The magic of Botrytis Cinerea

Botrytis Cinerea: curse or blessing

The fungus is present on the undeveloped fruit immediately after flowering and appears on the grapes as soon as they start to ripen. Its arrival is unpredictable, which has a significant effect on yield, making each harvest even more precious.

If the weather is damp the fungus develops as grey rot and makes the harvested grapes unusable. Any such clusters are cut off and disposed of.

If damp mornings in the vineyard are followed by hot days the fungus develops as noble rot. It destroys the grape’s skin making it permeable to water, thereby leading to greater concentration. The grape becomes raisined and its flesh highly concentrated in sugar and aromas of candied fruit that are characteristic of Sauternes wines.
