What type of dry white wine do you use to cook with? Where do you find it in the

[somebodyslife]

store? I'm going way overboard with Martha Stewart' goose recipe. It call for 1/2 cup of dry white wine for gravy. I've never cooked with wine before and I know there's somebody that knows how. Please help, It's my first Thanksgiving without my mom and my sisters fiance. I want to do it right. I've never cooked for her before. Many thanks!
