Franschhoek Semillon: The Heritage White Nobody Orders
Franschhoek grows some of South Africa's oldest Semillon — waxy, textured, ageless whites off century-old vines the Huguenots' plantings left behind. Here's the grape most visitors walk past, and why it's the insider's order.
The bubbles are the wine Franschhoek shows you. Semillon is the wine it keeps for people who ask.
You've had the sparkling — the valley's loud, generous calling card. Now here's the quiet one, the bottle the crowd walks past and the locals reach for. Franschhoek's second great wine is a white grape most of the world forgot it had, farmed off vines older than anyone alive, making a wine that asks a little patience and rewards it for decades. Order it, and you've told the room you know the valley.
The grape the Cape threw away
Start with the strange fact at the centre of it. Semillon — groendruif in Afrikaans, the "green grape" — was once the most-planted variety in the entire Cape. In the 1800s it was nearly everywhere, the workhorse white of the whole colony. And then, over the twentieth century, taste moved on. Semillon was unfashionable, hard to sell by name, and block after block got pulled up and replanted to grapes that shifted faster.
Franschhoek is where it survived. On the slopes around town, a handful of estates kept their old Semillon plantings in the ground — some of them more than a century old, gnarled and low-yielding, a direct line back to the pre-industrial Cape. Most of the wine world discarded this grape. This valley quietly held on. That alone makes an old-vine Franschhoek Semillon one of the more soulful glasses in South Africa.
Semillon was the grape the Cape ripped out. Franschhoek is the corner that refused to.
What old vines give you
Age changes what a vine does. Under South Africa's Old Vine Project — which certifies blocks 35 years and older — the logic is simple: an old vine drops its yield, digs deeper, and concentrates what it does carry. Franschhoek's oldest Semillon runs well past that threshold, into genuine heritage territory.
The wine shows it. Young, old-vine Semillon is understated — lemon, dried hay, a waxy edge, more texture than fruit. Give it a few years, or find a bottle that already has them, and it broadens into lanolin, honey, toasted nuts and a mouth-coating, oily richness that most whites can't reach. It's not a wine that shouts. It's a wine that lasts — the kind you can cellar for a decade and watch deepen. That slow, textural quality is precisely why it flies under the casual drinker's radar and straight onto sommeliers' lists.
Where to taste it
The names to know sit around the valley floor and up its slopes. Boekenhoutskloof — one of the most admired producers in the country — has made Semillon a serious part of its reputation, drawing on old Franschhoek fruit. La Motte, one of the grand heritage estates, works Semillon within its polished range, and Stony Brook and Rickety Bridge both champion textured, age-worthy old-vine bottlings. The Landau du Val block, on one of the valley's historic farms, is spoken of as a benchmark heritage-Semillon parcel — worth seeking by name even where there's no cellar door to link you to.
Taste it two ways where you can: as a single old-vine white, unblended, so you meet the grape head-on; and as the backbone of a Bordeaux-style white, where Sauvignon Blanc adds zip and aroma over the Semillon's weight. The second is how much of the world drinks Semillon; the first is how Franschhoek shows off.
Don't sleep on the rest of the whites
Semillon is the badge, but it isn't the only white worth your glass. Those same cool upper slopes that feed the sparkling base wine also ripen fine Chardonnay — GlenWood has built a following on barrel-fermented versions, and Cape Chamonix, high on the valley's cooler flank, makes some of the more precise Chardonnay in the district. Sauvignon Blanc grows well on the cooler sites too, taut and green-edged. Between them they round out a white-wine story that's far deeper than the reds' fame lets on.
But the one to carry away is the Semillon. It's the valley's oldest voice, the wine with the longest memory, and the surest sign you ordered like someone who'd been here before.
So far the wines have leaned pale and cool — sparkling off the high slopes, old-vine whites off the historic blocks. That's the Franschhoek most visitors expect. What surprises them is what the warm valley floor does.
Drop down off the cool ground and the story turns red. Part 4 — The Reds: Bordeaux Blends & Syrah heads to the sun-trap sites where the valley makes a very different case: not the muscular Cabernet of over the mountain, but perfumed, structured, table-first reds — and the estates that prove a cool, pretty valley can be dead serious about red wine.
Common questions
Semillon, above all — the valley's signature still white, and one of its oldest. Franschhoek farms remarkable blocks of old-vine Semillon, some more than a century old, and at their best they give waxy, lemon-and-lanolin whites built to age for decades. Chardonnay and Sauvignon Blanc grow well here too, but Semillon is the one that tells you where you are.
Young, it's understated — lemon, hay, a faint waxiness, more texture than fruit. Age it, or find a bottle with a few years on it, and it deepens into lanolin, honey, toasted nuts and a broad, oily richness that coats the palate. It's not a loud wine. It's a long one, and that slow, textural quality is exactly why sommeliers rate it and casual drinkers walk past it.
Because most of it got pulled up. Semillon — known locally as groendruif, the 'green grape' — was once the most-planted variety in the Cape, but it fell out of fashion across the twentieth century and vineyards were replanted to trendier grapes. Franschhoek is one of the few places that kept its old blocks, which is why a century-old Semillon vine here is a genuine living relic.
Almost always dry. The signature style is a dry, textured white — sometimes barrel-aged, sometimes bottled as a single old-vine parcel, sometimes blended with Sauvignon Blanc for a Bordeaux-style white. Semillon is also the classic base for botrytis dessert wines elsewhere in the world, but in Franschhoek the story is the dry, age-worthy version.
Glossary
- Semillon
- A white grape, historically Franschhoek's most-planted variety and once dominant across the Cape, known locally as groendruif ('green grape'). It gives textured, waxy, age-worthy whites, and the valley still farms heritage blocks over a century old.
- Old vine
- A vineyard old enough to have dropped its yields and deepened its concentration — in South Africa, the Old Vine Project certifies blocks 35 years and older. Franschhoek's oldest Semillon plantings run well past a century.
- Bordeaux-style white
- A dry white blend built on Semillon and Sauvignon Blanc, the pairing of Bordeaux's white wines — Sauvignon for zip and aroma, Semillon for weight and ageing power.
