in the vineyard : Grapes were sourced from vineyards in the Durbanville, Stellenbosch, Paarl and Darling areas. The grapes are grown in decomposed granite on slopes suiting the cultivar, ranging in altitudes at between 50 m and 150 m above sea level. The vineyards were planted between 1985 and 1995. The vines, grafted onto nematode resistant rootstock Richter 99, R110 and 101-114, are grown under dryland conditions and receive supplementary irrigation by means of an overhead sprinkler system.
