Situated to the west of Blenheim, the Delta Farm was first established in 1846 by Constantine Dillon. The land went through numerous transformations before being purchased in 2000. It had served as a dairy, a sheep farm and because of the splendid elevation of the hills, an airstrip all prior to the creation of Delta’s flagship Pinot Noir vineyard. The shape of the original Delta vineyard is very similar to the symbol for the capital Greek letter 'Delta'; hence the name given to this site on detailed topographic maps of the area.
As the new Dijon clones of Pinot Noir came into production in Marlborough, it became apparent that the best quality grapes were coming from vineyards planted on clay soils in the Southern Valleys of the Wairau. The clay soil, combined with the elevation of the vineyard and the factors that make Marlborough such a successful viticultural region - sunshine, warm days, the excellent quality of the light, cool nights and constant ventilation - all combine to make this site ideal for the production of top quality Pinot Noir.
