The head office is located at Quinta da Vista Alegre, in the heart of the oldest Demarcated Winegrowing Region in the world - the Demarcated Douro Region - in the Cima Corgo sub-region, just a few kilometres from Pinhão. The unspoilt and magnificent surrounding landscape, given its privileged geographical location, offers visitors breathtaking views of the Douro River.

Its points of interest are of outstanding natural beauty, in perfect harmony with nature, remaining etched in memory through a sharpened sense of sight - unique pleasures in the love of rurality, the scenery and nature itself.

The Quinta's vineyards have a long-recognised history of producing wine, dating back to the 19th century. This is the conclusion drawn from books specialized in strain typologies and from some of the abandoned terraces, known as "mortórios". At the start of the 1970s, the company changed from a sole proprietorship into a limited liability company under the name - Sociedade Agrícola Barros S.A..

In May 1998, the company changed its name to VALLEGRE -Vinhos do Porto, S.A., resulting from the merging of the names of two of its most important Quintas - Valle Longo and Vista Alegre - but retaining its markedly family nature that spans five generations.

Thus, VALLEGRE is a private, family-based, modern, entrepreneurial and dynamic company. Creativity, Innovation, Quality, Customer Satisfaction´s Principles, Well-being of employees and Respect for the Environment, are laid down in the Mission, Vision and Values of the Company.

The production of DOC (Controlled/Protected Denomination of Origin) wines continues to be its primary aim: DO Porto, DO Douro and DO Moscatel Douro of the highest quality which are nationally and internationally renowned. Nowadays, the wines are sold and enjoyed in over twenty seven countries and the countless prizes and distinctions achieved in several international competitions prove the excellence of our quality.
