If you sip wine then you are more than familiar with all the enclosures that are used to finish off a bottle. One of the most interesting is the “Helix”. It combines the convenience of a screw cap with the flexibility and porousness of cork. Made of cork, it has a bulbous, mushroom-like cap with an elongated cork that has internal threads on it that match up to extended threads in the mouth of a bottle. It simply screws out of the bottle opening like a screw cap and does not require a corkscrew for the job. A real benefit is that you can screw the cork back into the bottle if you don’t finish it and the treads match up perfectly. Producers claim it makes an airtight seal that will keep the wine fresh.
