With its distinctive roof of adjoining barrel vaults, this wine cooperative has managed to undergo expansions without altering its original design, remaining a fine example of mid-20th-century architecture. Located in Vila Franca das Naves, next to the Beira Alta railway line, it was built to receive the bulk of the grapes produced by growers in the municipality of Trancoso and began operations in 1960. It reached peak production between 1990 and 2000, processing over nine million kilos of grapes, which made it the third-largest cooperative in the Beira Interior region. Like most others, its production fell sharply in the early 2000s and currently stands at between three and four million kilos.

Equipped with the necessary technology to enhance the value of its members’ grapes, the cooperative has undergone several upgrades over the years. Bottled wine only began gaining relevance around 2010 and has shown consistent growth in recent years. Benefiting from a privileged climate, the wines – both white and red – are generally of excellent quality and enjoy a strong reputation. As a result, they are regularly awarded prizes in both national and international competitions.

Wines are marketed under the labels Beira Serra (the most recognised), Portas d’El Rei, and Terras de Bandarra. The premium wines, all designated PDO Beira Interior, are bottled under the brands Bodas Reais, Boa Pergunta and Óptima Pergunta. In addition to white, red and rosé wines, the cooperative also produces quality sparkling and frizzante wines using the traditional method.
