How argon capsules evolved from cellar practice to consumer wine preservation
For generations, winemakers have protected their barrels with argon gas in the cellar, using this noble gas to prevent oxidation before bottling. Wikeeps transformed this professional technique into an easy-to-use system with their cartridge set of argon capsules. When you open a bottle and pour, these capsules release a protective cloud of inert gas that forms an invisible barrier against air and oxygen. This innovation maintains the wine’s delicate aromas, rich flavors, and freshness for weeks, bringing professional-grade preservation right to your home or restaurant.

Why we combine argon with CO₂ in our wine capsules
While pure argon’s density makes it ideal for shielding wine from air, our research with Linde Gas revealed that blending in 20% CO2 creates an even better solution. This carefully balanced mixture, contained in our wine capsules (marketed as Wikeeps capsules), not only removes oxygen more effectively but also preserves the wine’s texture, preventing the slight astringency that can occur with 100% argon. This same gaz oenologique formula is what top châteaux trust to protect their finest vintages – now available for your home preservation needs.
Food-grade purity certified by Linde
Each batch of our gaz oenologique meets rigorous 99.99% purity standards, with full documentation provided for quality assurance. This laboratory-tested inert gas ensures what you pour from your bottle tastes exactly as the winemaker intended, whether you’re enjoying a vibrant Sauvignon Blanc or a complex Pinot Noir.
Compatibility with Coravin and other preservation systems
Our high-quality argon capsules—available in 21 ml (6.5 g) and 27 ml (8.5 g) sizes—feature the same 200-bar threading as Coravin cartridges, ensuring a perfect seal with Professional, Sparkling, Preservino, and Wiserve dispensers. To use Wikeeps cartridges with your device, simply transfer the black plastic end-cap from your original Coravin cartridge to our refill. The preservation system works flawlessly—each trigger release delivers the same amount of protective gas, so you’ll never need to adjust your device.
Seamless adapter transfer for instant use
If the cap sticks due to adhesive residue, a quick soak in acetone or nail polish remover will loosen it. Once attached to our cartridge, it functions just like the original part, allowing you to effortlessly switch between Wikeeps capsules without disrupting service.

Performance metrics: how many glasses and bottles per capsule
A single 27 ml cartridge preserves approximately 22 glasses—equivalent to four 750ml bottles—while maintaining optimal freshness with an inert gas barrier. In actual bar usage, each set typically protects between three to five bottles, depending on pouring style and pressure application. Our scientifically formulated 80% argon and 20% CO₂ blend has been independently tested in France, proving it preserves wine taste for over 30 days.
Discover how Wikeeps capsules extend your wine’s freshness, ensuring every glass tastes as perfect as the first pour.
Sparkling wine preservation with dedicated CO₂ capsules
Our specialized Bubbl. capsules for sparkling wine use a precise CO₂/nitrogen blend to maintain proper bottle pressure and prevent oxidation, offering unparalleled sparkling wine preservation. This innovative solution keeps Champagne and other sparkling wines beautifully effervescent for up to seven days after opening—perfect for establishments serving premium bubbly by the glass.
Cost efficiency and bulk options for hospitality venues
When compared to OEM Coravin cartridges, Wikeeps capsules offer savings of up to 40%, with additional discounts available for bulk purchases. Restaurants and bars can maximize their savings by opting for the large 80-unit box—this economic choice reduces both administration time and per-pour costs, freeing up resources to enhance staff development or expand their wine selection.
- Trial set: Perfect for initial evaluation, this compact 5-capsule pack accommodates low-volume testing.
- Retail pack: Designed with enthusiasts in mind, the 12-cartridge box meets home preservation needs.
- Hospitality pack: The ideal 80-unit set for commercial venues handling higher bottle turnover.
Shipping costs and threshold benefits
We’ve streamlined global logistics with DHL—orders under 30 cartridges ship for a flat €22 fee, while larger shipments (up to 80 loose cartridges) cost just €22.88. Most European clients quickly qualify for free shipping, simplifying cost planning for hospitality businesses.
Operational workflow and best practices for professionals
The system works just like standard Coravin devices: simply connect the cartridge, position the device over your bottle, then pull the trigger to pour and reseal. Always ensure complete capsule insertion—any gap allows gas leakage, indicated when the characteristic argon hiss cuts off unexpectedly.
Identifying an empty capsule and safe replacement
A capsule needs replacing when wine flow stops or the argon hiss ceases. Between bottle changes, fully depress the handle to flush out residual air and argon—this crucial step maintains flavor purity across different wines.
Environmental benefits and recycling guidelines
Our stainless steel cartridges belong in your regular metal recycling, alongside aluminum cans. Since argon is extracted from atmospheric air during standard gas production, the environmental footprint remains minimal. Learn more about Wikeeps’sustainable approach—all capsules meet stringent European production standards.
Waste reduction through prolonged bottle life
Our preservation system extends opened bottle freshness for weeks, dramatically reducing waste while increasing profitability from by-the-glass programs. Establishments enjoy fewer spoiled bottles and more efficient service—a win for both operations and sustainability.
Product range: still and sparkling wine solutions
We offer two specialty product lines. Our “All Wines” Wikeeps capsules combine 80% argon with 20% CO₂ to preserve all types of wine – reds, whites and rosés. For bubbly lovers, we provide Bubbl. gas capsules containing pure CO₂ specifically designed for sparkling wine preservation. Each cartridge undergoes strict leak testing before shipping and features a handy QR code for quick staff training. Discover how argon enhances supplement stability that shields delicate wine aromas from harmful oxygen exposure.
Pure argon variants for specific preferences
For situations requiring total neutrality, our pure argon gas capsules offer complete oxygen displacement without any added CO₂. These versatile capsules work seamlessly with both Coravin and Wikeeps dispensers, giving wine professionals the flexibility to match the perfect preservation method to each bottle.
Why sommeliers stock Wikeeps capsules as backup
Wine experts routinely keep extra Wikeeps cartridges on hand to maintain service quality during busy events. When a Coravin capsule runs empty, staff can simply transfer the adapter to a Wikeeps refill – ensuring uninterrupted service and happy customers. This universal compatibility works across all Coravin models, streamlining inventory while preventing those inconvenient mid-shift stockouts.
