Bad luck!
It's powdery mildew - my greenhouse grape has it badly this year as well. As it's the third year running, and depite spraying, I'm getting rid of mine :(

thanks for the reply did wonder if this was the thing.
really disappointing 3 gallons of wine for Christmas last year none this year  really sad and I also thought i might get rid of the vine and start again. will give it one more chance, have removed all fruit and foliage for bonfire. cut it down by half and will spray the greenhouse with jeyes fluid should get rid of ants as well.
it is about 15 years old. so do they have a life span
thanks again
Dave

Nothing to do with the vine or how old it is but everything to do with the fact that grape vines do not like humid conditions. If you get enough air through the greenhouse then it may do better next year.
