The modernization carried out in the 1940s was marked by the transformation of cellar space into industrial, vertical deposits of white and red wines and, from the 1960s onwards, collections of great historical and heritage value were created, resulting from the closure of some of JNV's warehouses.

The museum legacy today appears to be a well-preserved memory of the modernization carried out in the 1940s, when the Olival Fechado farm complex was acquired by the National Wine Board from the heirs of José Eduardo Raposo de Magalhães, during which period the cellar space was transformed into industrial, vertical deposits of white and red wines, according to the model of Abel Pereira da Fonseca.

A set of collections of great historical and heritage value was created from the 1960s onwards, following the closure of some of J.N.V.'s warehouses, resulting in the largest and most complete National Wine Museum.

The Museum's collection has an important collection of more than 10,000 movable pieces, of types as diverse as: oenology, ethnology, traditional technology, industrial archeology, graphic, plastic and decorative arts.

The Museum is identified by the Chamber as the most complete museum collection in the country on the wine theme.

The Museum underwent a period of closure and was reopened in 2013 by the City Council in 2017, which financed the renovation of the administrative building.

The museum collection is the most complete in the country in terms of wine, with aspects of the material culture of wine of unquestionable historical, scientific, industrial and ethnographic value ranging from the 17th century to the advent of the 21st century (A true Museum of Wine Culture).

The building will undergo a second phase of redevelopment that will begin in 2022 and be completed in 2023.

The most profound intervention included the building composed of the Distillery and the Armazém das Aguardentes, benefiting the connection between the two spaces, creating a museum complex that will have its own programming taking advantage of the four floors of the industrial building.

At Adega dos Balseiros, another of the buildings intervened, structural improvement works were carried out, particularly at the level of the roof, facade and accesses.

The wine cellar will maintain essentially the same configuration, but will benefit from a renewed capacity to host events and exhibitions, which were already the main uses of that space.
