(Decanter) - Coravin screw caps have been made available to Coravin Club members and are expected to go on general sale in the UK from 15 September, the company said this week. A pack of six caps costs £29.95, it said.

It has already launched the screw cap devices in the US this summer.

Coravin said its screw caps can keep wine fresh for up to three months once the original cap seal has been removed and the first needle puncture from the Coravin system is made.

Buyers still need a Coravin system to extract wine, as they would if the bottle was sealed with a cork.

‘A screw cap solution has been a popular request since introducing the original Coravin in 2013,’ said Greg Lambrecht, founder and inventor of Coravin.
