Combine 1/4 cup wine, 1/4 cup broth, garlic, allspice, and ginger in a shallow dish; add ribs, turning to coat. Cover and chill ribs for 4 to 6 hours, turning occasionally.

Remove ribs from marinade, reserving marinade. Sprinkle ribs with salt and pepper; dredge in flour.

Cook ribs, in batches, in hot oil in a Dutch oven over medium-high heat 15 minutes or until browned. Remove ribs, and set aside.

Reduce heat to medium; add carrot, onion, and celery, and sauté 7 minutes or until browned. Add tomato paste; cook, stirring constantly, 3 minutes.

Return ribs to pan. Stir in reserved marinade and remaining 2 cups wine and 2 cups broth; bring mixture to a boil, and tightly cover.

Bake at 300° for 3 hours. Remove ribs.

Skim fat from sauce and discard; simmer sauce for 12 to 15 minutes or until reduced by half. Serve with ribs over roasted potatoes. Garnish, if desired.
