I always use a wine that is drinkable. It truly makes a difference. The first time I made this recipe I used 3/4 cup of wine and it was still very good. If you like a lot of gravy feel free to use this amount of wine. I use a generous amount of salt in my recipes. If you are concerned about salt, start with using half the amount in the recipe and then taste the dish - add more salt to satisfy your taste bud, up to the recommended amount.
