Did You Know?... You Might be Drinking a Wine Blend

When you look at a bottle and see it labeled as Cabernet Sauvignon, you might think that you are getting nothing but the juice of Cabernet Sauvignon in your glass. But every wine growing region has rules for just how much of certain varietal needs to be present before you have to put it on the label or make clear it is a blend. A winemaker adds different grapes to a wine for a variety of reasons, usually to augment the primary grape, and usually in small enough quantities (1-2%) that it doesn't show up on the label.
