The grapes that nearly disappeared and why they're back.
How a forgotten valley became South Africa’s most important address for Grenache.
For decades, Grenache played a supporting role in South African wine. It was a blender’s grape. Reliable, yes. Exciting? Not according to the market.
But in the Piekenierskloof valley, something quietly changed.
Today, this region is home to some of the oldest Grenache vineyards in the country — including blocks planted in the early 1970s. It also holds the largest concentration of Grenache plantings in South Africa.

Irrigation. None, ever.
The terroir that changes everything
The answer lives in the land itself. At 650–700 metres above sea level, nights in Piekenierskloof drop sharply even in summer. That cold air slows the ripening cycle — which is exactly what Grenache needs to develop complexity rather than just sugar.
- High altitude — 650–700 metres above sea level
- Cool nights, warm days — slow, even ripening over a longer season
- Dryland bush vines — no irrigation, ungrafted, own-rooted
These conditions force the vine to work harder. Roots push deeper into sandy loam in search of moisture. Berries stay smaller. Flavour concentrates. The cellar doesn’t need to compensate — because the vineyard already did the work.
"Less need for cellar manipulation. The vineyard already does the work."
Grenache is no longer a footnote.
It's a headline.
The Grenache revival in South Africa isn’t a trend that arrived from elsewhere. It was discovered here, in this valley, by growers who never stopped believing in a grape the market had largely written off. The fact that those vines are still standing — still producing — is the proof.
Piekenierskloof is now the reference point. The benchmark. The reason winemakers across the Cape are looking north and asking what took them so long.
