Anyone bagging grapes on the vine?

I have a backyard grape vine and this year at least 25% of grapes are damaged by what I believe is "grape berry moth." I have been reading about bagging grape clusters (e.g. tying paper bags around the ripening clusters) as a method of protecting them from pests. Has anyone tried this? Do you use special bags or just regular lunch bags?

In past years I have tried Neem as an organic pest control method, but did not really see much improvement, plus it was a lot of extra work. I would like some non-spray solution to get better (e.g. non-maggoty!) grapes.

I haven't had pest problems, but I have had furry thieves. When I'm organized, I cover my "starting to be ripe" grapes with bags I made out of old sheer curtain material with a drawstring to tighten it. You need a *lot* of them to do much good if you want a crop.

Organza bags work well and can be reused.  Need the larger 8x12 inch ones.

Bagging fruits is common practice around here in Kochi, Japan. There are bags made specifically for it. The material and size seems to depend on the particular fruit. There are bags made particularly for grapes for instance.
