The place where I purchase grapes (Corrado's Market in NJ) always has boxes of grapes they call "mixed black." Has anyone ever tried these? They never say what kind of grapes they are. Is this the stuff they can't sell any other way, or does someone attempt to make a blend of grapes that's better balanced than the individual varieties?
I will be buying grapes this weekend, and I'm wondering if anyone has tried them or knows anything about them.
