Here's a fun animated video by Reactions that should provide some timely trivia for this evening's festivities: Why is Champagne bubbly? Basically, unlike other wines, Champagne undergoes a second fermentation process that allows carbon dioxide to dissolve into the wine. Because a resting bottle of Champagne represents an equilibrium between the gas in the wine and the gas in the air between the liquid and the cork, uncorking the bottle "releases the gas and throws off the equilibrium." Another fun fact: Up to 600 chemical compounds contribute to the flavor of Champagne. Go, watch the explainer above.
