The above picture might not do it clear justice, but when I pulled that little plug of tree bark from a bottle of 2004 Pernand-Vergelesses 1er Cru En Caradeux "Clos de la Croix de Pierre" from Domaine des Héritiers Louis Jadot last night, I was greeted not just by an unmistakable stench but also by a very muddy looking scene, as if the biz end of the cork had been dipped in a slurry of wine and gray modeling clay.
I've no hard science to back up my observation, just many years of first-hand experience. While there have been plenty of corked wines where the stopper looked normal, I don't think I can remember an instance where the cork had this particular muddy appearance and wasn't also tainted.
Your thoughts on the matter would be most welcome.
