If you are an attorney who likes to drink wine and you want to keep track of what you like, or if you just want help picking out an impressive bottle during your next dinner with a client, there are quite a few wine-related apps for the iPhone. Ben Boychuk reviews five of them for Macworld, and his review is here. His favorite for keeping track of wines that you like is Wine Pad 2, and his favorite for wine reviews and recommendations is Drync Wine. I have also seem some good reviews of the similar Cor.kz Wine Info. Both Drync Wine and Cor.kz are iPhone apps that require an Internet connection to access an online database -- which for Drync Wine has over 800,000 wines, and for Cor.kz has over 530,000 wines.
Another option is to use the Hello Vino web app. Just use Safari on your iPhone to go to http://i.hellovino.com and get some help picking out a wine. This one is limited and aimed at novices, but it is free.
I haven't spent enough time with these to make my own recommendation, but if you have any favorites, please let me know.
