Michigan and Niagra region wines have been impressing me. California wines, unless pre-2005ish vintage reds are a waste of money due to the long drought there.
German Rieslings are a good bet if she likes sweeter wines, French reds if she prefers dry.
A traditional celebratory wine is Italian Moscato, which is a bubbly white. A higher end bottle of that will run you $30-$40.
I used to be quite the wino, with a 300 or so bottle cellar at my old place, but switched over to bourbons 5-6 years ago so I've been out of the current trends but am glad to help with what I may know.
