Is it obvious now? I've written earlier about what a cork can tell you - the most important information it provides is cellaring condition. The young wine on the left...cork shows no seeping, perfectly even stain on the end. The one on the right - showing more wear and tear. Cork is mishapen, drying out, with a deep stain in the center. Still drew out quite cleanly, in one piece. A miracle, considering it was about 25 years old.
