Cork is an important part of the wine industry. Maybe not as critical as the grape, but hard to think of a bottle without it. Salem-based Cork ReHarvest, an environmental nonprofit, is working to bolster cork’s importance as a manufactured good with a new cork recycling program. The Cork Quality Council estimates 13 billion corks are used worldwide each year, and 1 billion in the U.S. Only one-third are recycled. “It’s a throw-away for most people,” says Cork ReHarvest executive director Patrick Spencer. There is enough used cork currently in the industry to put a cork in every bottle of wine consumed in the U.S. for the next 100 years. Spencer founded Cork ReHarvest in 2008. To create the recycling program, Spencer created partnerships between Cork ReHarvest and wineries, Whole Foods, and Corvallis-based molded fiber manufacturer Western Pulp. Consumers bring corks to collection bins at Whole Foods stores. Trucks take the bins to Whole Foods distribution centers and then they are shipped to Western Pulp. Western Pulp expects to receive approximately 1.35 million recycled corks in 2010. It grinds down the corks and combines them with newspaper to make wine-shipping boxes. It’s not clear whether the recycling program will financially impact the wine industry. Cork becomes contaminated once a wine bottle is opened, and cannot be reused to cork another, even if it is recycled. Spencer says recycled cork has a number of uses, including in flooring, shoes and packaging. Winemakers hope the recycling program helps reverse a trend of using plastic corks or screw caps as closures. Cork has come under attack because it can ruin a bottle of wine with “cork taint.” In response, says Susan Sokol Blosser, founder of Sokol Blosser Winery, “there’s been a concerted effort to develop other closures.” Even though plastic corks and screw caps are cheaper than corks, winemakers readily use corks because they are renewable, sustainable and create jobs for people living in the Mediterranean area where cork trees grow. “Cork is one of the few renewable resources that we have available to us in the wine industry,” Sokol Blosser says.

Comments
The quality of natural cork was suspect up until several years ago (and can still be amongst those note using high quality cork). But as the cork industry faced massive loss of market share to alternative closures that rely either on petrolium based products or bauxite mining (for aluminum production) they got their act together very quickly.
I will grant that failure rates were unacceptably high (nearing 10%) as recently as five years ago. Now with improvements to how cork is being harvested, stored, transported, sanitized, and processed the failure rate is down to nearly 1%. A rate I will accept to do what is right by the environment, support this carbon-sink industry, keep thousands of multi-generatio nal workers in employed, and maintaining the tradition of a natural closure for our naturally made products.
Thank you as well, to Alison and our friends and colleagues at Sokol-Blosser for helping to spread the facts about wine closures and participating in the dialogue.
Wine can be aged in screwcap (refer to the Riesling trials of the AWRI from the 1970's that are still going today), it has less variability between bottles and most importantly, it is a guarantee to the customer that there will be the wine in the bottle that the winemaker intended. On top of that, the screwcap can be recycled. It is aluminium, and like cans, can be used again as a screwcap rather than packaging that will be..... (delaying the inevitable, methinks) thrown away! This would put less pressure on the bauxite mines of this world. All that is needed is a plan (like the one in the article above) to put the recycling in place.
Really, the Portuguese NEVER sent anyone in New Zealand a good cork?
You and everyone who chooses to promote alternative closure usage, never address the environmental issues that the United Nations, World Wildlife Fund,the Rainforest Alliance and the Global Environment Facility have all documented. Aluminum and Plastic are not renewable or sustainably sourced. They infrequently recycled and in recent studies have show to be leaching endocrine disruptor's into the wines they are sealing. Endocrine disruptor's are the leading suspects in colon and breast cancer. The cork forests are a carbon sink and oxygen provider and offer one of the highest levels of forest biodiversity on the planet. Find me any information about the positive environmental benefits of mining for bauxite and turning petrochemicals into plastic and then we can have a rational discussion.
Taint is not even near 1% for those who do good QC on their whole cork program (and those who are willing to pay more than the cheapest amount).
Part of the issue in NZ was the fact that Kiwis wanted (expected) corks cheap and weren't willing to pay for quality (nor QC). So they ended up with what they paid for (poor quality corks and some with taint were sent to NZ or eastern Europe, while those in wine regions who paid for top quality--such as California--rec eived much better cork and much, much lower incidences of taint). And many of those who stuck by cork as a natural, historical, sustainable product also spent a lot more on QC and research (private, not just public) and held cork suppliers' feet to the fire to deliver better quality (which all seem to agree is the case).
The truth is, there is no perfect closure. But cork is getting closer and closer all the time, while screw caps and others are starting to look more and more ridiculous all the time (especially in light of the negative environmental impact they have, as others have highlighted).
Think twice (or more).
