With the wine preservation system, you can pour your favourite wines without pulling the cork. With this system you can preserve still wines for weeks, months or even years. Please note that a colder cork will take longer to reseal (approx. 1 minute). Leave chilled bottles upright after pouring to allow more time for re-corking. Coravin Timeless systems also work with agglomerated cork, multi-piece cork and twin-top cork. Be careful when using bottles with wax seals. A thin wax coating will not affect its use - it is malleable enough not to damage the needle or hinder your access to the wine. A thick slice of wax under the film, which is most common with vintage ports, can seriously damage the needle. Coravin Timeless systems do not work with glass closures. This type of closure causes permanent damage to the Coravin needle.
