On Palate Press: A New Entry in the “Which Closure is Greener” Debate

My December column at Palate Press, the online wine magazine, is now up. I revisit an issue I covered in late 2011 — the relative environmental impact of natural corks versus screw caps — with new data from Nomacorc, the leading manufacturer of synthetic (plastic) cork-like closures.

Closure for closure (that is, if we ignore the question of waste as a result of wines made undrinkable by the failure of their closures), natural cork still comes out as the most environmentally friendly choice in nearly every respect. A bigger point is that closures are a very small part of the total environmental impact of a wine. (How small? Probably an unanswerable question, unless we’re calculating numbers for a specific wine.) That said, if you’re the kind of person who reuses her plastic wrap, it might be worth remembering that the neck of your wine bottle can contain something made from metal, something made from plastic, or something made from a tree that’s still standing and respiring in a Mediterranean cork forest.
