The name Caillou refers to pebbles, reflecting the fact that this was once riverbed, when the river Garonne overflowed millions of years ago. The characteristic elegance and finesse of this wine is attributed to its free-draining, gravelly soil and subsoil. Lovely, gentle grassiness and wet-stone minerality, with enough weight to give this real substance. A great example of white Bordeaux wine.
