This dark garnet-colored wine shows considerable amber at the edge. I have always had a tenency to taste this side by side with the 1971, and it has been fascinating how the 1971 was fully mature at a much younger age yet continued to hold onto life without losing any of its seductive fruit and intensity. The 1970 started off life more tannic, backward, massive, but needing considerable time, and it has now hit full stride. It is a profound Petrus, and certainly one of the great Petrus’ of the last half century. The wine has a huge nose of cedar, caramel, vanilla, tobacco, fruitcake, and licorice-infused black cherry jam. It is unctuously textured and very full-bodied, with extraordinary sweetness and glycerin, and a layered, viscous finish. This wine should continue to drink well for at least another 20 years. Anticipated maturity: Now-2025.

I drank this last year with some wine collector friends ­you guessed it: in Hong Kong! It’s a very special bottle I’ve been lucky enough to have tried on a number of occasions, and it never disappoints. The nose shows olives, brown sugar and dark fruit. It’s full and joyous with round tannins and a flavorful finish. Truly sublime, and among the great vintages of this legendary estate such as 1947, 1990, or1998.

The 1970 Petrus here is far superior to the one poured in London a few months earlier. The bouquet is crystalline with a mixture of red and black fruit, hints of thyme, ferrous notes percolating through with time. So much poise and that is translated through to the palate framed by filigree tannins, a perfect line of acidity and black truffle notes towards the elegant finish. This is an outstanding example but be warned that there is bottle variation. Tasted at Epure restaurant in Hong Kong.
