English: What do you have for red/white wine?
French: Qu'est-ce que vous avez comme vin rouge/blanc?
During meal or drink service, a passenger may ask you about your wine selection. They might prefer either red or white, and ask you what kind of red wine or what kind of white wine you carry. Here's one way they may ask you this question.
Vous avez=You have
Qu'est-ce que vous avez comme vin rouge?
What do you have for red wine?
Qu'est-ce que vous avez comme vin blanc?
What do you have for white wine?
Notice in French, we literally say "What do you have *as* red/white wine?"
