As South Africa raises its export volumes of mostly bottled wines, it also increases its carbon emissions. “So it becomes a delicate balancing act to enhance our sustainability profile while pushing up our output,” says Su Birch, CEO of Wines of South Africa (WOSA).
And one of the answers lies in reducing the weight of the bottles.
“New 350 gram glass bottles for red and white wines have been designed to accommodate screwcap closures, which account for over 65% of South Africa’s wine production. They are scheduled for launch by mid-April, in time for the 2010 harvest,” said Birch.
At the same time, the average weight of bottles sealed with corks has been reduced in weight from 570 grams to 460 grams, she said.
