KLOVEO Champagne Stoppers - Patented Seal - Made in Italy - Professional Grade WAF Champagne Bottle Stopper - Prosecco, Cava, and Sparkling Wine Bottle Stopper

Excellent product, works very well, keeps sparkling wine bubbly.

Years ago, was gifted a couple of these, by the marketing rep for the Conegliano Valdobiadene prosecco region. They weren't available for purchase in the United States at the time. These have never leaked, never opened inadvertently, have held up to years of professional bar use, on catering events. These Kloveo's are the same as the ones I was gifted years ago. The pictures show the new Kloveo on the left, next to one of my originals, which has been in professional service for almost ten years. Bought the two pack, and the lock cage on one is not set quite straight. Seems to work fine, just not as smooth in use as it could be. Minor thing, I guess. Seals fine. I saw the reviews nothing QC issues. There's going to be manufacturing defects sometimes, with anything. It's frustrating, but these really are the most solid performing sparkling wine cap design I know of, and I've used most of them. My original set have been banged around a lot, and work as well as the day I got them. Occasionally, wine gets through the little vent hole in the silicone seal, and becomes oxidized. It's a pain to address, because there's no good way to rinse it out. My solution is hydrogen peroxide, wooden toothpick, and a pair of rubber or nitrile gloves. Chlorine bleach works too, but can oxidize the rivets on the swivel, and maybe weaken the hard plastic parts. It could also affect the flavor of the wine. Hydrogen peroxide breaks down into oxygen and water, has never caused a problem for me. I've had success with the drugstore hydrogen peroxide. Some non-chlorine bleach is just hydrogen peroxide, water, and citric acid, would also work well. It's basically twice the strength of the drugstore stuff. It's tedious to get the hydrogen peroxide into the silicone nipple, but it does bleach the issue, and you don't have to try to rinse it back out. It won't adversely affect the wine. These sparkling wine stoppers are well worth having. Best you can get, imo.

Perfect champagne stopper. Works great and looks nice too. Cannot complain great item. Seals great and it’s a very durable product

Used for my Lambrusco wine, kept it fresh with fizz for 3 days! Very easy to install / remove from bottle.

This is the best Champagne stopper to date that I have found. It does a very good job of sealing the open bottle and maintaining the bubbles and is very easy to use. The company warns you to be careful when removing the stopper from the open bottle in that it may pop off and launch powerfully into the air with a very loud pop, and they are so right! The warning is important for safety reasons (they suggest draping a dish towel or the like over the bottle & stopper before releasing the stopper and to prepare for the loud 'pop') and it is good they do so. The 'launch' and 'pop' are solid reflections of how well this stopper works! Not every bottle is as perfectly sealed, but in my experience 95% of the time they are. I am very pleased with this Champagne stopper.

This stopper works great. The second day it tasted as if I had just opened it for the first time. Only negative issue I experienced when opening the cap was when removing it made an extremely loud popping noise from the pressure build up. It hurt my ears pretty badly. Works great for keeping the bubbles in but brace your ears!!!! I took off 1 star because its not pleasant when opening. Even Louder than opening the cork itself.

Works good at sealing the prosecco and saving it for another couple of days. Maybe more. Haven’t finished the bottle yet. Haven’t checked to see if it is leakproof because the bottle is upright on the frig door. It’s a good product. Update: it’s been a week and still bubbly.

So easy to use. Keeps Prosecco and champagne fresh and bubbly. I’ve finally found the perfect stopper!

Ich habe den Verschluss schon mehrfach verschenkt und er ist einfach genial und sicher. Man kann angebrochene Flaschen auch liegend lagern. Ist definitiv sein Geld wert.

Seems to work great for keeping the bubbles in the prosecco

This is a quality sparkling wine closure at an affordable price. It does the job extremely well, and is very easy to use. I also like the fact that it maintains a low profile, as it does not sit high above the top of the bottle when closed. Super gift item. Very satisfied and would highly recommend.

This stopper performs exactly as described, and is great quality. Has that same POP every time I open it, as if it was the first pop of the cork. Very happy with my purchase. I got 2.

KLOVEOのシャンパンストッパーを購入して使ってみたところ、「もっと早く買えばよかった！」と思えるほど優秀なアイテムでした。イタリア製のしっかりとした作りで、特許取得済の密閉機構のおかげか、炭酸の持ちが抜群。翌日までしっかり泡が残っていて、開けたてのような美味しさが楽しめました。 これまでいろいろなシャンパンストッパーを試してきましたが、どれも翌日には泡が抜けがちでがっかりしていたのですが、KLOVEOは全然違いました。圧力ポンプも不要で、ただ差し込んでロックするだけのシンプル操作なのも◎。おしゃれなデザインも高級感があり、ギフトにもぴったりです。 正直、価格は少し高いと感じましたが、それ以上の満足感があるので納得しています。週末に妻とスパークリングを楽しむ我が家では、もう手放せない存在になりました。
