Combine coconut milk, lime juice, white wine, curry paste, garlic, fish sauce, and sugar in a large pot. Stir to dissolve sugar and curry paste; bring to a boil. Let mixture boil for 2 minutes, then add mussels. Cover and cook, stirring occasionally, until mussels are opened, 5 to 8 minutes.
Remove the pot from heat and discard any unopened mussels. Pour mussels and liquid into a serving dish and toss with cilantro.
