Martín Códax Espumoso has been made with a selected harvest at the beginning of September, ten days before the start date of the conventional harvest to ensure its freshness and balance. Prior to the elaboration using the traditional method (champenoise), the base wine was kept on its lees for three months. The tirage was done in October 2017. The second fermentation in the bottle was done slowly, controlling the temperature, obtaining a smaller bubble size perfectly integrated into the wine. It underwent aging for thirty months on its lees before disgorging, providing complexity in the aromas further favoring the integration of the bubble.
