I also think you should ask her what kind of wine she likes first. Just ask her if she likes dry or sweet. That may help you make the right choice. Then you stand more of a chance of "hitting it".
Cause , you know, I always let any man who makes the right wine selection "hit it"!
Anyways, my vote is white zinfandel served ice cold. I'm not a real big wine fan but I do like that stuff. Though it's really debatable if it's a wine at all.
