Carbonic maceration is a unique winemaking technique typically used to enhance the fruitiness and soften the tannins in light to medium-bodied red wines. In traditional wine production, grapes are harvested, destemmed, and crushed, and then yeast, either naturally present on the grape skins or added by the winemaker, consumes the natural sugars in the grape juice and converts them into alcohol. Contrastingly, in carbonic maceration, the initial fermentation process does not happen because of yeast but occurs intracellularly - meaning inside the grape itself. This technique involves placing whole, unbroken bunches of grapes into a sealed vessel filled with carbon dioxide. In this oxygen-free environment, the berries start fermenting from within. They use the available carbon dioxide to break down sugars and malic acid (a primary acid in grapes), producing alcohol and a variety of compounds that contribute to the wine's final flavor. During this process, polyphenols (better known as tannins and anthocyanins) migrate from the grape skins to the pulp, causing the white flesh to turn pink. Once the alcohol content reaches around 2%, the berries burst, naturally releasing their juice. At this point, a typical yeast fermentation process takes over to finish the wine. Carbonic maceration can completely change a wine’s style and flavor profile. If you’ve ever tried a red wine that bounced brightly out of the glass with an ultra-fruity bubble-gum aroma or crunched lightly with cinnamon, vanilla and earthy, stemmy flavors, light in color, low in acidity and tannins, and exhibits strong fruity aromas. These wines are generally intended to be consumed young. it’s likely you’ve encountered carbonic maceration.
