Yes, you could buy a single bottle of wine that costs more than your house, but you know what? It's still just going to be a single bottle of wine. Not to mention, that's not five star frozen ravioli you'll be serving it with. So why not save the money and drink something that's just plain ol' respectable?
Look, cheap wine has a bad reputation as a waste of money. But you know what? Not all cheap wine is "cheap wine" if you get what we're saying here. These wines were picked because they taste good, not because we found them behind a gas station in a pile. Save a little money on the libations, your dinner party guests won't ever know.
