Final answer:
The typical glass pour for sparkling wine is about 4 to 6 ounces and Moët & Chandon Impérial is an example of a champagne bottle. Fine sparkling wines and champagnes are carbonated through a secondary fermentation in the bottle, unlike less expensive sparklings which may be carbonated with CO₂ gas.
Step-by-step explanation:
The standard glass pour for sparkling wine, including champagne, is typically around 4 to 6 ounces. As for the name of one bottle of champagne, a classic example would be Moët & Chandon Impérial. The process through which champagne and other fine sparkling wines receive their effervescence is described by the traditional method where a secondary fermentation takes place inside the bottle. This fermentation is represented by the equation C₆H₁₂O₆ (aq) → 2C₂H₅OH(aq) + 2CO₂ (aq), where yeast converts sugars into alcohol and carbon dioxide, with the latter dissolving in the wine, creating the bubbles that are characteristic of sparkling wine.
Less expensive sparkling wines might instead be carbonated through exposure to high pressures of CO2 gas much like sodas and beer. This method is less labor-intensive and costly compared to the traditional method used for most fine sparkling wines and champagnes. In contrast, higher-end products like champagne go through this meticulous process, resulting in the luxury and quality associated with the beverage. An esteemed bottle label such as Dom Pérignon also utilizes such methods to produce its distinguished sparkling wine.
