I’m rather fond of sub-$10 bottles of wine. and with that comes a lot of the new screwcaps. I know a fair number of folks who just don’t accept screwcaps. But here is an interseting quote from Rober Parker on that.
Corks will come out
I believe wines bottled with corks will be in the minority by 2015. The cork industry has not invested in techniques that will prevent "corked" wines afflicted with the musty, moldy, wet-basement smell that ruins up to 15 percent of all wine bottles. The consequences of this laissez-faire attitude will be dramatic. More and more state-of-the-art wineries are moving to screw caps for wines that need to be consumed within 3 to 4 years of the vintage (about 95 percent of the world’s wines). Look for this trend to accelerate. Stelvin, the screw cap of choice, will become the standard for the majority of the world’s wines. The one exception will be great wines meant to age for 20 to 30 years that will still be primarily cork finished—although even the makers of these wines may experience consumer backlash if the cork industry does not solve the problem of defective corks. Synthetic corks, by the way, are not the solution. They do not work and can’t compete with the Stelvin screw caps.
