In a heavy non-reactive stock pot or Dutch oven, place the onions, carrots, leek, thyme, and rosemary, garlic, juniper berries, whole cloves, bay leaves, salt, sugar, and peppercorns. Add the red wine, Rosemary Balsamic Vinegar, and water. Heat this marinade mixture on high to bring to a boil, then reduce the heat, cover, and simmer for 10 minutes. Turn off the heat and let the mixture cool.
