Bubbles

The effervescence of wine refers to the formation of bubbles (perlage) after opening a bottle of wine, resulting from the release of carbon dioxide. Carbon dioxide is a gas at room temperature, but it dissolves very easily in aqueous solutions—which is essentially what wine is. Opening the bottle releases the gas, whose bubbles create the foam typical of these wines. In sparkling wines and spumanti, the carbon dioxide bubbles (also called perlage) create the foam, enhance the aromas and the brilliance of the color, and reinforce the sensation of freshness on the palate characteristic of these wines. The ideal bubbles are fine, numerous, and persistent. They create a fine foam, more fleeting in semi-sparkling wines and more persistent in quality sparkling wines, especially those made using the classic method. Deviations from these ideal conditions (sparser, coarser, or short-lived bubbles) are considered a negative factor in the evaluation and scoring of the wine under review. The abundance, fineness, and persistence of the bubbles in the wine are due not to pressure, but to the wine’s structure itself. At the lowest level of the structure scale is distilled water. If supersaturated with carbon dioxide, it immediately releases all the gas in a tumultuous manner when the overpressure is removed. As the amount of dissolved substances in the wine increases—and thus as the wine’s structure and complexity increase—physical properties such as density, viscosity, and surface tension ensure that the release of bubbles after opening the bottle occurs continuously and gradually. At the same level of overpressure, a classic method sparkling wine with extended aging will have more numerous, finer, and more persistent bubbles compared to a younger, lighter sparkling wine. Quality sparkling wines can be produced using two methods:

The Classic Method (traditional, champenoise): used to produce Champagne and the highest-quality sparkling wines, this method involves a second fermentation of the wine in the bottle.
Charmat (Martinotti) method: characterized by shorter production times and lower costs, this method involves the wine undergoing a second fermentation in a pressure tank.

Metodo Classico pairs wonderfully with fresh seafood and fish dishes. It’s important to remember, however, that the more flavorful the dish, the more assertive the sparkling wine should be. A simple yet excellent pairing is with scampi or smoked salmon. The iodine in the fish finds a perfect match in the characteristic acidity of the bubbles. It pairs well with all cured meats, but Metodo Classico and culatello is a truly excellent pairing. As an aperitif and to accompany appetizers; paired with desserts, especially those made with yeast and cream (the bubbles help “cut through” the richness of the dessert), excluding those with more intense and complex flavors, such as chocolate, and ice cream, both due to the temperature and the strong fruit aromas and texture in the case of cream-based desserts.
