I have tasted more than my share of Haut Brion and La Mission, and have come to share the opinion of a now absent friend that due to the common ownership (both under the Dillons since 1983), the latter wine, which in many vintages surpassed Haut Brion, was intentionally delegated to second place.
"Robert Parker has awarded it more 100 point scores than any other wine in the Medoc, equalling Petrus in achieving 12 perfect 100 point scores."
