What's the Best Wine Stopper for the Environment?

I just finished reading an interesting (and informative) article on about.com that takes a close look at what type of wine stopper is best for the environment. The question is a huge issue, considering the millions of bottles of wine that are manufactured and stoppered each year. From Australia, to France to California, every bottle and type of wine is different, but they do have one thing in common - the bottle gets topped with either a cork, a screw cap, or a variety of plastic stopper.

So which one of the above varieties makes the most sense, environmentally speaking? According to this article, cork is absolutely the way to go. The author discusses that unlike plastic or metal screw caps, cork is a sustainable resource with economic benefits. If you're interested in reading the entire article, I've linked to it below.

To Cork, Or Not to Cork?
