What is an appellation?
In America, an appellation is a geographical-based term used to identify where grapes for wine are grown. In some countries an appellation has rules that govern what type of grapes are grown there, how they are bottled and how the wines are named. Here the rules basically say that to have the name of an appellation on your wine bottle at least 85% of the grapes for that wine must be from the specified appellation.
