In college there are 4 kinds of wine: white, red, pink, bubbles. There's also expensive wine and Barefoot. For the love of God, step away from the Barefoot. Wine that costs under $10 is not a great deal, its yucky.
This guide should help you pick out a great wine for your guests for dinner parties, lunch dates, game nights... whatever.
I am more than happy to give tasting recommendations to anyone traveling to the Napa Valley. Mine and Matt's favorite is Kuleto Estate.
