CORAVIN Argon Wine Preservation Capsules 6-Pack Silver — Pure 100% Medical-Grade, Leak-Free Fit

Coravin Pure argon capsules are replacement gas cartridges that supply ultra-pure argon to Coravin wine preservation systems so you can pour without removing the cork.

Designed specifically for Coravin devices, these six medical-grade argon capsules maintain wine freshness by gently pressurizing the bottle during pours. Each capsule is manufactured and inspected under strict standards to ensure purity and compatibility with Coravin systems. Lightweight and easy to store, the box contains six capsules so you can refill your device several times before restocking.

How do these capsules keep wine from oxidizing?

When you insert the Coravin needle and pressurize the bottle, argon replaces the small volume of wine poured, forming an inert blanket over the remaining liquid and slowing oxygen contact. Coravin Pure argon is selected because it’s heavier than air and does not react with wine, helping preserve aroma and flavor during short- to medium-term storage.

• 100% ultra-pure, medical-grade argon 5.0 for inert protection
• Designed to introduce gas without disturbing the bottle’s internal pressure balance
• Works with compatible Coravin systems for consistent pours

What quality checks ensure these capsules won’t affect taste?

Each capsule is produced in a controlled, medical-standard filling environment and undergoes a two-stage deep cleaning procedure to remove contaminants. Post-manufacturing, capsules face a multi-point sensory inspection to confirm there are no off-odors or residues that could influence wine character.

• Two-stage cleaning removes particulate or volatile contaminants
• Filled and sealed in a medical-grade facility for traceability
• Multi-point inspection prevents compromised cartridges from shipping

How do I know these capsules will fit my Coravin device?

Coravin Pure capsules use patented cap and seal technology engineered to mate precisely with Coravin systems’ safety mechanisms. The fit prevents leaks and ensures the device dispenses gas in a controlled way for a smooth, reliable pour every time.

• Patented cap and seal for leak-free connection
• Compatible with Coravin models that accept Pure capsules
• Simple swap-in installation—no special tools required

How many pours can I expect from one capsule?

Pours per capsule vary with pour size and wine type, but each cartridge provides multiple servings for typical glass pours. The six-pack gives you a convenient supply that suits occasional hosts, restaurants, or enthusiasts who like to taste a variety of bottles without opening them fully.

• Multiple standard pours per capsule (depends on pour volume)
• Six capsules per box for several refills
• Compact packaging for easy storage or travel with select Coravin models

Who is this for: Enthusiasts, home entertainers, sommeliers, and hospitality professionals who use Coravin preservation systems and want a dependable source of ultra-pure argon. If you regularly taste single glasses from multiple bottles or run a wine program that demands consistent preservation without opening every bottle, this six-pack offers a ready, quality-controlled supply that integrates seamlessly with compatible Coravin devices.
