As an expert sommelier and brewer, I can confidently say that a case of Champagne can contain either 6 or 12 bottles, depending on the size of the bottles. Let me explain in more detail.
In the wine industry, a standard case of wine typically contains 12 bottles, each with a volume of 750ml. This is true for most still wines, including red, white, and rosé varieties. However, Champagne, being a sparkling wine, often comes in larger bottle sizes.
The most common size for a bottle of Champagne is 750ml, which is the same as a standard bottle of wine. In this case, a case of Champagne would indeed contain 12 bottles, just like a standard case of wine.
However, Champagne is also frequently available in larger bottle sizes, such as magnums. A magnum of Champagne has a volume of 1.5L, which is equivalent to two standard bottles. Therefore, a case of magnum Champagne would contain 6 bottles, as each bottle is double the size of a standard bottle.
It's worth noting that larger bottle sizes, such as magnums, are often used for special occasions or celebrations. They can enhance the presentation and enjoyment of Champagne, as they allow for slower aging and development of complex flavors.
In my personal experience, I have come across both 6-bottle and 12-bottle cases of Champagne. The choice of bottle size often depends on the occasion, the preference of the consumer, and the availability of different Champagne brands and vintages.
To summarize, a case of Champagne can contain either 6 or 12 bottles, depending on the size of the bottles. A standard case of 750ml Champagne bottles would have 12 bottles, while a case of magnum (1.5L) Champagne bottles would have 6 bottles. Both sizes offer unique experiences and are suitable for different occasions. Happy drinking!
