Diemersdal wine maker Thys Louw had just finished the first stage of the world’s toughest mountain-bike race, the Cape Epic, when he heard that he’d won two gold medals. Not on the bike, but at the Concours Mondial du Sauvignon 2018, the world’s premier international showcase for Sauvignon Blanc wine. Diemersdal took gold for the MM Louw 2016 and Eight Rows 2017, two of the wines from this Durbanville estate renowned for its interpretations of South Africa’s and one of the world’s most popular white wine varieties.
