From Thaddeus O. Cooper:
Wine Cellar lets you track the wines that you drink, so you can remember what wines you like -- and those you didn't. You can share your thoughts about wine with friends and family through email or your .Mac account -- and best of all you can have all your wine information with you for that next trip to the wine store by exporting them to your iPod. Wine Cellar makes it easy! And best of all you can try Wine Cellar before you buy it.
