Mix salt, carrots, celery, pinot grigio, bay leaves, and peppercorns in 2 quarts of water and bring to a simmer. Add the shrimp and just bring back to a boil. Once the water boils, cook for 60 seconds. Remove the shrimp immediately and lay out on a cookie sheet to cool to room temperature. Refrigerate until chilled, about 1 hour. Peel shrimp just before serving and serve chilled.
