Feedback for my wine cellar tracking/assistant app

I built cellarbuddy.com based on a conversation I had with my wife a week ago where she wanted a particular type of wine, but we couldn't decide which bottle to open. The app let's you easily upload your wine, track consumption, and get expert help on what to drink. Check it out out and let me know if you'd find it useful and if there's anything that can be done to improve it.
