• a cask containing mature wine that has been aged and is ready to bottle
  • a method of producing wine that is a blend of different vintages using a graded series of casks. A proportion of the wine from the cask with the most mature wine is bottled, and replaced with younger wine from the cask containing the wine that is next in maturity, which in turn is refilled with younger wine, and so on. Once a solera is set up, all the casks will contain blended wine. The system is used especially in Spain for making sherry and also Málaga, Montilla and Alicante’s Fondillon, but also in Sicily for Marsala wines.
