Bring first 5 ingredients to a boil in a medium saucepan. Reduce heat, and simmer, stirring occasionally, 10 to 12 minutes or until reduced by half. Remove and discard anise and bay leaf.
Process reduced wine mixture, vinegar, and next 3 ingredients in a blender until smooth. Turn blender on high, and gradually add oil in a slow, steady stream. Serve dressing with mixed salad greens or grilled fish. Store in the refrigerator.
