Coravin Pure™ Capsules power all Coravin Wine Preservation Systems. They are filled with pure Argon gas that pressurizes the bottle to allow wine to flow through the Needle, then blankets the remaining wine once the System is removed. 

• Compatible with all consumer Coravin Systems
• Each Capsule will allow to pour up to fifteen 5-ounce (150ml) glasses of wine
• Argon gas does not affect the quality and taste of the wine
• The capsules are made of recycled steel
