Pre-Phylloxera — Australia’s Most Important Wine Story
In the late 19th century, phylloxera — a soil-dwelling vine louse — swept through the vineyards of France, Germany, Spain, and most of Europe with catastrophic efficiency. Over two decades, it destroyed the root systems of millions of vines, wiping out centuries of viticultural heritage. The solution, eventually, was to graft European vines onto resistant American rootstock — a workaround that has defined European viticulture ever since.
Australia largely escaped the epidemic. The isolation of the continent, combined with the quarantine measures that restricted vine importation, meant that phylloxera reached only limited areas (parts of Victoria and New South Wales). The Barossa Valley — where German and British settlers had planted vines from the 1840s onward — was never affected. As a result, the Barossa contains some of the oldest own-rooted (ungrafted) vineyards in the world: Shiraz plantings that date to the 1840s, 1850s, and 1860s, their original root systems still in the ground, their vines gnarled and ancient above the red-brown soil.
These pre-phylloxera vines are one of the wine world’s irreplaceable treasures. They produce tiny quantities — sometimes just a kilogram or two of fruit per vine — of extraordinary concentration and complexity. The Barossa Old Vine Charter , established by the Barossa Grape and Wine Association, formally classifies and protects vines by age: Old Vine (35–70 years), Survivor Vine (70–100 years), Centenarian Vine (100+ years), and Ancestor Vine (125+ years). The last category includes fewer than 70 individual vineyard blocks in the world — and a significant proportion of them are in the Barossa.
Grange — How Max Schubert Built Australia’s Most Iconic Wine
In 1950, Max Schubert, head winemaker at Penfolds, visited Bordeaux and was struck by the longevity of the great Cabernet-based wines he tasted there. He returned to Australia determined to create something similar — a wine built to age for decades, assembled from the best available fruit, impervious to time. The problem: Australia had no Cabernet Sauvignon of note. What it had, in the hot red soils of the Barossa and McLaren Vale, was old-vine Shiraz of remarkable concentration.
Schubert’s solution was to blend Shiraz — primarily from the Barossa — across multiple regions and multiple vineyards, applying a consistent approach of extended maceration, American oak maturation, and assemblage across vintages when necessary. The first Grange Hermitage (as it was then called) was produced in 1951. It was initially rejected by Penfolds’ board as too unusual, too unlike conventional Australian wine, and Schubert continued making it in secret. Eventually, when the early vintages began to show their extraordinary development in bottle, the wine was formally released. Today, Penfolds Grange is the most celebrated and consistently valuable Australian wine, one of the few New World wines to command a place among the world’s greatest bottles.
What Grange demonstrates is the particular genius of the Barossa’s old-vine Shiraz: the fruit has sufficient concentration to carry years of oak maturation and decades in bottle without losing its essential character. The wine’s signature — dark plum, chocolate, earthy spice, tar, and leather, with a silky richness that never tips into flabbiness — is wholly dependent on the raw material. Without the Barossa’s ancient vines, Grange is unimaginable.
Barossa Floor vs Eden Valley — The Quality Divide
The Barossa region comprises two geographically and climatically distinct zones: the Barossa Valley floor and the Eden Valley plateau. Understanding the difference is essential to navigating the region’s wines.
The Barossa Valley floor — the flat, warm, red-soiled plain — is the source of Barossa’s signature power. The heat is extreme, the water retention of the clay soils significant, and the Shiraz and Grenache produced here are characterised by their density, dark fruit, chocolatey richness, and full body. Torbreck’s RunRig, Two Hands’ Ares, and Chris Ringland’s Three Rivers are all valley-floor expressions of this opulent style.
The Eden Valley , reached by winding upward 400 metres above the valley floor to a plateau of ancient quartzite and ironstone soils, is a completely different world. The altitude brings cooler temperatures, longer ripening, and a freshness that the valley floor never achieves. Henschke’s Hill of Grace — from a single block of Shiraz vines planted in 1860 at Keyneton in the Eden Valley — is regarded by many as Australia’s greatest individual vineyard expression: powerful yet elegant, with floral complexity and fine-grained tannins that speak of altitude and old vines rather than heat and extraction.
Eden Valley’s Riesling is one of Australia’s finest white wines, and one of the most underrated wines in the world. Bone dry, extremely high in acid, with lime and slate character that makes it seem almost German in youth, Eden Valley Riesling ages magnificently — developing intense lime marmalade, petrol, and mineral notes over a decade or more. Henschke’s Julius, Pewsey Vale’s The Contours, and Eden Hall all produce exceptional examples. If you have never had a ten-year-old Eden Valley Riesling with Chinese food or grilled fish, you are missing one of wine’s great pleasures.
The most exciting current development in the Barossa is the Grenache renaissance . For decades overlooked as a blending grape, old-vine Barossa Grenache — some of it from vines predating European viticulture in most of Australia — is now being bottled as a serious variety in its own right. Cirillo’s The Vincent, from 1848 Grenache vines (if the dating is correct, possibly the world’s oldest), is a wine of extraordinary delicacy and complexity — light in colour, perfumed with strawberry and dried herbs, with a finesse that belies the grape’s reputation for heaviness. The Barossa’s old-vine Grenache story is only beginning to be told.
