Landware had an app called "Wine Enthusiast Guide" for $19.99 that was pretty good. Handmark's web site says the app is still available and that it was last updated 3/12/09 but it still carries a 2007 date in the app title. Landware's web site says the app is currently only available for the iphone and the ipod touch.
My wife bought the app for me as a birthday present in 2007 and I just didn't use it enough to make me want to pay to update it. Definitely worth a little research if your interested as it was a pretty good app.
