He said “I am both relieved and happy to be the second person from my country to achieve this prestigious qualification.
Over the years, the interest in my pursuit of the Master of Wine title has been enormous.”
He has twice been named Dutch Vinologist of the Year and has written 10 books on wine.
Jean Michel Valette MW, chairman of the Institute of Masters of Wine, said: “I know that he will be an asset to the Institute and the broader wine trade in the Netherlands and beyond.”
The subject of van Casteren’s dissertation was “An Examination of Chenin Blanc as the Potential Reference Wine of South Africa”.
