Took a couple of bottles of Benetiere Côte Rôtie 2010 Cordeloux to Chez Bruce last night. One bottle was sensational and singing, the other was just muted, less expressive and slightly astringent compared to the other. I assumed it was a slight but undetectable TCA problem but one of our party( a wine importer) said he thought it a problem with the phenols in the cork and called it corklin and not directly related to TCA. Any thoughts, scientific basis? New one on me!
