Place the beef in a 13 by 9-inch glass baking dish. Pour the wine over the meat and marinate in the refrigerator for 1 1/2 hours. Turn the meat over and marinate for another 1 1/2 hours.

Remove the meat from the wine and pat dry with paper towels. Reserve the wine.

In a large Dutch oven, heat 3 tablespoons of the oil over medium-high heat. Season the meat on all sides with salt and pepper. Using tongs, place the meat in the pan and brown on all sides, about 2 minutes each side. Remove the meat and add the remaining oil. Add the pancetta and cook, stirring frequently for 2 minutes. Add the carrots, celery, garlic, olives, green beans, potatoes, rosemary, and sage. Cook for 3 minutes. Pour the reserved wine, tomatoes, and beef broth into the pan, scraping up the brown bits that cling to the bottom of the pan with a wooden spoon. Return the meat to the pan and bring the liquid to a boil. Cover the pan and simmer for 3 to 3 1/2 hours or until the meat is very tender.

Remove the meat and the rosemary sprigs from the stew. Place the meat on a cutting board and cut into quarters. Using 2 forks, shred the meat into bite-size pieces. Add the shredded meat to the stew and cook until warmed through, about 5 minutes.
