RSVP

I am putting an email out for my customers to reply with RED or WHITE (wine give away) I was thinking RSVP would be the right way to do this but I'm now seeing Yes No and Maybe might be the only featured responses, is this correct? Maybe an Event is what I need to create? How do I get both the option of the response of RED or WHITE and more importantly, I need to know that Joe says RED and Sally says WHITE because otherwise I won't know which wine to drop off to them, how can I receive this very specific information? New user here, thanks
