The Pewsey Vale property was first planted to Riesling by Joseph Gilbert in 1847. The site was later purchased by well known grazier Geoff Angas Parsons, who in 1961 invited his friend Wyndham Hill Smith to jointly develop the historic vineyard. They believed the site could produce delicate Rieslings in the Germanic style. High in the Eden Valley's low fertility, grey and sandy loam soils, a prolonged ripening late into the cool autumn season develops recognizably consistent flavour profiles, today known as classic Pewsey Vale.

Over a century and a half of wines have flowed from the superlative Pewsey Vale vineyard. From a clone planted in the Eden Valley during the 1800s, traceable to some of the original vine cuttings brought into Australia by James Busby. Any new plantings are propagated from the original vines. Pewsey Vale is not an easy vineyard to manage. Lean and hungry soils which limit the vigour of the vines, the high altitude and the vineyard's specific microclimate have necessitated the adoption of specialised viticultural management. The property itself is an idyll of gently undulating hills, fifty hectares of which are under vine, nestled close to Pewsey Vale Peak, just west of Eden Valley town centre.
