The grapes are vinified separately. Grapes are refrigerated before pressing (to avoid loss of aromas). Press juice yield of 50%. Static dewed at low temperature. Fermentation of musts at 16-18ºC with selected yeast. Base wines with an important acid component and low pH appropriate for the long aging. After bottling, the second fermentation and aging take place in our cellars located 30 meters underground, at a constant room- temperature of 14ºC all year round.
