In 1847 Joseph Gilbert planted a single acre of vines, establishing Eden Valley's pioneer sites and one of Australia's first high altitude, cool climate vineyards. Gilbert trialled many different grape varieties at Pewsey Vale, later distributing cuttings to aspiring growers in surrounding areas. Pewsey Vale eventually fell into disuse until 1961, when the estate's proprietor Geoffrey Angas Parsons, paid a visit to his good friend Wyndham Hill Smith at Yalumba with a proposal to restore the ancient Pewsey Vale Vineyard. Prima is bottled to enhance the exotic nature of this wine whilst preserving its pure fruit flavours. The naturally lower alcohol of the wine further heightens its refreshing character.
