This 1972 Chambertin Clos de Beze is from D. Robert Groffier and was properly stored. Many of the reds from Burgundy in 1972 were rather green, harsh, and acid in youth. In years such as 1972 and 1957 such wines are too harsh for early drinking with pleasure, and many never come around. Some last a long time, but develop a somewhat paint-like bouquet. However a few become decent, but not great, drinking if kept long enough.
This wine is still medium scarlet with some age showing around the rim. It has now smoothed enough to be decent drinking, although the acid is on the high side making the wine better with food than alone. It has a decent bouquet of dark fruit with some beet and slightly earthy character. I did not notice any off paint-like character, but there is a bit more vegetable character than I like. It is now a quite decent wine for drinking with food.
I would not encourage anyone to take the chance of keeping Burgundy from green years in the hopes that it will come around, because most such wines will not reward the long wait. However if you come across such an older wine at a low price, it may be worth a try if you can taste a sample before buying it.
