Grenache is the great comeback story of Australian wine. For most of a century it was the country’s workhorse — the base of cheap fortified “port” — and much of it was pulled out in the 1980s as tastes changed. What survived turned out to be a treasure: some of the oldest vines of the variety anywhere on earth, now making some of Australia’s most sought-after table wines.
A Spanish grape at home in the heat
Grenache — Garnacha in its native northern Spain, where it traces to Aragón — is a hot-climate specialist. It ripens late, tolerates drought and heat, and pushes sugar high, which is why warm-region examples can reach 15% alcohol with ease. It is also the backbone of the southern Rhône, the dominant grape of Châteauneuf-du-Pape.
Structurally it is the opposite of a heavyweight. Grenache has thin skins, so it gives a pale-to-medium colour and soft, fine tannin rather than the dark, firm grip of Cabernet or the density of Shiraz. What it offers instead is perfume and brightness — red raspberry and redcurrant fruit, white pepper and warm spice. Its hard wood and upright habit suit it to bush-vine (untrellised) training, the low goblet shape shading its thin skins from the sun.
The old vines
Grenache came to Australia in James Busby’s foundational 1832 vine collection, and by 1838 the country’s first Grenache was planted in McLaren Vale. Through the fortified era of the 1950s–70s it was the most-planted red in the land. Because so much of South Australia escaped phylloxera, the vines that were never grubbed out simply kept growing: Australia now holds some of the oldest Grenache vineyards in the world, many well over a century old, concentrated in the Barossa Valley, McLaren Vale and Langhorne Creek. The Barossa’s Cirillo block and Yalumba’s 1889 Tri-Centenary vineyard are among the oldest surviving plantings of the variety anywhere.
Old bush vines matter here: low-yielding, deep-rooted and dry-grown, they give small crops of concentrated, perfumed fruit that is the raw material of the modern style.
From fortified to fine
For decades Grenache’s job was blending — the cornerstone of tawny “port,” or a component in GSM (Grenache–Shiraz–Mourvèdre) blends in the Rhône mould, where Shiraz adds structure and Mourvèdre (Mataro) adds savoury grip. Estates with deep fortified roots, such as the Barossa’s Seppeltsfield, carried that heritage.
The shift came around 2010, as growers began treating old-vine Grenache as a serious single-varietal wine in its own right — picked earlier for freshness, and matured gently in large-format or neutral vessels rather than new oak, so the wood never buries the variety’s delicate perfume. Handled that way, Grenache reads less like a sunburnt fortified base and more like a fragrant, medium-bodied red with genuine transparency to site — the reason it is now spoken of as one of Australia’s most exciting red wines rather than its most old-fashioned.
