In reference to wine making, "secondary fermentation" is a fermentation process occurring after primary fermentation. Following primary fermentation, the wine is racked to a secondary fermentation vessel, capped, and air locked. The wine is then allowed to ferment for several months. When the desired amount of sugar has converted to alcohol, the secondary fermentation is complete.
