The South African wine industry will face a shortage of grapes within five years as growers reduce the acreage they cultivate, according to Distell Group Ltd. (DST), the country’s biggest wine and liquor producer. The country’s industry has oversupplied the market, particularly with red grapes and wine, for the last five years, said Erhard Wolf, Distell’s general manager for grape and wine supply. During the peak of vineyard planting, a “very optimistic view” of potential markets was taken, resulting in more vineyards being cultivated than were required, he said.
