Fining is a method of clarifying wine via a fining agent such as powdered clay, whipped egg whites, powdered milk, or gelatin. As with filteringand centrifugation, fining has its share of detractors, who feel wine should achieve clarity naturally. If a winemaker chooses not to use a fining agent, the label may state that the wine is "unfined" or, more likely, "unfiltered and unfined."
