(Bloomberg) -- South Africa’s wine producers, with a history dating from 1655 and the Dutch East India Co., expect flooding, fungus and disease to cut the grape crop this season. “Estimates are that at least 36,000 tons of grapes from the initial anticipated wine grape harvest were destroyed by floods and showers -- the figure may yet be higher,” said South African Wine Information Systems, representing all the country’s wine producers. “Grapes in many other blocks have started to rot and outbreaks of fungal disease prevail.”
