The 1970 Chateau Margaux was born during a weak period for the estate and it has long been an underperforming wine. It's not terrible, but it unquestionably does fall a long way short of what you would expect from a First Growth. It has a one-dimensional nose with rather lifeless tar and cedar scents. The palate is showing a touch of volatility on the entry with charred, dry tannins that lead down towards a foursquare finish, which can best be described as "dull". Tasted June 2015.
