In the interest of accuracy, I am not suggesting that this was anything other than a subjective study carried out, not by a researcher but a winemaker with a vested interest in promoting screwcaps.

I hope it will not be taken amiss but damned good wine is produced at Kumeu River tho' it'd hard to find here!

Screw caps are fantastic. I hope all wineries convert their bottles to use them.

Salut/Hi Richard Neidich,

Dick, are you deliberately trying to wind people up, or do you believe that?

For the sake of intellectual honesty your two choices are not mutually exclusive :-)

But to be honest, with exception of white...I do not believe in screw caps for Quality Reds based upon personal experience.

Some interesting data on screwcaps:

A Closure trial conducted by the Australian Wine Research Institute, has shown there are no adverse effects the ageing of red wines. HOwever there are differences in the wine, under different closures.

Or for the complete paper:

Thank you.

That was my experience that the two Plumpjack cabs of 1997 did age differently. I liked the cork better than the screwcap.

I'd been on a wine tour through the Kaikoura winery in Canterbury a few weeks ago when in New Zealand on holiday. Something very similar to this had been brought up by one of the people on the tour, with the guide then telling us that screw caps were generally more popular there with whites (particularly Rieslings and Sauvignons) as they preserved the flavours/bouquets more effectively than corks. There was also mention of how the cork's contact with the wine could add other unwanted elements to the taste. The guide did mention of some sort of research that was going on in the area in order to test those theories.
