Approaching Margaux

Approaching Margaux, I crossed through vinyards. The Médoc is known for most prestigious and expensive French red wines. I do prefer an affordable "Côtes de Blaye" from the eastern side of the Gironde, but I I have to admit, I never ever tasted Crus du Médoc (Pauillac, Margaux, Saint-Julien..). I just can´t afford to spend a week´s budget for a bottle of wine.
