The man behind South Africa's leading wine brand has begun work on a "vineyard to bottle" initiative that monitors grape quality and ensures co-operative growers are farming ethically. It is a big change for a brand that previously bought the finished product in bulk from brokers, according to Jack.
"It's a huge project for us, for the first time Kumala will have a true grape source. It's all about traceability - knowing where the grapes come from and what has gone into every bottle," he said.
"I don't want to stand behind a brand and not know if the farm er is trading in the right way, such as having running water, a cr èche for the kids
and conserving natural flora and fauna."
Jack has also revealed plans to make the entire Flagstone range organic within the next five years. "Twenty-five per cent of our growers are now organic
and Applesdrift Farm is 100% organic. It's not just that it's better for the environment - organic grapes make better,
more balanced wine."
Flagstone was sold to Constellation in February in a deal that saw Jack take over the viticulture and winemaking for all
of Constellation's South African wine brands.
