A study by viticulturist, Dr John Gladstones, first drew attention to the suitability of the Margaret River region for making wine. Gladstones believed that the soil found in the area, clay subsoil covered by gravelly loam, was ideal for viticulture. He compared the Margaret River climate with that of Bordeaux, indicating that both had an average rainfall of over 1000mms and an absence of temperature extremes, because of the influence of the sea on three sides.
