Preheat the oven to 400°F. Toss beef bones, onion, carrot and celery in olive oil. Roast for 1 hour, turning half way.
Meanwhile, place the stew meat, celery base, garlic, turnip, parsley, bay leaves, salt, pepper, thyme and rosemary in a large stock pot. Add the roasted vegetables and beef bones to the pot, although with any remaining liquid. Pour the red wine into the hot roasting pan to deglaze, loosening all the browned bits. Pour the wine and browned bits into the stock pot.
Add enough water to cover ingredients, plus two inches.
Simmer on low heat for 4-7 hours, the longer the better. About 2 hours after cooking, pull out the bones and using a potato nail or the end of a meat thermometer, scoop the marrow out and return to the stock along with the bones. The mixture might not be the deep brown color you are used to, after the mixture sits and fats separate from the broth, it will be less cloudy and more brown.
The liquid will have reduced by half, if not more. Using a slotted spoon, scoop out all solid ingredients. Line a colander or large sieve with a triple layer of cheesecloth and place over a large bowl, Dutch oven or casserole dish. Strain liquid through the cheese cloth. Discard solids. Cover and place liquid into the refrigerator.
After liquid has chilled, all of the fat will rise to the top and solidify. Now it can easily be spooned off the top leaving only deep, rich and flavorful beef stock. Now use your beef stock for something fabulous!

*My grocer sells beef bones frozen in large hunks. Apparently not a lot of people in my area make their own stock. The problem is that frozen bones rarely have a lot of meat on them, so I compensate by adding extra stew meat. If your bones are super meaty you can omit the stew meat.
