Hundreds of quality wines have switched to screwcaps as it is simply better for the wine. This now includes wines selling for over USD 100 per bottle. One winery even charges a premium for screwcap over cork (yes, it is a higher price if you want the same wine in a screwcap -- admittedly they use a very fancy screw cap, but it is a USD 15 extra for this bottling). But this is not new; in NZ 90% of wine is bottled using screwcaps. Even in the US it has been around for over a decade -- the most famous is Plumpjack bottling 10,000 cases in 1997 including their Reserve Cab which cost USD 160 when released ... in a screwcap. After 10 years of aging the verdict is in (aged better in screwcap than in cork).
