Corks, screwcaps and changing attitudes

Ex Wine Spectator editor Jim Gordon asks in a recent report on a symposium on bottle stoppers at Copia in Napa Valley, Has the Anti-Cork Tide Turned?
In view of the recent (if long overdue) advances made by the cork industry, sustainability concerns and the reduction issue as it affects screwcaps, this is a fair and interesting question.
To read how Randall Graham of Bonny Doon, who conducted a funeral for the cork (described here), is going soft on screwcaps and to see who asked leading cork producer Amorim why on earth they hadn’t diversified into alternative stoppers, see this article in the American wine trade publication Wines & Vines.
