How much white wine do you use cooking mussels?

When cooking mussels, typically about 1 to 1.5 cups of white wine is used for every 2 to 3 pounds of mussels. The wine adds flavor and helps steam the mussels open. You can adjust the amount based on personal preference or the specific recipe, but this range is a good guideline. Always choose a good quality wine that you enjoy drinking, as the flavor will enhance the dish.
