Petrus is not actually a 'chateau' per se, although it is often referred to as such.

Critic tasting note: (2016 vintage) "Graphite, cedar, mushrooms and dark fruit on the nose. The palate shows ethereal elegance, with fruit concentration that dissipates gracefully, while the tannins integrate seamlessly toward the finish. Exceptional. Open, with an elegant, subdued structure. Drink now or hold. 10 Years On retrospective." - James Suckling
