What are the names of each part of a champagne bottle?

The circle where the outer diameter of the bottle mouth is 29 mm is called Annulus, which is literally translated as bottle mouth ring in Chinese. This is an indispensable part used to secure the metal coil.

The aluminum foil wrapped from the mouth of the bottle to the neck of the bottle is called Foil. Its most important function is to keep the cork clean.

The elegant line that rapidly expands the bottle mouth from the smallest diameter to the largest is called a shoulder. The height, width and width of the “shoulders” even show the style of the winery from the side.

The correct name for the depression at the bottom of the bottle is Punt. The next time you hear someone pointing to the bottom of a bottle and saying "bottom", you can confidently tell them that only something like crystal is called "flat bottom".

The metal coil used to fix the cork is called a "Muselet", and the metal cap on the top is called a "metal cap".
