MGM champagne stopper

Wine goods sold in KALDI, "MGM Champagne Stopper". It is an item that can temporarily store sparkling type wine such as champagne. made in Italy.


The price is reasonable at 540 yen (tax included), but how long can it be stored? I tried to verify!

How to use the champagne stopper

The cap part is designed to rotate around. Push this into the mouth of the bottle.




Hold the bottleneck between the two claws and fix it. It's OK if you press the cap part and snap it in.


How many days will sparkling wine last?

◆ Day 2

The next day, even if it wasn't as fresh as it was opened, the moment I removed the cap, the air rushed out. When I drank it, the flavor was a little off, but I felt the carbonic acid swashwa firmly.

◆ Day 3

On the 3rd day, the "pop" sound was a little quieter than on the 2nd day, but the taste was not much different from the 2nd day. I didn't feel the difference between the first day and the second day.

◆ Day 4

When you remove the lid, you can still hear a vigorous pop. The bubbling when poured and the squishy feeling when put in the mouth have weakened considerably, but they are still there. However, the impression that the sweetness is strongly left on the tongue because the carbonic acid has been removed.

◆ Day 5

Carbonation and taste are almost the same as on the 4th day. Is the flavor gradually decreasing?

◆ Day 6

When you open it, it becomes a "pop", but the impression that carbonic acid has decreased at once. The flavor has also dropped sharply.

◆ Day 7

There was almost no sound when it was opened, and carbonic acid was almost removed. It seems that the period of delicious drinking has completely passed.


So, I think it depends on the storage conditions and things, but if you use a champagne stopper, you can drink it deliciously for about 2 to 3 days. It's like 3 days. I think it will be useful when you can't drink all at once!
