Some bodegas have solera consisting of numerous rows of casks on top of each other so that some Fino and Manzanilla sherries may pass through fourteen stages in three years. After the Spanish wine has passed through the solera system it is tested and marked once more.
The marking system of palms or staves is principally intended for the cellar master and the buyers so we will not delve into this matter which is not of direct interest to the consumer. Just remember that the purest Spanish wines are sold as Fino while those Fino wines which eventually have developed more of the character of an Oloroso without the strength of this type of sherry, are known as Cortado. After the Spanish wine has aged it is decanted to clarify it and if necessary gently filtered.
