cattitude bought some Delaware grapes at the Greenmarket, since they didn't have the Vanessas I'm so fond of. These are similar in being small and a reddish-purple color that gets grapes called "red". The grapes cluster very tightly together.
They're a more intense grape flavor than the Vanessas, which I'm not sure I like, and the skins are tougher. I wonder how they'll taste chilled.
