Did a seminar at the austrian wine academy. Not cheap (150€), but you learn a lot (in 2 days). You also drink a lot (tasted 25 wines, you had to write a comment about each). You have to do an exam at the second day (its a lot harder after “tasting” all that wine). But if you are sitting and drinking a bottle with your friends and you can tell a few things, its priceless.
