📍 Dão

Dão is a wine appellation in north-central Portugal, in the Beira Alta region, in the districts of Viseu, Guarda and Coimbra. It is a granite plateau ringed by the Serra da Estrela, Caramulo, Buçaco and Serra da Nave mountains and crossed by the Dão and Mondego rivers. The region was demarcated in 1908, and in 2025 it had 9,834 ha of vineyards.

Granite makes up 97 % of the soils: they are poor, acidic and drain well. The mountains hold back moist air from the ocean and continental winds. Winters are cold and rainy, summers very hot and dry; rainfall is 1,200–1,300 mm a year, 80 % of it from October to April. Most vines grow at 400–500 m, and there are spring frosts.

A law of 18 September 1908 first set the boundaries of Dão, and the regional commission calls it Portugal's first demarcated region for non-fortified wines. The current rules are Portaria 246/2014: seven subregions, alcohol from 11 %, yields of up to 80 hl/ha for red and rosé and up to 100 hl/ha for white, and red is aged for at least 8 months. The “Nobre” mark requires grape juice with a potential alcohol of at least 13 % for red.

According to IVV data for 2025, the most planted varieties are Jaen (19.3 %), which the regulations also call Mencía, Touriga Nacional (19.0 %) and Tinta Roriz, that is Tempranillo (15.2 %). The main white variety is Encruzado (6.8 %), followed by Alfrocheiro, Baga, Bical and Malvasia Fina. In 2024 Dão produced about 13.2 million l of appellation wine.

Why it matters to you. Dão on the label means wine from the granite plateau, and a subregion name narrows down the place. “Nobre” means riper grapes. The current rules set no compulsory share of Touriga Nacional, so look for the varieties on the bottle.
