The foundations of Seppelt were laid in 1851 when Joseph Seppelt established Seppeltsfield in the Barossa Valley. On the other side of the country, young Frenchman Jean Pierre Trouette followed the gold rush to Victoria and formed a partnership with Anne Marie Blampied and her brother, Emile. They established the first vines in the Grampians region with the historic St Peters vineyard in 1863. By 1867, their estate had grown to 50,000 vines.
