Bottles closed with natural cork are best, because they will reseal after accessing with the Coravin System. Please keep in mind that a colder cork will take longer to reseal.
While a synthetic cork closure will not damage your Coravin Needle the closure will not reseal, and thus permit oxidation after some time. If you access a bottle with a synthetic closure, store it upright to ensure that it does not leak.
Use the Coravin Screw Cap accessory to pour from bottles with Screw Caps. Glass closures are not suitable for use with the Coravin System, as they will cause permanent damage to the Coravin Needle.
Do not use with Champagne or sparkling wines.
