Koos Grenache doesn’t hesitate.
“It’s syrah,” he says. “Big, bold, unapologetic.”

Professor Octavius Pinot raises an eyebrow.
“It is Syrah,” he replies calmly. “Structured, elegant, and historically grounded.”

Isabella Rioja smiles.
“And just like that,” she says, “we’ve arrived at the heart of the matter.”

Where It Really Comes From (And Where It Doesn’t)

For years, a romantic story circulated that Shiraz came from the ancient Persian city of Shiraz in modern-day Iran.

“It’s a lovely story,” Octavius says, “but entirely incorrect.”

Modern DNA analysis has shown that Syrah originates from France’s Rhône Valley, the result of a natural crossing between two obscure local varieties:

• Dureza (a dark-skinned grape from the Ardèche)
• Mondeuse Blanche (a white grape from Savoie)

So despite its exotic name, Syrah is unmistakably French.

Koos shrugs.
“Still sounds better than Dureza,” he says.

The Old World: Syrah as a Standalone Star

Unlike Semillon, Syrah has long been bottled as a single varietal in Europe — particularly in the northern Rhône.

Appellations like:

• Hermitage
• Côte-Rôtie

produce some of the world’s most revered Syrah wines.

“These wines,” Octavius explains, “are not about power. They are about structure, perfume, and restraint.”

Typical characteristics:

• black pepper
• violets
• dark fruit
• savoury, almost meaty notes

Côte-Rôtie even allows a small addition of Viognier — not to soften, but to lift aromatics.

“So no,” Isabella adds, “Syrah is not hiding in blends. In the Rhône, it is the story.”

The New World: Enter Shiraz

When Syrah travelled to the New World, particularly to Australia, something changed.

The climate was warmer. The fruit ripened more fully. The wines became:

• richer
• rounder
• more fruit-driven

And somewhere along the line, the name shifted.

“Shiraz,” Koos says, “just sounds like it’s going to give you a proper glass of wine.”

Australia embraced Shiraz as its flagship red — bold, generous, and approachable.

And then came one of the most famous wines in the world.

Penfolds Grange: The Wine That Changed Everything

No Shiraz story is complete without Penfolds Grange.

Created by Max Schubert in the 1950s, Grange was initially controversial.

“It was too big, too different, too ambitious,” Isabella says.

Penfolds even tried to stop production.

“But Schubert continued making it in secret,” Octavius adds, “which is either dedication — or defiance.”

Koos grins.
“Sounds like my kind of winemaker.”

Over time, Grange proved itself:

• extraordinary ageing ability
• global recognition
• benchmark status for Shiraz

“It showed,” Isabella says, “that power and longevity could coexist.”

Oak: Where the Style Difference Becomes Obvious

Isabella Rioja lifts her glass slightly.
“There’s something else we haven’t mentioned,” she says. “And you can taste it before you even identify the fruit.”

Octavius nods.
“Indeed. Oak.”

In the Old World — particularly in the Rhône — Syrah is typically matured in French oak, or sometimes in older, neutral barrels where the wood influence is subtle.

“These wines,” Octavius explains, “are not shaped by oak. They are framed by it.”

The result is:

• structure rather than sweetness
• spice rather than vanilla
• integration rather than impact

Koos smirks.
“In other words — you don’t taste the barrel first.”

Shiraz and the American Oak Signature

In Australia, however, a different approach took hold.

Shiraz — especially in its more classic expressions — has often been matured in American oak, which brings a very different profile:

• vanilla
• coconut
• sweet spice
• richness and roundness

“Now you definitely know the barrel is there,” Koos says.

And nowhere is this more evident than in Penfolds Grange.

Grange’s use of American oak is not incidental — it is intentional, and part of what gives the wine its unmistakable character.

“It’s not just the grape,” Isabella adds.
“It’s the way the wine is built.”

South Africa: A Quiet Preference

South Africa, interestingly, has taken a more consistent path.

Whether labelled Syrah or Shiraz, most premium South African producers tend to favour French oak — often with a light touch.

“Here,” Octavius says, “the emphasis is on balance rather than imprint.”

You’ll typically find:

• more restrained oak influence
• greater focus on fruit purity and texture
• integration rather than overt flavour

“It’s less about making a statement,” Isabella adds,
“and more about letting the wine speak.”

Not a Rule — But a Tendency

Of course, the lines are no longer fixed.

Modern producers across the world now:

• experiment with both French and American oak
• use larger or older barrels
• reduce oak influence altogether

“Style today is a choice,” Octavius says,
“not a constraint.”

But historically — and stylistically — the distinction still helps explain the difference:

• Syrah → French oak, subtle, structural
• Shiraz → American oak, expressive, flavour-driven
• South Africa → predominantly French oak, balanced and integrated

Koos raises his glass.

“Same grape,” he says.
“Different furniture — and some people just prefer it understated.”

Shiraz vs Syrah: Style or Marketing?

So what’s in a name?

Koos doesn’t hesitate.
“Marketing,” he says. “Syrah sounds expensive. Shiraz sounds like a good time.”

Octavius pauses.

“There is some truth in that,” he admits.
“But there is also a stylistic signal.”

Generally speaking:

• Syrah suggests:
  • cooler climates
  • structure and restraint
  • savoury complexity
• Shiraz suggests:
  • warmer climates
  • fuller fruit expression
  • richness and approachability

“But it is not a rule,” Isabella adds.
“It is a choice.”

Producers increasingly use the name to signal intent — not geography.

South Africa: Walking the Line

South Africa sits comfortably between Old World and New World styles — and nowhere is this more evident than with Syrah/Shiraz.

“Here,” Octavius says, “the grape has found balance.”

You’ll find:

• cooler-climate Syrah with Rhône-like elegance
• warmer-climate Shiraz with generosity and depth

One landmark moment came with the 1994 Stellenzicht Syrah, which helped establish the name Syrah locally.

It also helped put André van Rensburg firmly on the map.

“That wine,” Isabella says, “changed perceptions. It showed that South Africa could do refinement — not just power.”

Where Else It Thrives

Beyond France, Australia, and South Africa, Syrah/Shiraz has found success in:

• California
• Chile
• Argentina
• parts of New Zealand

Each region brings its own interpretation — from peppery and restrained to rich and fruit-driven.

“It’s one of the most adaptable grapes in the world,” Octavius notes.

Koos Grenache Has the Final Word

Koos swirls his glass slowly.

“You can call it Syrah if you want to impress people,” he says.
“Or Shiraz if you just want to enjoy it.”

He takes a sip.

“But at the end of the day, it’s the same grape. Same roots. Same potential.”

He leans back.

“The difference isn’t the name. It’s what you do with it.”

The Uncorked & Curious Takeaway

Syrah and Shiraz are not two grapes — but they are often two expressions of the same idea.

From the slopes of the Rhône to the warmth of Australia and the balance of South Africa, this grape has proven both versatile and enduring.
