Botrytis or grey rot

A delicate balance. The former can produce sublime sweet wines. It feeds on the water in the grapes, thereby concentrating the berries in sugars and aromas. The latter irremediably condemns the berries, which from then on begin to smell of vinegar. Not always easy to tell one from the other by eye, but there is no mistaking them on the nose or palate.
