About this item Coravin Pure™ Argon Capsules power Coravin Timeless and Pivot™ Wine Preservation Systems. They are filled with pure Argon gas that pressurizes the bottle to allow wine to flow out the spout, then blankets the remaining wine once the System is removed. Argon Capsules are NOT compatible with Coravin Sparkling™ – they are specifically made to be used on still wines. SKU Code: 410028
