BOTRYTIS CINEREA AND DAMAGED GRAPES

The violent and in some cases too frequent rains occurred at the end of summer have favoured the onset of many plant diseases both for the vegetation and the bunch. In some cases, the high frequency of precipitation has favored the onset of numerous plant diseases affecting both the vegetation and the grape cluster. Among these, the most feared is definitely the Botrytis cinerea, commonly called grey mould.

Although the suggestion to limit the damage related to the rottenness of the bunch is always to work well starting from the vineyard, a season like the one under way also tests the best agronomic and defence techniques of the vineyard.

The oenological damage caused by Botrytis cinerea

The worst damage caused by the infection of Botrytis cinerea in grapes is linked to the production of a particularly stable and very soluble oxidasic enzyme, the laccase, increasing the risk of oxidation and browning in musts and wines. However, the grey mould does not exhaust its “bad jokes” here: the oxidative damage is compounded by the production of polysaccharides (ß-glucans) making it difficult to clarify and filter wines and molecules that inhibit alcoholic fermentation like botryticines.

Presence of Botrytis on bunches also favours the establishment of other socalled opportunistic fungi, like some species of the genus Penicillum, responsible for the production of a compound, geosmin, giving unpleasant odours of soil and fungus in wines. The grapes affected by Botritys finally often have deficiencies of nitrogenous substances and vitamins and a greater presence of contaminating yeasts and bacteria.

Good practices for preventing and facing Botrytis cinerea

Selection in the vineyard: before or at the time of the harvest it is always a good prevention weapon.
Protection of grapes and musts from enzymatic oxidation and the development of unwanted microorganisms.
Identification of Botrytis cinerea DNA with ICGENE: AEB's innovative equipment allows for the timely assessment of the presence of this microorganism both in grapes upon receipt and directly in the field. The ICGENE method is so versatile that it can also be used on must and finished wine.
Facilitation of the establishment of the desired microflora to limit the production of undesirable compounds and allow the consumption of gluconic acid.
Guarantee of maximum cleanliness by promoting rapid clarification of musts with the use of enzyme complexes effective on pectins and glucans.
