Coravin Capsules Argon (6-pack),. A wine-preservation system is intended to pour from a compatible bottle while limiting the oxygen introduced to the remaining wine. Use only the capsules, needles, closures, and bottle types approved for the specific model, and inspect every component before pressurizing or pouring. Clean the needle and wine path according to the manufacturer's sequence after use; dried wine or improper storage can interfere with flow and sealing. The system is especially useful for comparative tasting and by-the-glass service, where several bottles may be sampled without committing to opening each one conventionally.

Store the device depressurized and protected, and replace worn consumable parts before they compromise the seal or the quality of the pour. Careful handling and storage will help preserve the working surfaces and finish between uses. Its stated function should guide where it is placed, how it is handled, and how it is cared for between uses. For personal use or gifting, its maker, format, origin, and intended service provide the most useful points of comparison.
