The word terroir, which may be translated, though inadequately, by some such phrase as "native soil" is actually a congeries of facts and ideas comprising the whole range of natural conditions (climate, geology, soil, drainage, landform, environment) plus human factors (technical skill, choice of tools and methods, economic conditions, and, above all, tradition based on a 2000-year history of wine-making).
