Coravin Pure Argon Capsules: The Argon Wine Preserver Behind Every Pour

Why Argon Is the Ultimate Wine Preserver

Argon is a noble, inert gas. It’s tasteless, odorless, and non-reactive. Because it’s heavier than air, argon sits on the wine’s surface and forms a protective layer that prevents oxidation without changing aroma or flavor. 

Coravin wine-by-the-glass systems are precision tools that create an inert argon blanket over the remaining wine. That blanket blocks oxygen, which is wine conservation’s biggest enemy. In short: you pour, enjoy, and the bottle stays as fresh as the first glass over time. 

It is the top choice if you want to preserve the true character, aroma and taste of your most precious bottles. This is why professional argon wine preserver systems are trusted by sommeliers and wine pros.

How Coravin’s Argon Gas Wine by-the-Glass System works

First, a precision-engineered needle accesses the bottle without removing the cork.

Wine flows through the needle into your glass. After you’ve poured, Coravin replaces the volume with argon gas. The inert argon forms a wine-preserving blanket.

Lastly, remove the needle and the cork reseals. The remaining wine stays stable.

That simple cycle is why wine argon gas preserver systems are revolutionizing wine service.

Coravin Pure Argon Capsules: What Are they?

Coravin Pure Capsules are prefilled steel capsules of ultra-pure argon gas made specifically for Coravin systems. They pressurize the bottle as you pour and then blanket the remaining wine to prevent oxidation. 

These capsules power Timeless and Pivot systems and are engineered to meet food-safety and performance standards. On the other hand, Coravin Sparkling solutions use CO₂ and a different method to preserve bubbles, so argon capsules are not used for Sparkling.

Each capsule is calibrated to deliver a predictable number of pours, roughly 15 five-ounce pours with Timeless systems and about 20 five-ounce pours with Pivot systems.

That predictability makes planning service and cost per glass simple for restaurants and pros.

Coravin patented Pure Capsules go through a strict purity process to ensure the argon is food-safe and ultra-pure, so nothing in the capsule alters aroma or taste.
