Over at Louisville Juice, Tom Johnson raised some questions about a campaign by Whole Foods to recycle cork closures in his Environmentalism That Feels Good, But Doesn’t Really Accomplish Much post. In the comments, Patrick Spencer of Cork ReHarvest makes some excellent points about why it really does accomplish much. I came away with more information about the environmental impact of using cork. I recommend you go read it.
The discussion also made me think more about the use of metal screw-cap closures. They are produced with aluminum and perhaps aren’t as environmentally friendly as I had previously thought. I invite someone with expertise to comment on the environmental pros and cons of using screw-caps. It is still true that to consistently achieve the aromas and flavors that the winemaker intended to have you experience in a bottle, the screw-cap closure seems to be the best choice.
What are your thoughts?
Update: The Wine Curmudgeon reports on the recent improvements in cork closures.
