Nina-Mari was born and raised in Pretoria. Although her father wanted her to follow in his footsteps and become a doctor, he was supportive of her studying to become a winemaker as he has always been a wine lover. Upon completing her studies in Viticulture & Enology at Stellenbosch University, Nina-Mari worked as an Assistant Winemaker at Boekenhoutskloof. Marc Kent then arranged for her to go and do a harvest with a friend in Bordeaux, Vignobles Despagne. Nina-Mari subsequently applied and worked as a harvest help at Thelema. Always up for a challenge and eager to learn more, she completed her studies as a Cape Wine Master 2014. The first Mont Blois wines was launched this year and is already receiving high praises from the likes of Tim Atkin, Christian Eedes, Tim James and Myrna Robins.
