Add the beef, tomato paste, onions, carrots, garlic, star anise, cinnamon, bay leaves and lemongrass to a large pot.
Pour in the 300ml of red wine and enough water to cover the ingredients.
Bring to a boil, then reduce heat and simmer for 2-3 hours, until the beef is very tender.
Remove the bay leaves, lemongrass and garlic head.
Taste and adjust seasoning with fish sauce, adding a little more red wine if desired.
Serve the beef and broth over rice noodles, topped with the spring onions, herbs, chillies and lime wedges.
