"The cork is under assault. Wineries are using plastic stoppers, and (yes, it’s true) screw-top caps on top-notch vino. The plastic lobby says cork’s no good, that it taints the wine. The cork lobby says it’s being slandered, that conscientious consumers will choose cork because it’s also environmentally-correct. No one’s quite ready to embrace the screw-top, but it’s coming. Is this really a conversation about what’s best for the wine lover, or what’s best for business?"
