Based on this tasting, the 1970 Pichon-Lalande appears to be losing its fruit and is in decline. The color revealed considerable rust and amber. The wine exhibited some vegetal, tobacco, cedary, blackcurrant scents, but on the palate the sweet fruit in the attack quickly dissipated to reveal acidity, tannin, and alcohol, as well as a tough finish. I have had better examples, but this wine has been fully mature for many years. It may be fading more quickly than I would have thought.
