Built in 1730, it is located in the small place of Cunhas.

In 2013, the brothers Jorge and Pedro Barroso, representatives of the current generation, aware of the weight of heritage and respect for memory, began a process of reconversion of the vineyard. Although the restructuring process was carried out using new systems for planting and driving the vines, the objective of the long generations that preceded them was preserved: to seek a balance between economic viability and the protection of the environment, without neglecting social obligations and cultural to the community in which it operates.

In 2017, from the selection of the best grapes from the 3.5 ha dedicated to the Alvarinho variety spread over 3 properties located between 100 and 400 meters, Casa do Barroso Alvarinho Reserva 2017 was prepared and bottled, presenting itself as the first wine to be marketed under its own brand and, therefore, as the first ambassador of Casa do Barroso.
