My advice is to keep your Durand handy when you want to make absolutely positive that the cork comes out clean. For my 50th birthday, we had a serious line-up, and The Durand helped us open every one without an issue. Spectacular performance, spectacular wines. The most venerable of them: Saint-Julien 1920, Château Gruaud Larose, Saint-Julien 1924, Château Léoville-Las Cases, Pauillac 1924, Château Pontet Canet.
