Plump, sweet grapes filled with soft goat cheese and crunchy pistachio nuts are a perfect, bite-size hors d'oeuvre.
Place the nuts in a small bowl. Dip the rim of each grape into the nuts.
Take 1 level teaspoon of the goat cheese and place it in the center of a small square of the cheesecloth. Twist the cheesecloth slightly, pinching the cheese into a ball. Unwrap the cheese but leave it on the cheesecloth. Holding the ball with the cheesecloth, transfer it to a grape cup and pull away the cheesecloth. Continue until all the grapes are filled, using a fresh square of cheesecloth or rinsing the same piece.
The goat cheese may be piped into each grape individually, but the cheesecloth method gives it the appearance of artisan-made cheese.
