How Coravin argon capsules preserve wine freshness
These systems create a protective, non-reactive argon layer that prevents oxygen from spoiling your wine. Understanding the gas mix, seal quality, and cartridge capacity helps maximize each capsule’s lifespan while ensuring perfect pours every time.
What gas blend do argon cartridges for Coravin contain
Coravin works with 100% Argon gas while french manufacturer Wikeeps works with a specific blend known for being less astringent for wine : their capsule contain about 80% argon mixed with 20% CO₂ – a food-safe blend from reputable gas suppliers. The argon forms an inert barrier while the CO₂ maintains optimal pressure and can subtly enhance certain wine aromas without affecting taste.
- Pure argon option: Coravin Pure™ capsules use over 99.9% argon at 2,600 PSI for complete protection.
- Blended benefits: The 80/20 mix offers argon’s preservation plus CO₂’s pressure benefits, especially great for whites and rosés.
- Sparkling wine choice: Special CO₂-rich capsules with nitrogen (for Wikeeps & Bubbl. specific blend) keep bubbly fresh for days by matching bottle pressure.
Since argon is heavier than air, it naturally settles over the wine to form a stable shield. Research from the argon’s protective role shows properly preserved wines maintain quality for 30+ days after opening.
Coravin capsule compatibility across all wine system models
Choosing the right Coravin gas replacement prevents leaks and ensures proper flow. Wikeeps cartridges work with all Coravin Pro systems when using the original’s black plastic cap.
Official Coravin Pure cartridges come in 21ml and 27ml sizes that fit Timeless™, Pivot™, Model Six, Model W, Professional, and Limited Edition systems. They won’t work with Coravin Sparkling™ which needs special CO₂ capsules. For reliable preservation, try high-quality compatible cartridges that maintain steady pressure.
| Capsule Size | Compatible Models | Adapter Required | Service Capacity |
| 21 ml (6.5 g) | Timeless™, Pivot™, Model Six, Model W | Black plastic end cap | ≈15-18 glasses |
| 27 ml (8.5 g) | Professional, Limited Edition | Black plastic end cap | ≈20-22 glasses |
| A65 21ml Retail | Retail Coravin units only | None (integrated) | ≈15-180 glasses |
| PRO 27ml Type | Professional models only | None (integrated) | ≈20-22 glasses |
How long does a Coravin argon capsule last
The 27ml cartridge typically pours about 22 glasses – enough for 3-5 bottles. The 21ml size covers roughly 18 glasses, but actual use depends on pour size and speed.
Tasting pours instead of full servings can make one cartridge last a whole bottle. For consistent performance, check out the advantages of argon capsules that maintain steady pressure to the last drop.
Independent tests and real-world use confirm wine preserved with pure or blended argon stays true to character for over a month.
Safe handling and disposal of Coravin gas replacement cartridges
Store cartridges upright below 149°F away from sunlight until their six-month expiration. Never expose to flames or try to refill used cartridges.
- Empty check: If no hiss or wine comes out when squeezing the trigger, it’s ready to recycle.
- Recycling: Completely empty steel cartridges go with metal recycling – never trash pressurized units.
- Warranty note: Unapproved cartridges may leak, damage your system, and void the warranty.
Damaged cartridges should be used within six months. For guaranteed-safe replacements, try high-quality argon cartridges made to strict EU food and safety standards.
Frequently Asked Questions
How long does a Coravin argon capsule last?
A single 27 ml Coravin argon capsule typically allows you to pour about 18–22 glasses of wine (five-ounce servings), which equals three to five standard 75 cl bottles. This depends on your pouring technique and the pressure applied. The smaller 21 ml cartridge usually provides 15–18 glasses, or approximately three bottles. When used properly, pure argon capsules help preserve the wine’s taste and aroma for over a month after the first pour.
Are all Coravin capsules the same?
No, Coravin capsules differ in size, gas composition, and compatibility. Models like Coravin Timeless, Pivot, Six, and Professional use pure argon (over 99.9%) for still wines, while Sparkling systems rely on CO₂-nitrogen mixes to maintain bottle pressure and bubbles. Third-party options, such as Wikeeps, sometimes blend argon with CO₂ and may require an adapter, but they still let you pour multiple glasses of wine while keeping opened bottles fresh if installed correctly.
How to dispose of Coravin argon gas canisters?
To safely dispose of a used Coravin capsule, first empty it completely by pressing the handle until no more argon escapes. Once depressurized, recycle the steel cartridge with other metal household items—it’s usually accepted like tin cans, but check local guidelines. Never throw away a pressurized bottle in regular trash. Instead, store used canisters upright in a cool place until recycling to ensure safety and adherence to gas disposal rules.
