After obtaining the “musts” (unique denomination that receive in the area the wines already fermented alcoholically), the complex and long process of aging in the winery begins.
The wine is aged by the soleras and criaderas system, according to which the boots are mounted on platforms on top of each other according to their level of age. The casks containing the oldest wine are located on the ground, in the solera. When the wine is extracted from these casks for bottling, it is replaced with the wine of the next higher level (the first criadera), which in turn is refreshed with the second criadera, and so on until it reaches the last criadera that contains the younger wine or sobretablas.
Thanks to this unique genuine system of the Marco de Jerez, the youngest wines are methodically mixed with the older ones, year after year: these gain in freshness and youth and those obtain the body and solidity of their elders.
