Wikeeps Capsules: The Smart Coravin Replacement
Simply screw a Wikeeps capsule into any Coravin wine preservation system designed for 27 ml Professional cartridges.
Since 21 ml and 27 ml capsules share the same threaded design, they’re fully compatible. Just transfer the black plastic adapter from your used Coravin capsule to the new Wikeeps unit for an instant perfect seal.
Why Wikeeps makes the best Coravin-compatible refill
Each stainless steel capsule contains a professional blend of 80% food-grade argon and 20% CO₂ from Linde. Laboratory tests show this gas mixture effectively preserves wine’s aroma and taste for over 30 days, proving it’s a reliable wine preservation system.
A single capsule typically lasts for about 18 glasses – equivalent to three bottles. After use, recycle the steel container and always press the handle to check for any remaining gas flow before recycling or replacing.

Perfect compatibility between Wikeeps and Coravin
Standardized sizes for seamless fit
Wikeeps offers identical dimensions to Coravin capsules – the 21 ml size matches Coravin Model Three, while the 27 ml version fits Professional models including Pivot systems.
With identical threading, the only difference between brands is the removable adapter. Transfer this small plastic piece to ensure a complete seal and full compatibility.
Easy 3-step adapter transfer
- Confirm your Coravin capsule is empty (no hissing sound means it’s depleted)
- Remove the black plastic adapter from the used capsule
- Screw it onto your new Wikeeps capsule, insert, and continue preserving wine
Always check threads and seals before installation to prevent leaks, and avoid overtightening either the adapter or threaded connection.
Made in the EU, these 27 ml (8.5g) argon+CO₂ refills are fully recyclable and directly replace Coravin Professional capsules. Each typically preserves 3-5 bottles. Store unopened units upright and use within six months, or by the expiration date on the package.

Superior gas blend for modern winemaking
Coravin systems traditionally use pure argon gas for serving wine, as this inert gas creates a protective barrier against oxidation. When you pour wine using this method, the argon gas capsule forms an invisible shield that preserves flavor with each serving.
Wikeeps has developed an innovative approach to wine preservation, protected by a French patent. While maintaining argon as the base (80%), we’ve added 20% CO₂ – a gas blend supplied by Linde Gas that replicates the professional standards used by top wineries for tank inerting and preserving wine during barrel aging.
You might wonder about adding CO₂ to the flow. The blend makes perfect sense when you consider that many natural wines now undergo fermentation in a CO₂-rich environment. This 20% addition matches what’s naturally present in the wine, resulting in less harshness than pure argon while better protecting delicate white and rosé wines from oxidation – all without ever removing the cork.
French laboratory tests prove the effectiveness: Wines preserved with Wikeeps Argon+CO₂ gas cartridges maintain their sensory qualities (aroma, texture, and color) for over 30 days. The secret lies in how this dual-gas system maintains optimal pressure inside the bottle while preventing oxygen contact.
Step-by-step: replacing your Coravin capsule
- Remove the empty capsule: First, depressurize by holding the trigger until the hissing stops, then carefully unscrew the capsule holder.
- Transfer the black adapter: Take the black plastic adapter from your original Coravin capsule (visual guide available here if needed).
- Install the Wikeeps capsule: Screw the adapter onto your new Wikeeps refill by hand, insert it into your device, and tighten the holder completely to ensure a perfect seal.
- Test and serve: Give the trigger a gentle press to check the wine flow – your system is now ready for seamless wine access without ever pulling the cork.
Common questions about Coravin-compatible capsules
Are Wikeeps capsules truly compatible with all Coravin models?
Wikeeps gas capsules are designed to work specifically with Coravin devices that use the 27 ml Professional format, including the Pivot system and other still-wine preservation setups. For proper compatibility, remember to transfer the original black plastic adapter from your used capsule to the new one. This ensures a tight seal and secure fit every time.
How many bottles can I serve with one capsule?
On average, a single capsule allows for pouring three to five standard 750 ml bottles – approximately 18-30 glasses of wine. The actual number depends on factors like how much pressure you apply, your pouring speed, and overall serving style. Gentle, controlled trigger presses help conserve gas and extend cartridge life.
How do I know when a capsule is empty?
When your Coravin stops dispensing wine and you don’t hear the characteristic hiss of argon gas (with the gun detached), your capsule is depleted. Before replacing it, always release any remaining gas by pressing the trigger to fully vent the system. This safety step prevents accidental pressure release during replacement.
Can I switch bottles mid-capsule without risk?
Absolutely, as long as you confirm there’s sufficient gas remaining. Check by listening for the gas flow or doing a quick test pour. While it’s best to match capsule type to wine style, any Wikeeps still-wine gas capsules will temporarily protect your next bottle in a pinch.
What about sparkling wines?
Standard argon capsules should never be used for sparkling wine with Coravin. Instead, opt for Wikeeps Bubbl® CO 2/N 2 capsules specifically made for the Coravin Sparkling system. These special refills maintain bottle pressure and preserve bubbles for about a week after opening.
Each 27 ml Bubbl capsule contains an 80% CO 2/20% N 2 food-grade mixture exclusively compatible with Sparkling systems. One capsule typically treats seven 750 ml bottles, and the durable steel canisters remain fresh for up to five years when stored properly.

How should I store and dispose of cartridges?
Store unused capsules upright in cool, dry conditions and heed the expiration date. After use, recycle the empty steel containers with regular metal waste – never attempt to puncture, refill, or burn them.
Are the gases safe for wine and the environment?
Food-grade argon and CO2 are naturally sourced from the air, meaning they’re completely safe for both the environment and human health when used properly. These same winemaking gases are trusted by leading vineyards to protect their barrels and are at the heart of modern wine access technology, ensuring every bottle maintains its premium quality.
Why professionals choose Wikeeps refills
Our argon capsules create an efficient wine preservation system that offers significant cost savings without compromising on quality. The carefully balanced Argon + CO2 mixture preserves a wine’s aromas, taste, and texture for over a month, and these cartridges work flawlessly as direct replacements for Coravin Professional systems.
Manufactured in the EU using Linde’s high-quality winemaking gases, each cartridge is designed for effortless recycling when empty. Whether you’re serving wine casually at home or operating a professional establishment, Wikeeps delivers consistent performance, easy refills, and excellent long-term value for wine preservation.
We recommend testing a single cartridge first—try it on an everyday bottle to check the fit, ensure a proper seal, and evaluate how well it preserves the wine’s characteristics with your specific wine access setup. This quick test will confirm perfect compatibility with your Coravin device and guarantee optimal protection across multiple argon cartridge refills.
