1) Spanish name for vintage. The label may indicate how many years after the harvest the wine has been bottled. For example, "3 año" means that the wine was bottled in the third calendar year after the harvest. For example, for a vintage of 2015, this means that it was bottled in 2017.
2) A system rarely used today in the production of sherry. In contrast to the Solera system, the wine remains vintage pure (unblended).
