Located south of the town of Ancas, in the municipality of Anadia, in the privileged area of Figueira da Costa. Vinification of Sidónio de Sousa Special Cuvée Brut sparkling wine: the grapes are unloaded into the membrane press, where the tear must is extracted without pressing. The must is cooled for 24 hours, decanted and transferred to a stainless steel tank where it will ferment, with temperature control. After fermentation, the wine settles naturally in the tank, being cleaned at the end of the year, when it is prepared for bottling sparkling wine, with free yeast. The bottles of sparkling wine go to the cellar to carry out the 2nd fermentation in the bottle at a controlled temperature and in the absence of light. After fermentation, the bottles remain in the cellar, aging until regrinding and disgorgement without adding sugar, at which point the product is ready for sale.
