In a large pot, bring the wine and water to a boil with the bay leaves. Add the mussels, cover and cook over high heat, shaking the pot a few times, until the mussels open, about 5 minutes. Transfer the mussels to a large, rimmed baking sheet to cool. Carefully pour the mussel cooking liquid into a glass measuring cup, stopping before you reach the grit at the bottom; discard the bay leaves. Remove the mussels from their shells.
