Add olive oil to a large saucepan over medium-high heat. Add meat ingredients list. Brown the meat. Remove from the heat, drain as necessary.
Using the same pot, add the butter to the pot. Add carrots, celery, onion and pepper. Cook until onions are translucent. Add the garlic and cook for 2 minutes. Add red wine or grape juice. Scrape any bits off the bottom of the pot for flavor. Let everything cook together for 5 minutes.
Add all veggies to a blender or food processor(be careful they are hot!) Blend until mostly smooth.
Add the meat to a large crock pot -- 7 quarts or larger.
Add the vegtable mixture to the crock pot.
Add the remaining sauce ingredients to the crock pot. Stir.
Cook on high for 4-6 hours or low for 7-10 hours. If the sauce is too watery, take the lid off for the last hour of cooking to help it thicken.
