Borba

Borba sits in the Serra de Borba mountains of Alto Alentejo, covering municipalities including Borba, Estremoz, Vila Viçosa, and parts of Elvas, Alandroal, and Monforte. The region occupies a limestone plateau at an average altitude of 416 metres, well above the flat Alentejo plains that surround it. This elevation makes Borba the second-largest subregion of the Alentejo DOC.

• Average altitude of 416 metres; all vineyards above 400 metres
• Located within Serra de Borba mountains in Alto Alentejo
• Municipalities of Borba, Estremoz, Vila Viçosa, and parts of Elvas, Alandroal, and Monforte
• Second-largest subregion within the Alentejo DOC

Borba experiences a Mediterranean climate with hot, dry summers and cold winters. The plateau elevation delivers cooler nights and morning dew, moderating the intense Alentejo heat. Annual rainfall of 750-850mm is notably higher than the Alentejo average, and the average annual temperature of 15.5-16°C is lower than most of its neighbouring subregions. These conditions preserve natural acidity in the grapes and contribute directly to the freshness and elegance that define Borba wines.

• Mediterranean climate; hot dry summers, cold winters
• Annual rainfall 750-850mm, above the Alentejo regional average
• Cooler nights and morning dew moderate summer heat
• Average annual temperature 15.5-16°C

The soils of Borba are defined by red calcareous limestone, with patches of red schist and black red schist across the plateau. The region is equally famous for its marble quarries, and marble deposits within the soil are a direct contributor to the mineral complexity found in Borba wines. This limestone-marble foundation sets the region apart from the more granite and schist-dominated soils found elsewhere in Alentejo.

• Dominant soil type: red calcareous limestone
• Patches of red schist and black red schist throughout
• Marble deposits directly linked to mineral character in wines
• Region famous simultaneously for marble quarrying and viticulture

Aragonez is the cornerstone red variety, producing wines with elegance, mineral character, and refined tannins. It is blended with Trincadeira, Alicante Bouschet, Castelão, Syrah, and Periquita, with reds making up approximately 70-75% of total production. White wines are produced from Roupeiro, Rabo de Ovelha, Perrum, and Tamarez. The combination of limestone soils, higher altitude, and elevated rainfall results in full-bodied reds with rich fruit, natural acidity, and a mineral complexity that distinguishes Borba from warmer Alentejo subregions.

• Aragonez is the dominant red variety; drives the region's signature elegance
• Red blending varieties include Trincadeira, Alicante Bouschet, Castelão, Syrah, and Periquita
• White varieties include Roupeiro, Rabo de Ovelha, Perrum, and Tamarez

Winemaking in Borba dates to the 1st century during Roman occupation. The region gained international prominence in the 17th century, making it the first Alentejo subregion to attract outside attention for wine quality. Phylloxera devastated the vineyards in the late 19th century, and recovery came through the 20th century via grafting techniques. The Adega de Borba cooperative was founded in 1955 and remains a cornerstone producer. Borba held IPR status before achieving full DOC recognition in 2003, becoming one of eight official subregions of the Alentejo DOC.
