Coravin Capsules 6 Pack

Coravin Capsules 6 Pack is a set of six argon gas cartridges designed to preserve wine through Coravin's needle-based pour system. Each capsule contains 99.99% pure argon gas manufactured in Austria to standards that exceed food-grade requirements. The Coravin system itself has earned recognition including a 2019 Red Dot Award for Product Design and Popular Science's 2013 "Best of What's New" honor.

How It Works & What's Inside

Each Coravin Pure Capsule is filled with food-grade argon, an inert noble gas that is denser than air and completely flavorless. When a capsule is loaded into a compatible Coravin system, the pressurized argon pushes wine through the needle and out of the bottle without removing the cork. Once the needle is withdrawn, residual argon blankets the surface of the remaining wine, forming a protective layer that blocks oxidation by maintaining oxygen levels below 1%. This dual-action mechanism — pressurization during the pour, then blanketing after — is central to Coravin's patented preservation technology. The capsules themselves are manufactured from recycled stainless steel using deep-cleaning processes that surpass standard food-grade protocols.

Preservation Performance

Oxygen Exposure: Independent testing confirms less than 0.5% oxygen exposure per pour, a figure far below the threshold that triggers noticeable oxidation in most wines.

Duration: Because argon is heavier than air, the protective blanket it forms remains stable on the wine's surface for extended periods. Users have reported revisiting the same bottle over the course of nearly two months and finding the flavor profile and acidity virtually unchanged.

Flavor Neutrality: Argon is chemically inert — it does not react with wine in any way. There is no effect on aroma, flavor, tannin structure, or acidity, regardless of how many times the bottle is accessed.

How to Use Coravin Capsules

Insert a capsule into the top of a compatible Coravin Timeless or Pivot device until it clicks into place. The system punctures the capsule's seal automatically when you begin pouring. Each capsule provides enough pressurized argon for roughly two to three standard pours (approximately 5 oz each), depending on pour speed and bottle pressure. Replace the capsule when the gas is depleted — you'll notice a drop in pour pressure. Store unused capsules at room temperature away from direct heat.

Best For

• Wine collectors who want to sample bottles without committing to finishing them
• By-the-glass service at home dinner parties or wine tastings
• Preserving high-value or aged wines that deteriorate quickly once exposed to oxygen
• Restocking a Coravin system that sees regular weekly use

Frequently Asked Questions

What do Coravin Capsules actually do? Each capsule delivers pressurized 99.99% pure argon gas that pushes wine out of the bottle through a needle, then blankets the remaining wine to prevent oxidation — all without removing the cork.

How do Coravin Pure Capsules compare to Wikeeps capsules? Wikeeps argon capsules typically cost 30–40% less than official Coravin capsules and deliver similar argon-based preservation, but Coravin's patented stopper and seal technology is engineered specifically for its own devices, ensuring a consistent gas-tight fit that third-party alternatives may not replicate over time.

Are Coravin Capsules good for long-term wine preservation? Yes — independent testing shows less than 0.5% oxygen exposure per pour, and users have reported preserved wines tasting unchanged after nearly two months of intermittent access from the same bottle.

Where are Coravin Capsules made? Coravin Pure Capsules are manufactured in Austria using deep-cleaning techniques and production standards that exceed food-grade requirements.

Which Coravin systems are these capsules compatible with? The Pure Capsules are compatible with both the Coravin Timeless and Coravin Pivot wine preservation systems.

How many pours does one Coravin capsule provide? A single capsule typically yields two to three 5-ounce pours, though the exact number depends on pour speed, wine viscosity, and the pressure inside the bottle.

Are Coravin Capsules worth the price? Coravin Pure Capsules sit at a premium compared to generic argon cartridges, but the recycled stainless steel construction, guaranteed 99.99% argon purity, and engineered compatibility with Coravin's patented seal system make them the manufacturer-recommended choice for protecting wines of any value.

Why Coravin Pure Capsules?

The core advantage of these capsules is reliability verified at the chemical level: 99.99% argon purity ensures absolute flavor neutrality, and the less-than-0.5% oxygen exposure confirmed through independent testing is a concrete benchmark few preservation systems can match. Argon's density advantage over nitrogen — the gas used in some competing systems — means the protective blanket stays in place longer, often outperforming nitrogen-based alternatives that may fail within days. Each capsule is built from recycled stainless steel, adding a sustainability dimension without compromising the food-safe production standards required for direct contact with consumable beverages. For anyone using a Coravin Timeless or Pivot system, these capsules are the purpose-built consumable that keeps the entire preservation chain performing as designed.
