The wine industry in South Africa is undergoing an exciting period of change, both in the vineyard and in the winery. Winemakers are experimenting with new varieties of vine, as well as new clones of existing varietals such as Chardonnay and Cabernet Sauvignon. Large-scale experimentation with rootstocks is taking place to establish which planting material is particularly suited to conditions at the Cape, co-ordinated by the Vine Improvement Board.
