Good to see you posting. Interestingly, I tasted the 2003 Cos d'Estournel a few weeks ago. I thought I had already entered a tasting note earlier this year and went back to read it, to respond to your post. I found I had not added a recent note and so this was a good reminder.

All wine appreciation is personal taste. You might not like the wine. But based on my recent tasting note, and numerous previous tasting notes for 2003 Cos d'Estournel, I imagine your bottle was heat damaged. What did the cork look like?
