The grapes are vinified separately. Maceration at low temperature. Press juice yield of 50%. Fermentation of the musts at 16-18ºC with selected yeast. Base wines with an important acid component and a low pH appropriate for the long aging. After the bottling, the second fermentation and aging take place in our cellars located at 30 meters downstairs, at a constant room- temperature of 14ºC all year round.
