In my last sighted review of the 2016 Cos d’Estournel, I wrote: "I suspect it will close down for a period in its youth." Perhaps it is already beginning to shut down, because though this wine was deeply impressive, it fell just a notch short of ethereal previous bottles, despite its "pixelated black fruit" on the nose and "sublime balance" on the palate. I tasted the wine twice thereafter, though this time with a 4-6 hour decant, and this revealed the Cos d`Estournel that has amazed since I first tasted it out of barrel. 100 points
