This guide covers everything needed to choose the right compatible Coravin replacement capsules, from gas composition and adapter transfer to pour yield and cost savings, so every bottle stays at its best from opening to the final glass.
Choosing Coravin capsules for wine preservation
Not all Coravin capsules perform alike. Gas purity, cartridge size and system compatibility separate the genuine capsules from the compatible alternatives.
Genuine argon options for Coravin
Coravin pure argon capsules remain designed for still-wine preservation across the Timeless and Pivot ranges. These capsules power Coravin Timeless and Pivot devices by pressurising the bottle through a hollow needle. The needle pierces the cork without removing material, and the cork reseals naturally once it is withdrawn. Argon gas capsules contain 99.99% ultra-pure argon, an inert gas that blankets the remaining wine and limits contact with oxygen.
- Gas purity: Genuine Coravin pure argon capsules use 99.99% food-grade argon, produced in Austria to standards that exceed conventional food-grade requirements.
- Pour capacity: One capsule yields approximately 15 standard 150 ml glasses with Timeless systems, rising to around 20 with an optimised Coravin Pivot pouring technique.
- System fit: Each capsule screws directly into the Coravin capsule housing through a standardised A-type thread. It is compatible with Timeless, Pivot, Professional and selected Limited Edition models.
Genuine Coravin replacement capsules are sold individually or in multipacks. Coravin’s patented cap and seal technology helps prevent gas leakage between uses, while short, controlled presses on the Coravin trigger limit argon consumption and extend yield per cartridge. Forceful or prolonged presses reduce the number of pours available from a single capsule.
Compatible Coravin capsule alternatives
Three trusted brands produce Coravin capsule alternatives using the A-type screw-fit threading found across Coravin A-series models: Wikeeps, Ourgon and Winaro. Wikeeps cartridges are available in 21 ml (6.5 g) and 27 ml (8.5 g) steel formats. Both are accepted by the original Coravin black adapter and regular Pivot devices.

CO₂ cartridges for sparkling wine
Argon capsules power Coravin systems intended for still wines, whereas the Coravin Sparkling system follows a different principle. A dedicated co2 capsule replaces the pressure lost when sparkling wine is poured, maintaining carbonation rather than simply protecting the wine with an inert gas. Argon and CO₂ cartridges are not interchangeable; fitting the wrong type risks equipment damage and poorer wine quality.
A single Coravin Sparkling CO₂ capsule can cover up to seven standard 750 ml bottles of sparkling wine, keeping the remaining fizz fresh for at least four weeks. By contrast, a coravin argon capsule for still wine yields roughly 15 to 22 glasses, depending on the model and pouring technique. The wine style, not simply the device model, should therefore determine the format.
Argon cartridge fitting and performance
The Wikeeps argon gas capsule uses an oenological blend of 80% argon and 20% CO₂, sourced from Linde, which specialises in food-grade wine gases. The CO₂ content has two functions: it helps release residual oxygen and awaken a wine’s bouquet, while moderating the slight astringency that pure argon can introduce during extended preservation. Consult the specifications for the Wikeeps argon gas capsules to verify compatibility with the Professional system before ordering.
Independent French laboratory testing confirms that the Wikeeps system maintains wine quality for more than 30 days when the cartridge and device are used correctly. A 27 ml Wikeeps cartridge delivers approximately 18 standard pours, with the potential to reach 22 under optimal conditions, comparable to the upper range of genuine Coravin performance. The 27 ml cartridge therefore holds enough gas for roughly 18 pours, or up to 22 with careful technique.
| Criterion | Genuine Coravin argon capsule | Wikeeps compatible (27 ml) | Coravin Sparkling CO₂ |
| Gas composition | 100% argon, 99.99% purity | 80% argon / 20% CO₂, Linde food-grade | Pure CO₂ |
| Compatible system | Timeless, Pivot, Professional | Timeless, Pivot, Professional, Limited Edition | Coravin Sparkling only |
| Cartridge size | Standard A-series | 21 ml or 27 ml, A-type thread | Dedicated sparkling format |
| Pour yield | 15–22 glasses | 18–22 glasses per 27 ml cartridge | Up to 7 × 750 ml bottles |
| Preservation duration | Extended, varies by use | Over 30 days (lab-verified) | At least 4 weeks |
| Needle compatibility | All Coravin needle models | All Coravin needle models | Sparkling needle only |

For clarity, the same product family may be described as an argon capsule, an argon gas capsule or a coravin argon capsule, depending on the system and search context. The capsules power Coravin Timeless devices, while argon capsules power Coravin Pivot and other compatible still-wine systems.
Frequently asked questions
How do you transfer the black adapter from an empty Coravin cartridge to a compatible replacement?
The black plastic cap on an empty Coravin cartridge contains an O-ring, which creates the airtight seal on which the system relies. Then twist the cap counterclockwise and hand-tighten it onto the new Wikeeps cartridge until firm resistance is felt.
The adapter can be reused indefinitely. A replacement O-ring costs under £2 at hardware shops if the original wears out.
How do you know when a Coravin capsule is empty, and can you switch cartridges mid-bottle?
The clearest indication is that wine stops rising in the glass despite correct pouring technique. To check, detach the device from the bottle and press the Coravin trigger: a clear hiss indicates that gas remains, while silence confirms that the capsule is spent.
If gas is heard with the needle removed from the cork but not when it is inserted, the needle is probably blocked by cork particles rather than the cartridge being empty. A needle-clearing tool is included with all Coravin systems for this purpose. To replace a cartridge mid-bottle, first confirm the empty Coravin cartridge is fully depressurised by holding the trigger, then unscrew it, fit the replacement and continue service.
What is the difference between a Wikeeps compatible cartridge and a genuine Coravin capsule in terms of gas blend and cost?
Genuine Coravin capsules contain 100% argon at 99.99% purity, whereas Wikeeps cartridges use a proprietary oenological blend of 80% argon and 20% CO₂, sourced from Linde. The CO₂ fraction is not enough to carbonate still wine. Instead, it helps displace residual oxygen and softens the slight dryness that pure argon can introduce during extended preservation, a distinction that matters particularly with delicate varieties such as Pinot Noir and with natural wines.
Wikeeps capsules cost up to 40% less per pour than official refills. A 24-packs drops below the price of 18 original cartridges at standard retail, and orders over 30 capsules ship free within Europe.
