If a label says Margaux then the grapes all come from Margaux, if it says Medoc then the grapes are from the Medoc part (which Margaux is a part of), and if it says Bordeaux, then you get the drift...
Thought I'd jump in again, what do you mean exactly? (Booth) Are you referring to Bordeaux and the slightly more strict Bordeaux Superior? I've attached an appellation map to try and be helpful, and the right does have "general space" for these two groups, but rest assured if a wine is from Pomerol, St. Emilion (or their satellites), Fronsac, etc. and meets all of the appellation's respective requirements the appellation's name will be on the bottle (to charge more...), you won't need to know each and every chateau.
Blending using (better) grapes from all over is a way some of my favorite Bourgogne domaines make a better quality "Bourgogne" than other domaine's village level wines (which you can't label your wine by a village if your grapes came from all over). In Bourgogne these domaine's also either own vines all over the place or buy through a negotiator, but I'm getting a bit off topic now...
