Bob Oatley established Rosemount Estate in 1969 after a career in the coffee industry where he was awarded the British Empire Medal for his services in Papua New Guinea. Bob Oatley instilled at Rosemount Estate a mentality learned in the coffee industry; that a quality product will always be sought out and appreciated. Bob Oatley's wish to establish a reputation for fine wine production was satisfied early and has led Rosemount Estate to establish a wide variety of vineyard sites around Australia that take advantage of the varied soil types and regional climates. In 1992 he was awarded the Graham Gregory Trophy for 'Significant contribution to the Wine Industry of New South Wales.'

The Rosemount Estate crest reflects the Upper Hunter Valley setting of the Rosemount Estate and the passions of the founding Oatley family. The horse silhouette on the top left denotes the many stud farms of the Upper Hunter Valley and the Oatley family’s long association with thoroughbred horse racing. The adjacent rose represents the beautiful rose gardens that lead up to the cellar door at the Rosemount Estate Denman Vineyard. The bunch of grapes below signifies the long, and successful history of viticulture at Rosemount Estate.
