The estate is situated in Stellenbosch and has 10 hectares of vineyards. It was bought by two engineers from the famous Simonsig cellar. Rouana still supplies 30% of their Shiraz crop to Simonsig because of its exceptional quality. In return the wines of Rouana are made by the enologues of the Malan-Vintners family that importantly shaped the reputation of South African wines throughout their history. GEOGRAPHY South Africa can claim her own grape variety in the Pinotage, a cross between Pinot Noir and Cinsault (known locally as Hermitage). Pinotage was bred in 1925 by Dr. Abraham Izak Perold, the first Professor of Viticulture at the University of Stellenbosch. South Africa is also notable as the second home of Chenin Blanc, known locally as Steen. However there is a lot of dreary white wine produced from some low quality clones of Steen and Colombard. The grapes known locally as red and white Muscadel are probably Muscat Blanc à Petits Grains demonstrating its variable colouring. In 2006, SAWIS (South African Wine Information and Systems) reported[5] that the country had 100,146 hectares of vineyards, with about 55 percent planted to white varieties. See table (right) for the major varieties planted in South Africa. Other grapes include Riesling (known locally as Weisser Riesling), Crouchen (known as Cape Riesling), Trebbiano (Ugni Blanc), Sémillon (Groendruif) and Muscat (Hanepoot).[6] Stellenbosch is a university town south of Paarl, about 50km southeast of Cape Town. It is the heart of South Africa's greatest wine region, notable for the number of small wineries concentrating on red wines, including many of South Africa's best. It includes the Banghoek, Bottelary, Devon Valley, Jonkershoek Valley, Papegaaiberg, Polkadraai Hills and Simonsberg-Stellenbosch wards.
