Heh, I built something similar for my partner and myself: https://wine.unobtanium.de/ It's not very sophisticated (as we're not sophisticated wine people), but we've sometimes found ourselves standing in front of the wine rack in the super market (as I said, not sophisticated) wondering which of those we already had tasted and how we liked it.

There's not that much in it because it was put on a bit of a break owing to a broken server a while ago, but it's back up again :)
