Cork vs. Plastic
Have you noticed how many wine bottles have plastic corks these days? I couldn’t help wondering why. After all, aren’t we meant to be replacing synthetic products with natural ones where possible, to help clean up our planet—not the other way round? Intrigued, I did a little research, and found the wine industry is in the midst of turmoil.
For centuries, in fact for about as long as people can remember, wine has been sealed with cork stoppers. So close is this link that you can’t really think of the one without the other, and indeed, the humble cork is a wondrous thing. Wholly natural, it is flexible and durable, forming an excellent seal to a bottle, yet one that allows itself to be extracted with relative ease. What’s more, it forms the basis of a noble, age-old industry that has become a part of the physical landscape and human fabric of countries like Spain and Portugal.
This industry is also eco-friendly and sustainable, as the cork is harvested by removing the barks of the region’s cork oaks in a seven-year cycle, and the cork stoppers themselves are biodegradable natural products. Why then, is this industry in peril as the market has suddenly become flooded with plastic substitutes? Although plastics manufacturers have clearly put a lot of effort into making their creations look like the real thing, they cannot hide the tactile proof that they’re plastic—and far from beneficial to the environment.
