I would usually agree, as I enjoy most CdPs with 10-15+ years on them. But I’ve had this wine a few times, and they have all been quite advanced. This bottle in fact was the most youthful of the 3 or 4 times I’ve tasted it, and even this one I found to be more advanced than I would expect from a 5 year old CdP.
There are a few other local winos that have said the same thing about this wine, so maybe there was a shipment issue here with the entire lot.
