The illustrious Douglas Green. As an Elsenburg graduate and a qualified viticulturalist and winemaker, Douglas Green had a reputation for his very fine palate and astute tasting abilities. In 1916 his service in the Royal Navy placed him in Europe, and after the First World War he lived and worked in the Champagne region of France where he gained valuable experience, and brought the "first bulk sparkling wine fermentation process" to South Africa.
