What kind of grapes were they?

This question really bothers me, and has haunted me perpetually. It’s weird that a taste could have such an impact on me, but it has.

When I was about three my parents owned a fine dining restaurant with a room for catered meals. At one of these catered meals there were very elaborate ice sculptures, on a grand buffet with all sorts of fresh fruit and other eats.

One of the fruits that was given to me from this grand buffet was a grape. It was so pale green, that it sort of looked like it was glowing. It was slightly elongated. The flavor was very mild, and unlike any grape I have ever had since.

I harbor some suspicion(and fear) that my memory has put the flavor of something else onto the picture of a grape. In this case the flavor could not be recovered unless I stumbled upon something with the same taste.

Does anyone know any pale green longish grapes with a mild, melon/kiwiish flavor.

A couple of people have recommended green sicillian grapes to me, but I can’t find anywhere to purchase them outside of sicily.

Is there a place to taste a very wide variety of grapes from around the world, in one place?
