in a solera or solera system, a group of barrels from which wine is periodically drawn off to refresh another criadera or solera. Each criadera represents a scale in the solera system. When wine is drawn from the solera for bottling, it is replaced by wine from the first criadera. The first criadera is then replenished by the second, and so on, with the average age becoming progressively younger in each criadera. Wine drawn from the youngest criadera is replaced by sobratabla wine, and the solera and the criaderas that feed it make up the scales of a specific solera.
