Despite adverse weather resulting in a smaller grape harvest than usual, South Africa is producing some outstanding wines this year, according to listed company Distell, which accounts for a third of South Africa's total wine production. Erhard Wolf, the executive responsible for grape and wine supply, said yesterday that heavy spring rains, strong winds, unseasonal hail storms and a 10-day heatwave had combined to make the 2010 harvest "one of the most labour-intensive and logistically demanding vintages in recent memory".
