During the second French invasion of Portugal, the people of the current municipality of Boticas, for fear that their belongings would be plundered, hid their most valuable possessions, including wine, which was buried in the ground of the cellars, under the barrels and mills.
Later, when they recovered the goods, they discovered that the wine had acquired unexpected properties. A wine with low alcohol content and some gas, the result of a natural fermentation process during the time it was buried and whose conservation was benefited by the constant temperature and the absence of light. Because it was buried, it received the name of Wine of the Dead (Portuguese Vinho dos Mortos).
The Vinho dos Mortos is a testimony of the ingenuity and resilience of the people of the Barroso that has survived to the present day.
