Fruit spoilage and ochratoxin a production by Aspergillus carbonarius in the berries of different grape cultivars

► Rot and OTA production were not observed for undamaged inoculated grapes. ► Incubation at 4 °C completely inhibited the rot and OTA production in grapes. ► Incubation at 30 °C promoted rot and OTA production more than 25 °C. ► Reducing sugar content decreased and then increased in damage inoculated grapes. ► Rot was fastest in Thompson seedless, slow in Kyoho and lowest in Red Earth.
