Spanish name (literally "education" = expansion) for a wine that matured for a certain time in oak barrels and bottle before it is allowed to go on sale. These wines must have matured for at least 24 months, including six months in oak barrels and the rest in the bottle. Renowned growers are often guided by the higher maturity of Rioja or. Ribera del Duero, In the fields of Penedès or Toro Many Crianzas are aged for at least 12 months in oak barrels; Wines with "only" 6-month aging are considered Roble or Semi-Crianza, even though they meet the local Crianza criteria. Even higher maturing times are available at the quality levels Reserva and Gran Reserva. With "Sin Crianza" (sin = without) a mostly young wine is called, which was not developed in the barrel.
