Add the beans to a large bowl and cover with water. Let soak overnight.
Add the turkey wings to a large pot and cover with water. Add a pinch of salt, the whole onion, and 3 whole cloves of garlic. Bring to a boil, then reduce to a low simmer. Simmer for 3-4 hours, or until meat is tender enough to pull from the bone. Take the meat off of the bones, shred, then add back to the broth. Remove the onion and garlic.
Add the soaked beans to the broth, along with 3 cloves of chopped garlic and the thyme.
Simmer for 1 hour, or until beans are tender.
Bring a separate pot of water to the boil. Add the nettles in batches and cook for 1 minute.
Wring the water out, then add them to the beans along with the pepper and wine/vinegar.
Cook for 5 more minutes.
Taste for seasoning and add more salt if necessary. Transfer the brothy beans into bowls and top with a good glug of olive oil before serving. Enjoy!
