Every time you buy a bottle of wine sealed with a natural cork stopper, you’re helping to sustain one of the world’s most biodiverse forests and protect an extraordinary ecosystem.
While it might seem counterintuitive, the best way to ensure that there is no shortage of cork is to use more cork. That is because the greater the demand for cork, the greater the economic incentive to protect the cork oak forests for future generations.
The 6.6 million acres of cork oak forests in the Mediterranean Basin not only serve as a refuge for endangered species, they also help reduce greenhouse emissions. It seems like a small thing, but every cork stopper represents a carbon offset of 113.5 grams. Looked at differently, the 6.6 million acres of Mediterranean cork oaks capture approximately 14.4 million metric tons of carbon dioxide.
Not only do cork oak forests provide a significant carbon offset, but cork stoppers are 100 percent natural and recyclable; they are truly the gift that keeps on giving.
“We have recycled more than 47 million cork stoppers and have planted more than 8,000 cork oaks,” says Matt Hughes, brand manager at ReCORK, North America’s largest cork recycling initiative. “Our recycled corks are used to replace petroleum-based materials in consumer products and to extend the useful life of wine corks.”
Contrary to popular opinion, cork oaks are never harmed or cut down during the harvesting process. Highly skilled professionals use axes to safely and carefully strip the bark. On average, 90 to 130 pounds of bark are harvested from each cork oak. Each tree can produce enough cork for 4,000 to 6,000 stoppers.
Cork’s unique attributes make it a highly versatile material. Because cork is composed of a honeycomb of microscopic cells, it is very light, easy to compress yet strong, impermeable to liquids and gases, adaptable to temperature and pressure, an insulator against moisture and noise, and resistant to fire. When it comes to preserving wine, cork allows just the right amount of oxygen to interact with the liquid, making it the perfect material to allow wine to age properly. And when it comes to the wine experience, no artificial stopper can come close to reproducing the iconic “pop” when the cork is removed.
