate encompasses around 25 hectares, with a significant portion planted with vines that are now over two decades old, alongside more recent plantings. The planting strategy includes vertical row orientation, an innovative approach in the Dão aimed at optimizing sun exposure and airflow. The estate is dedicated to cultivating unique Portuguese grape varieties, with a particular emphasis on Jaen (known as Mencia in Spain), Touriga Nacional, Alfrocheiro, Tinta Roriz for the reds, and Malvasia Fina, Encruzado, Cerceal, and Gouveio for the whites. This focus on indigenous grapes reflects a desire to express the specific terroir of the Dão.

Quinta das Maias has embraced organic viticulture since 2007, a testament to their commitment to sustainable practices. This involves farming without synthetic pesticides, herbicides, or fertilizers, promoting a healthy vineyard ecosystem and enhancing biodiversity. The estate's high-altitude location naturally reduces disease pressure, supporting its organic approach. The name "Maias" itself, tied to a native plant, reflects a connection to the local environment. Their dedication to organic farming is a core value, aiming to preserve the land for future generations.

The winemaking at Quinta das Maias is overseen by Luís Lourenço, with his son also now involved in the business, ensuring a continuity of their philosophy. Luís Lourenço is considered a leading figure in the Dão, known for his methodical approach and control over all aspects of the winemaking process. The wines are crafted to express the estate's unique terroir, with fermentation often carried out using indigenous yeasts to further reflect the local environment. The white wines are noted for their floral character and strong minerality, possessing good aging potential. The red wines, particularly those based on Jaen and Touriga Nacional, are known for their freshness, vibrant fruit, and silky textures. The winemaking philosophy emphasizes minimal intervention, allowing the quality of the organically grown grapes and the distinctive terroir to shine through in the final wines.
