KLOVEO Champagne Stopper Black - Patented WAF Seal - Made in Italy - Prosecco, Sparkling Wine, Cava

Preserve the fizz with a proven Italian design

The KLOVEO Champagne Stopper Black is built around a patented WAF seal and proudly manufactured in Italy. It employs a self-tightening mechanism that expands as pressure builds, aiming to keep CO2 in the liquid and bubbles lively down to the last pour. The stainless steel clip provides a secure hold without being part of the sealing action, and the unit uses BPA- and Phthalate-free materials for peace of mind.

How it works

• The self-tightening seal expands with bottle pressure, tightening the fit automatically for a bubble-friendly seal.
• The design claims to retain fizz through the remainder of the bottle, helping bubbles stay vibrant longer.
• The clip is a safety feature and does not participate in the sealing mechanism, making it easy to release for quick pour or reseal.
• Constructed from stainless steel and food-grade plastic, avoiding common contaminants in lightweight alternatives.

Versatility, compatibility, and build

• Fits standard 750 ml necks, including Prosecco and Cava; also compatible with many other sparkling bottle formats.
• Italian invention and manufacturing bring together craftsmanship with practical, user-friendly design.
• Lay your bottle down or stand it upright—the seal works in either orientation and helps prevent leaks.

How to use

To seal, press the cap; the seal does the rest. Lock with the stainless steel clip for safety, then chill the bottle to maximize fizz. When you’re ready to pour, release the clip and reseal as needed.

Care and usage notes

Clean with mild soap after use and avoid excessive heat. While some users report extended fizz in practice, always reseal promptly to maintain carbonation and enjoy fresh-tizzed sparkling wines.
