One of the (decidedly minor) challenges of the Coravin wine preservation system is that it doesn’t work with screw-capped wines. Because the system involves a thin needle piercing the cork, allowing the cork to re-seal after it’s withdrawn, it just isn’t possible to use it on a metal screwcap.
Now, says Coravin, the problem is solved.
Coravin Screw Caps, which are available in two sizes to ensure a proper fit on any bottle, combine self-sealing silicone with the same premium cap liner, to create a tight seal that protects wine for up to 3 months. To use, simply unscrew a bottle’s cap and quickly replace it with a Coravin Cap. Then, access and pour as you normally would with any Coravin Preservation Opener (like all Coravin accessories, the Screw Cap is compatible with all Coravin models). Store the remaining wine and once the bottle is empty, remove the Screw Cap and reuse – it withstands 50 punctures!
The Screw Caps come in two different sizes, and they’ll be arriving on the market later this year.
I tried them out and quickly found that my biggest issue was finding a screw-capped wine that I would bother using with the Coravin. Sure, there are luxe screwcap bottlings, but these are rare. Most screw-capped wines today are cheap bottlings that I’m not interested in preserving for three months. Few last more than a night around these parts.
Using the system really couldn’t be simpler. Remove the original screwcap and replace it with the Coravin model. Then drive the needle through. It even pierces the silicone more easily than cork.
Results: I used the system on a bottle of sauvignon blanc and found that after a week, the wine remaining in the preserved bottle was just as fresh as when I’d originally poured it. In other words: It works just as well as the original Coravin. That said, I can’t imagine using the screwcaps very often, but should the need arise, it’ll be handy to have a couple around.
