A New Screw-cap Study

[Roy Hersh]

My problem with these studies us that 2 years is nowhere near sufficient to judge the aging capability of closures. What wine is considered aged at 2 years old?

We need someone to commit to a 20-yr study if they want real results.

Reading the article, it looks like this could throw up some interesting data even in two years.

As for longer tests - i was under the impression that some producers were already running long-term tests (20+years) on cork, plastic, stelvin and others (including crimped beer-style crowns)

I think they answered that one for you Glenn - Sauvignon Blanc is aged at 2 years
Personally I hate the stuff and whether it is aged under stelvin or cork will do nothing to change that.

I'm certain there were a lot of trials done in my part of the world on this but I don't know that there was a definitive outcome. We are getting to the stage now where we have significant amounts of reisling at 12 or 13 years old under stelvin. I've not had the opportunity to try any quite that old myself but I've tried a few 2005s this year that were developing wonderfully. I think that over 80% of production here ends up under screwcap now.
