The last three Bordeaux vintages?

As Richard represents us in Bordeaux this week (explained here), tasting his way through the 2013s, we present this look at the last three relatively challenging vintages there as expressed by one of the better crus bourgeois, Ch d'Agassac. The descriptions immediately below are theirs, the tasting notes at the bottom are mine. See also yesterday's link to Professor Denis Dubourdieu's 10-page report.

To us [at Ch d'Agassac], whether a vintage's reputation is considered mediocre or great, the most important thing is to make good wines our clients enjoy.
