THE WINEMAKING
Once the grapes are ripe, they are picked and placed in 20kg boxes, which have holes bored in them in case of rain. They are then taken to the winery and processed that very same day.
The first part of the process involves lying the bunches of grapes on the inspection table where between 4 and 6 people select the grapes rejecting those which are not up to standard. Depending on the year and the vineyard rejection can rise as high as 20% of the total.
An elevator then takes the grapes up to the ‘stem remover’ where they are detached from the stem which holds a high amount of tannin (these are not removed for Port Wine). A small amount of sulphur (disinfectant and antioxidant) is added. From there they are transferred through pipes to the ‘lagar’ or wine press.
After two days, during which the evolution of the fermentation is checked twice a day, the ‘must’ is transferred to stainless steel vats where the fermentation process continues until it’s over.
Both the ‘lagares’ and the vats are equipped with a refrigerated water circuit in a chiller which guarantees that the fermentation is kept at a temperature below 30ºC . We do not use industrial yeasts. A few days before the vintage starts, we pick some grapes, destem them, foot trod them and wait for the fermentation to start spontaneously. In French it’s called ‘pied de cuve’. The fermentation starts naturally as the grapes have natural tannins.
On the day the grapes enter the ‘lagares’ in the evening, a group of 10 men foot trod the grapes in the lagar for 3 hours.
This process has two phases. The first phase involves trodding at an almost military pace in which the men stand in a line, arms linked and move forward centimetre by centimetre, crushing the grapes against the granite with their feet. This goes on for an hour and a half.
At that point, the song ‘Liberdade’ (Freedom) is sung and for the next hour and a half the group trod at will. This operation will be repeated the following evening.
