KLOVEO White Champagne Stopper - Made in Italy - Patented Seal - Durable Plastic WAF Bottle Stopper for Sparkling Wine, Prosecco, Cava

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.

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

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

When you can’t finish your entire bottle of sparkling wine, this champagne stopper is the best. After two days, it was like opening the fresh bottle.

This is hands down the best champagne stopper ever created. I’m always shocked when restaurants aren’t using this and are still using the stupid cheap ones. This thing works so well and really keeps the bubbles bubbling. I once forgot a bottle that had this stopper on it for A MONTH in my fridge. When I opened it, it was still drinkable and bubbly. I was shocked. Warning: it will sound like a gunshot when you remove it so be careful lol

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.

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

Behåller bubblorna och smaken i flaskan. Riktig kvalitet som fungerar

Hervorragend, dichtet 1 a ab , selbst wenn nur noch wenig in der Flasche drin ist und man öffnet die Buddel erneut nach einer Weile, dann zischt's richtig. Habe mir gleich noch einen bestellt.

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.
