Bairrada is located north of Coimbra and south of Aveiro, between the Atlantic Ocean and Serra do Bussaco and Serra do Caramulo. This region has approximately 9000 hectares of vineyards spread throughout flat or low-slope areas in clay-limestone soils. The climate is temperate, with summers softened by a strong maritime influence and with long, cool and rainy winters.
The region was demarcated in 1979 with Denominação de Origem Controlada da Bairrada, but since 1890, the region has been producing sparkling wine using the classical method as the oldest sparkling wine producing region in the country. Still wines also assume great importance in the region, where white, rosé and red wines are produced. Grape marc spirit (aguardente) is also traditional in the region.
Baga is the main red grape variety in the region. Other red varieties are Alfrocheiro, Bastardo, Cabernet Sauvignon, Castelão, Jaen, Merlot, Syrah and Touriga-Nacional. Among white varieties, Arinto, Bical, Cerceal, Chardonnay, Maria Gomes (Fernão Pires) e Rabo de Ovelha are the most traditional, with Maria Gomes, Bical and Cerceal being standouts.
