Doctor (The)
.Brown sherry, so called because it is concocted from a harsh, thin wine, by the addition of old boiled mosto stock. Mosto is made by heating unfermented juice in earthen vessels, till it becomes as thick and sweet as treacle. This syrup being added to fresh “must” ferments, and the luscious produce is used for doctoring very inferior qualities of wine. (Shaw: On Wine.)
