At tasting, the nose of this wine reveals many aromas, especially notes of graphite, crushed stone, blackberry and blackcurrant. On the palate, the Chateau Cos d'Estournel 2012 is rather full-bodied, structured, but with well-integrated tannins and a long finish. Its great aging potential makes it possible to keep this wine until 2022 or even later.
