Rotting grapes

i grow white grapes in a north facing veranda with a perspex roof which lets in light and gives protection.  I usually have a good crop and have had wine made from them.  This year i have a good crop but they are just rotting on the vine with some type of white fungus.  Any ideas what i should do to prevent this happening next year?

    Irregular watering can cause grapes to split, then they rot. Also they need adequate ventilation, letting as much air around them as possible.

  • Yes, good ventilation and regular watering, which can be difficult if we have a dry hot summer, and you are away for a while. Remember the roots may spread out a way.
