The 1976 Corton-Charlemagne Grand Cru is showing brilliantly, unwinding in the glass with notions of lemon curd, saffron, iodine, smoke and beeswax, followed by a medium to full-bodied, satiny and fleshy palate with a taut core of fruit and a racy spine of acidity. Concentrated and intense, it's only as it approaches room temperature that this remarkably youthful white Burgundy begins to show all its potential. Less evolved than the 1973 and 1979, it's a terrific bottle from this brilliant decade chez Bonneau du Martray.
