The process of adding spirit to a wine. If this is done before completion of the alcoholic fermentation, as with Port, the unfermented sugars will cause the wine to be sweeter than would otherwise be the case. Added later, as is the case with Sherry, the wine will remain dry. In all cases the final alcohol content receives an obvious boost. The process is also used in the production of vin doux naturel.
