Wash your grapes and put them in a large mixing bowl. Mix in the shredded carrots, sliced celery and raisins.
In a medium mixing bowl, beat the sour cream, cream cheese, and sugar together until well mixed. Add your vanilla extract, and almond extract or amaretto liquer and mix well.
Combine the dressing and the salad and mix until everything is well coated. Cover and chill until you are ready to serve.
