In February this year, Constellation Europe completed the purchase of South African winery Flagstone. The purchase, initially announced last October, saw Flagstone's viticulturalist and winemaker, Bruce Jack, join Constellation as chief winemaker for South Africa, with a view to revitalising its flagship South African wine brand, Kumala. In this month's just the answer interview, we talk to Jack about his role so far, what he hopes to achieve with Kumala and what the prospects are for South Africa's wine industry overall.
