i. Biography
Since 2015, Bertho van der Westhuizen has been winemaker at Alto Wine Estate in Stellenbosch, South Africa. Born and raised in Stellenbosch, he works from a close reading of site and season; on the 2014 growing year, he said, "The winter of 2014 was perfect, enough cold with good rain. When the summer came, it provided perfect growing conditions for the grapes to ripen optimally."
The Climb
Bertho van der Westhuizen began at Alto in Stellenbosch in 2003 as a harvest worker, then moved through cellar and winemaking posts at Citrusdal Cellars in Citrusdal and Kleine Zalze Wines just outside Stellenbosch. He later handled winemaking for Boschendal reds and the Brampton range of whites and reds at DGB Boschendal and Brampton, before returning to Alto Wine Estate in 2015 as cellar master and winemaker.
Today
The current appointment is winemaker, a post that began in 2015 and continues. The work is terroir-driven, with vintage decisions shaped by the conditions of the block and the season. Speaking about ripening conditions, he said, "The January and February heat waves stayed away and we had cool evenings and moderate day temperatures. This allowed grapes and tannins to ripen optimally before harvesting."
Signature
Bertho's signature wines include Alto Rouge 2015 and La Residence Heritage Blend.
