Marco Ventrella
"After spending more than a decade in the Hospitality industry Marco Ventrella at 29 years old, decided to Study Viticulture at Elsenburg Agricultural College.
He started his career as a technical assistant at Graham Beck in 2003. Only a year later he became the Group Viticulturist, overseeing all four Graham Beck farms and all the buying of grapes and wine, a position he held for seven years.
Marco joined KWV in November 2010 as Chief Viticulturist responsible for Grape purchasing, Grower relationships and Wine style management in the vineyards. In mid-2011 took oversight of the buying in of Bulk and Rebate wine for KWV. With 54 Farms spread over the Western Cape to visit and work with his office is most often his vehicle or any of the 425 vineyards in his care.
2019 was his 16th vintage in the Western Cape and he is still looking for that “normal” vintage the textbooks promised.
Marco likens the challenges and mysteries of wine making in the vineyards to “playing seven games of chess at the same time”. The relationship and interaction between geology, soil, climate, topography, cultivar, rootstock and practises constantly changes and shifts.
“Every move on every board affects every other board, but you can’t predict with certainty how,” he says.
