When I was in wine country of Hungary I was surprised. ( not knowing much about wine) the grapes are just awful to eat. I mean terrible. And the condition of some of the grape that they were making wine with. Yikes. You would never eat them. They looked like they were grapes that were found on the ground. The wine was fantastic though.
