Casa Agrícola Roboredo Madeira (CARM)

Casa Agrícola Roboredo Madeira, known as CARM, is a family-owned operation with agricultural roots in the Douro Superior dating back to the 17th century. The company was officially founded in 1913, though its modern winemaking era began in the mid-20th century. In 1966, Celso Madeira used modern machinery to plant the family's first large-scale vineyard on terraces, a technique that was a novelty for the Douro at the time. By the 1990s, the family transitioned from selling grapes to producing their own estate-bottled wines under the leadership of Filipe Roboredo Madeira, who focused on improving production quality and sustainability.

The estate manages approximately 200 hectares of vineyards located around the village of Almendra, within the Douro Superior sub-region near the Spanish border. This area is characterized by a harsh, dry climate and stony schist soils. CARM became a pioneer of organic viticulture in Portugal, achieving certification for its entire production in 1995. Winemaking is conducted at the Quinta das Marvalhas facility in Almendra, where head winemaker António Magalhães Ribeiro has overseen production since 2002. The technical approach emphasizes freshness through the use of thermal shock and fermentation in temperature-controlled stainless steel vats, although traditional stone lagares are still employed for specific lots.

CARM is best known for its organic Douro DOC wines, particularly the Reserva and Grande Escolha reds made from Touriga Nacional, Touriga Franca, and Tinta Roriz. The producer also crafts white wines featuring indigenous varieties like Códega do Larinho, Rabigato, and Viosinho, which are often picked at high altitudes to preserve acidity. A notable addition to their portfolio is a Touriga Nacional produced without added sulfur dioxide, highlighting their focus on low-intervention techniques. Alongside wine, the estate is a major producer of organic extra virgin olive oil, which regularly receives awards in international quality competitions.
