Jordan Winery Associate Winemaker Maggie Kruse discusses how wine corks are made. This video shows the cork tree bark–what wine corks are made of– and explains cork harvesting from the forests in Portugal and the quality control steps that are taken to ensure each bottle of Jordan wine has the best closure possible. Learn how cork trees grow before cork is carefully removed without cutting down the tree. Harvest and production footage courtesy of http://www.100percentcork.org.
