From the back of the box:

When you play Karafe, you become the wine maker. You buy your vineyard; harvest your grapes, bottle your wine and sell it. Just open a few bottles of wine and let the party begin. There are over 500 interesting questions or wine taste tests divided into two category levels, so everyone from the sipper to the connoisseur can compete on a level playing field. By the time you play the game just a few times you will impress all of your friends with your knowledge of wine.
