Best way to learn about wine is to drink it. It's not magic with weird incantations that must be said over the wine. Wine tastings are great learning experiences but wine will taste different with different foods (and will taste different with food than without). I like sauvignon blancs but not from certain regions. And I like merlots but not from some countries. Different people like different things but its easy to let yourself get intimidated. If you like it, drink it, even if it's Boone's Farm. Read a bit, list a winery, drink lots of wine.
