Sugar Cane corks!

Yes, oak corks are a renewable resource, but they can't be recycled. And what it requires doing to the trees is awful-looking. Enter the sugar cane cork--a cork that is made from sugar cane fiber that remains after the juice is extracted to make brown sugar. The cork is too perfect-looking for consumers, so the manufacturer stamps a "cork pattern" of little lines and dots on the sugar cane cork, to make it look right. This is a novel closure, and worth following.
