The first glass poured after opening a bottle of sparkling wine.
The beautiful stream of bubbles, lively fizz on the palate, and fresh flavor make it a moment of pure pleasure.
On the other hand, carbonation gradually fades with time, and even with a dedicated stopper the wine can become almost still by the third day.
“If only that freshness of the first glass could last.”
Now, an item has appeared that aims to make that wish possible.
It is the pressurizing “DIONYSOS Champagne Stopper,” developed by Life Expert Co., Ltd.
We tried it to see what it can really do.
About the DIONYSOS Champagne Stopper

The DIONYSOS Champagne Stopper is a pressurizing champagne stopper developed and sold by Life Expert Co., Ltd.
A conventional stopper simply seals the bottle, but the DIONYSOS Champagne Stopper uses a distinctive mechanism: pressing its button pumps air into the bottle and raises the internal pressure.
This helps retain carbonation in a way that sealing alone cannot, allowing the sparkling wine to stay fresh for longer after opening, according to the company.
A high-quality stopper may keep carbonation for a while, but there is still a limit to what sealing alone can do.
Because the DIONYSOS Champagne Stopper actually pumps air into the bottle and raises the internal pressure, it is designed to maintain freshness for longer.
The mechanism is simple.

Each press of the stopper’s button sends air into the bottle, increasing the pressure inside. That pressure suppresses the release and rise of bubbles from the sparkling wine, helping prevent the carbonation from escaping.
- Replenishes and raises internal pressure
- Helps keep carbonation from escaping
- Keeps the wine enjoyable through the last glass
By combining sealing and pressurization, its patented structure is designed to preserve the appeal of sparkling wine.
Trying the DIONYSOS Champagne Stopper

“Honestly, if this really works, it is almost too revolutionary.”
We thought many readers might feel the same, so we actually used the DIONYSOS Champagne Stopper and checked how the carbonation and sense of freshness changed over time.

How long could the appearance and taste of that first glass be maintained?
Starting the test

The DIONYSOS Champagne Stopper is compact, so it does not take up much storage space.

Open the stopper’s wings and fit it onto the mouth of the opened sparkling-wine bottle.
Check that the bottle is firmly sealed.

Next, use the scale marked from 1 to 31 to set the date the bottle was opened.
That completes the setup.
Day 2

This is the sparkling wine on the second day after using the DIONYSOS Champagne Stopper.
The first surprise was the “pop!” when removing the stopper—it sounded almost the same as when the bottle was first opened on Day 1.
Usually, you hear a subdued “psss...” that signals the carbonation has faded, which can be a little disappointing.
There was no problem with the bubbles either.
The aroma still felt fresh and the palate remained sharp; it was hard to believe this was sparkling wine on its second day.
Day 3

This is the sparkling wine on Day 3 after using the DIONYSOS Champagne Stopper.
At this point it was hard to find words other than “surprising”: just like on Day 2, removing the stopper produced a “pop!” that sounded virtually identical to Day 1.
When the sparkling wine was poured into a glass, there was no noticeable change in the bubbles.
The aroma, texture, and flavor were also maintained, so the wine could still be enjoyed with a sense of freshness.
Incidentally, the carbonation was also largely maintained on Days 4 and 5.
For anyone who wants to drink just one glass of sparkling wine a day, this is an item we can genuinely recommend.
Recommended for Restaurants as Well as Individuals

The DIONYSOS Champagne Stopper is a useful item for sparkling-wine fans.
Its appearance is stylish, and because it is extremely light and easy to carry, it can also be useful at wine parties.
It is of course appealing to people who simply enjoy sparkling wine, but it may be especially useful for people working in restaurants and hospitality.
Because an opened bottle of sparkling wine can potentially remain usable for several days, it may also help reduce waste.
Another attraction is the price: ¥2,580 including tax for this level of performance.
If it sounds useful, this could be a good opportunity to try the DIONYSOS Champagne Stopper.
