Add stock, salt, and wine to a large measuring cup or bowl.
Add Butter to a large skillet placed on medium burner. Melt.
Once melted, add finely chopped shallots. Cook for 2-3 minutes, until shallots are tender and opaque.
Press garlic into shallot mixture. Heat for about a minute, until it becomes fragrant.
Add Arborio Rice to the skillet. Stir and heat for about a minute.
Add 1/2 cup of broth mixture to the rice. Stir until combined, and continue stirring occasionally until the liquid has been absorbed.
Once liquid has been absorbed, continue adding 1/2 cup liquid at a time, stirring after each addition until it has absorbed. Stir often, as the more you stir, the creamier your final product will be.
With the last 1/2 cup addition, add your reserved, chopped nettles.
Once liquid has been mostly absorbed, but the mixture is still a bit "soupy", add the Parmesan. Stir to combine, and until liquid is mostly absorbed. Check for seasoning and adjust salt as needed.
Remove to plates. Grate a bit more Parmesan over top. Enjoy!
