24. The quality of grapes
Quantitative QUALITATIVE

Fermentation problems
Loss of color
Increase in volatile acidity
Instability of the wine
Undesiderable flavors and smell
25. The quality of grapes
Another case of global approach:
Botrytis

33. The role of grape moth
yesterday
Grape berry + grape moth larva
=
door for Botrytis
34. The role of grape moth
today
Grape moth = BOTRYTIS2
35. The role of grape moth
What we already knew
Damages from the first
generation of grape
moth can encourage
Botrytis attacks
From damaged berries
can start Botrytis
36. The role of grape moth
New discoveries
Grape moth larvae can carrie
conidia of Botrytis cinerea
Larvae prefer to eat
grapes with Botrytis
