At the end of any wine tasting, the big question is “so which one won?” Sure, a few of you liked this one, and that other one had 97 points from a big magazine, but can you say which one your group liked with confidence? Now, you can! With WineTaster, your rankings are taken with rigorous statistical methods to prove, once and for all, who won and who lost. Initially developed by notable oenophiles professors from the Princeton University economics department for their own wine group, WineTaster is a simple, easy, and fun way to take your wine tastings to a new level. Not only can you see if a wine really was head and shoulders above the rest, you can also get statistics about the degree of correlation between tasters, to help understand who’s palates are most compatible. You can comment on your tastings and save them to iCloud, and share your notes with your fellow tasters when you’re all done.
