The Durand® removes old and fragile corks whole and undamaged. Instructions for use are printed on the inside of the reusable wrapper that encloses the cork presentation box of the Durand.
 
The Durand® is a fully patented, two part device that enables the user to successfully remove older and fragile wine corks whole and intact.   The Durand was invented by wine collector Mark Taylor who had struggled with challenging corks when opening older fine wines.   He founded Wining Taylors, LLC (based in Atlanta, Georgia, USA) to manufacture and market The Durand in 2007. The Durand is named for Yves Durand, a world-renowned sommelier, and a personal friend and mentor.
 
Using The Durand for older, fragile or compromised corks eliminates the unwanted outcomes of broken corks, corks pushed into bottles or corks partially removed leaving pieces floating in the wine. The Durand removes the cork whole and contained.
