refers both to a dynamic system of maturation based on fractional blending, aimed at ensuring a consistency and continuity of expression, as well as the final stage or tier of that system, from which the wine is typically drawn for bottling. The best known—and generally most complex—examples of a ‘solera system’ are found in Jerez, where they are used to produce Sherry, but variations on it can be found elsewhere in Spain and beyond.
