Preheat oven to 325 degrees Fahrenheit.
Prepare the red wine braising liquid by simmering wine, balsamic vinegar, demi-glace or beef stock, and tomato paste in a saucepan.
Season brisket with salt and pepper, then sear in an oven-proof pot until browned. Remove brisket and saut� bacon, carrots, and celery.
Return brisket to the pot, pour in the red wine liquid, add bay leaves, onions, potatoes, and thyme. Cover and braise in the oven for 2-3 hours, basting periodically.
Meanwhile, cook soaked grits in water until tender, then add whipping cream, butter, and fresh herbs.
Serve the braised brisket over herb grits, garnished with fresh chives.
