The tuferas of Briñas

The more traditional cellars, known as “calaos” or “caves”, dug into the earth and sometimes into the rock itself, needed a solution so that the carbon dioxide gas emanating during the fermentation of the grapes, known as “tufo”, would not be stored inside them. On the hill in the Bodegas district, these small ashlar stone constructions stand out as chimneys, the “tuferas”, used to ventilate the cellars. They date from the 19th and 20th centuries.
