Notice several things: the rockiness of the soil (important in giving the wine its almost stony flavor and in forcing the vines to work hard, reducing output and increasing quality), the lack of irrigation (verboten in most French AOC regions), and the lack of an elaborate trellising system like you'd see in California. The latter was most astonishing to me, I think--every one of the individual vines is separately trained up its own wood pole, without the elaborate training and pruning mechanisms I'm used to seeing in Napa.
