Sève (cork)

Sève, or cork, is the tough, insulating outer layer found mainly on the bark of cork oak trees. Composed mainly of dead cells, cork provides a protective barrier against environmental hazards, moisture loss, and pests. It’s highly elastic, durable, and water-resistant, making it ideal for products like bottle stoppers, flooring, and insulation. Harvested sustainably without harming the tree, cork is a renewable resource that regenerates after each harvest, contributing to environmental conservation. Its unique cellular structure allows it to expand and compress, maintaining its protective qualities over time.
