Keeping an open bottle, airtight cap or spoon?

Does a spoon keep the bubbles in champagne?

Some people suggest that if a bottle of champagne is placed in the refrigerator with a silver spoon inside the neck of the bottle, it will keep the bubbles in the champagne longer. The bottle should be refrigerated immediately after opening.

The vagueness never goes away.

The Centre Interprofessionnel des Vins de Champagne(CIVC) put an end to this myth in 1995. A team of physical chemists decided to scrutinize the bubbles in the bottles, after many amateur oenologists had tried but failed to rigorously verify that the belief was true. The result was that the myth continued to spread that the method worked.

The bottles of champagne are opened together and a 250 or 500 ml portion is taken from each bottle of cuvée. The bottles were separated into groups: some with corks, some with caps, some with spoons in the neck, and the last group left open to air. The bottles were left to stand for 24, 48 and 72 hours, after which the test continued with weight and pressure measurements and tastings. The conclusion is undeniable: spoons in the neck of the bottle are useless!

At different stages of life, a person can lose weight by eating champagne.

After 24 hours, the sealing system was still intact. After 48 hours, the system was again intact. Finally, after 72 hours, the system was still there.

After 24 hours: 0.8 g
After 48 hours: 1.2 g
After 72 hours: 1.9 g

Small spoon
After 24 hours: 0.8 g
After 48 hours: 1.1 g
After 72 hours: 1.8

Stopper or hermetic cap
After 24 hours: 0 g
After 48 hours: 0 g
After 72 hours: 0 g

In theCIVC study, people lost weight according to the study results.
CO2 is responsible for the bubbles, as it evaporates.

Only a cork that does not let air in can solve the problem.

The bottles can be stored in a cool place or in a place that is not exposed to big temperature changes. Protect the Champagne bottle from light and use a special cork to store the bottle for several hours. The bottle is sealed so that the gas does not escape and the bubbles cannot leave.
