Very tasty party nibbly dish.
Instead of Gouda, you may wish to use Edam or Monterey Jack, or even Brie! This recipe is easily doubled and tripled. It's great for party nibblies, but make sure you allow lots of time -- or organize helping hands -- for the time required to assemble a large enough quantity. Or be clever and make them a day ahead, and store in fridge covered with plastic wrap. Note: the grapes do need to be seedless. If you have a few extra chopped grapes left over, use them to garnish the stack of wedges when you put them out. Kids love to make this -- but not all may eat them owing to the "bits" inside.
