Wine containing carbon dioxide gas is called "champagne". Champagne is also a place name, located east of Paris.

As for the origin of "Champagne", there is such a legend: more than three hundred years ago, in the church of Reims, Champagne Province, France, a priest named Perignon used a variety of ingredients. The wine doesn't taste good. Later, he bottled the adulterated wine, sealed it with a cork, and sent it to the cellar. Unexpectedly, after winter, a miracle happened: the gas produced by the wine actually burst the cork, and an intoxicating aroma of wine came to the nostrils. Pour the wine into the cup and find that the color of the wine has become clearer, with countless small golden bubbles jumping around. The priest took a sip and couldn't help but exclaimed: "The angel came down to earth and sprinkled the wine with stars!" Thus, the champagne named after the local place became famous all over the world.

This legend corresponds to a famous saying in the wine city: wine is the child of the brewer. It can be seen that only a good brewer can make good wine. Of course, wines from different regions have different flavors due to different climates, soils, fruit types, and production methods.

In the Champagne region of the Marne Valley more than a hundred years ago, the terrain was flat and the climate was warm. The locals specialized in planting sweet grapes there and established a winemaking industry system in the provincial capital Chalon. The wine produced here is sweet and mellow, which is related to the maintenance of traditional craftsmanship. For example, when using a machine to press grapes, if the force is too high, the seeds will easily be crushed, but if the force is too low, the juice will not be squeezed out, and the taste will not be mellow, and the wine will contain black spots. Therefore, the Champagne region still mainly relies on the foot-pressing method to make wine.

During the harvest season, young men and women jump barefoot into the grape pressing room. As the music plays, they jump and step happily among the grape piles, completing the work of pressing juice while singing and dancing. The wine brewed using traditional methods is as smooth as silk, as greasy as oil, and has a mellow and fragrant taste.

The French government stipulates that only wines whose raw materials are taken from the Champagne region, contain 11 to 13 degrees of alcohol, are rich in sugar and have an aromatic taste are allowed to be named "Champagne".
