The best-kept secret of Francisco Costa, better known in the football world as 'Costinha', and António Boal, of Costa Boal Family Estates, a red wine from old vines in Trás-os-Montes, which has been given the name 'Secret 6'.

A 3.5-hectare plot in Mirandela, Trás-os-Montes, where the harvest is marked by manual harvesting, careful sorting of the berries and prolonged aging in new French oak barrels.

Intense ruby color of great depth, aroma of enormous complexity marked by notes of red fruit and balsamic minty, in the mouth it reveals a harmonious balance throughout, showing a wine of structure and character with great persistence, ending with a finish of unparalleled class.
