Thanks to each of you for your advice. I was really hoping to just be able to choose something without asking her preferance, etc. I kind of figured that it would be too difficult though since wine is such a complex subject. I know that whenever we are out, she always drinks red wine...just not sure which type of red. I guess I should have paid more attention. Oh well...I'll see what I can find out from her without giving too much of my plan away.
Thanks once again for all of your suggestions.
