Shiraz and Syrah are the same grape. Same vine, same DNA, same origins in France's Rhône Valley, and yet ask any wine drinker to picture each one and you'll get two entirely different wines back. One is deep, generous and full-bodied. The other is lifted, peppery and restrained. Neither answer is wrong. That's the story worth telling.
One Grape, Two Names
Syrah has been grown in the Northern Rhône for centuries, forming the backbone of appellations like Hermitage and Côte-Rôtie. It made its way to Australia in 1832, brought over by James Busby, the Scotsman widely credited as the father of Australian viticulture, who collected vine cuttings across Spain and France on the voyage that shaped this country's wine industry.
What happened next is where the story gets interesting. Australia adopted the name "Shiraz" over the following decades and turned it into an internationally recognised term in its own right, distinct from its French parent even though the grape in the ground is identical.
Exactly where the name came from is a story most people get wrong. For centuries, the popular legend held that the grape travelled from the ancient Persian city of Shiraz, carried west by traders or a wandering crusader-turned-hermit who supposedly planted it on the hill that became Hermitage. It's a wonderful story. It's also not true. DNA testing settled the question beyond doubt in 1998, tracing the grape's real parents to Dureza and Mondeuse Blanche, two little-known varieties native to southeastern France. The Persian tale lingers because it's more romantic than the truth, but the truth is that this grape never left France until it came to us.
It's easy to see how the mix-up happened. Somewhere along the way, early spellings like "Scyras" coincidentally echoed the Persian city's name, and the story stuck long enough to shape what Australia decided to call the grape.
Our own family has been growing this grape since Christian Auricht first planted vines in this pocket of the Barossa in 1843, six generations back. Whatever it was called at the time, it's been part of this area for longer than most of the industry's origin stories.
Same Vine, Different Stories, Told by the Land
Here's the part that surprises people: the name itself has come to signal a style. "Shiraz" is generally associated with warmer New World sites, where the grape ripens fully and produces deep, structured wines with generous dark fruit. "Syrah" is more often used for cooler, higher-altitude sites, where the same grape tends to express itself as something leaner, more perfumed and more peppery.
That peppery character isn't just a tasting note winemakers invented for fun. It's a real, measurable compound called rotundone, and the Australian Wine Research Institute has spent years studying exactly why it shows up in some Shiraz and Syrah and not others. Their research has found that rotundone concentration climbs in cooler growing conditions and with a later harvest, which is exactly why the most peppery examples tend to come from Australia's cooler pockets rather than its warmest valley floors. Heat and early picking work against it; cool nights and patience work in its favour.
Put simply, the grape doesn't change. The climate around it does, and the wine tells you exactly which one it grew up in.
Two Sisters: Both Sides of the Story
We happen to grow both sides of this story on our own two properties, which is a rare thing to be able to say.
Our Barossa Shiraz comes from the valley floor our family has farmed for six generations: warm days, and the deep, generous structure the Barossa built its reputation on. It's the wine most people picture when they think of Australian Shiraz, and it's earned that reputation honestly.
Our 2022 Eden Valley Syrah is the newer chapter. It's our first ever release from this cooler, higher-altitude property, and it shows immediately in the glass: pepper and black plum on the nose, finer tannins, eighteen months in oak that frames rather than dominates the fruit. Where the Barossa Shiraz is bold and generous, the Eden Valley Syrah is elegant and considered. Same grape, same family, completely different personality.
If you want to actually taste what climate does to a grape rather than just read about it, open both side by side. It's one of the more interesting tastings you can do at home, and it's exactly the kind of comparison our cellar door is set up for. We're open by appointment, so if you're ever passing through the Barossa, come taste both stories for yourself.
