Description

Botrytis, causal agent Botrytis cinerea, is a fungal disease of grapevines that is commonly referred to as Botrytis bunch rot or grey mould. Botrytis is most prevalent where warm, wet conditions are frequent, but symptoms can occur in cool, wet weather and high humidity. All grape varieties are susceptible. Varieties most at risk are those with berries that are thin-skinned and/or have tight bunches.

Some white wine grape varieties infected with Botrytis may decay, in certain conditions to produce noble rot . Wine produced from these infected bunches produce unique aromatic characters with high residual sugar and are usually sold as dessert wines.
