The concept
What is Regolith?
The word Regolith refers to the layer of loose, fragmented rock and soil material that sits above the solid bedrock — the ancient geological foundation beneath our feet. It is, in essence, the bridge between the deep earth and the surface world. In winemaking, it is this layer — and what lies beneath it — that defines the character of the wine above it.
This series was born from a simple but obsessive question: what happens to Grenache when it draws from three completely different ancient soils? The variety is the same across all three wines. The winemaker is the same. The vintage conditions are the same. What changes is the earth. And what the earth gives each wine is profound.
Clare Valley's ancient geology makes it one of the most geologically varied wine regions in Australia. Limestone plateaus, ironstone ridges, and quartzite creek beds — all within a few kilometres of each other, all producing wines of completely distinct character. The Regolith Series is our attempt to let that geology speak without interference.

Limestone Grenache
Bryksy Hill Vineyard · Watervale
Bryksy Hill is a site that earns its reputation through position. One of the highest single vineyard sites in Watervale, the vineyard runs east to west — a rare orientation that provides critical protection from the afternoon sun in difficult, hot vintages. Where other vineyards struggle, Bryksy Hill holds its composure.
The result is a Grenache of genuine elegance. Bright red fruit, floral lift, and that distinctive chalky tannin structure that only limestone-derived soils can produce. This is not a fruit-forward crowd-pleaser — this is a wine of texture, detail and restraint. It rewards attention.

Ironstone Grenache
Glen Kelly Vineyard · Springfarm Road · Clare Valley
Some vineyards have history. Glen Kelly's Springfarm Road site has the oldest Grenache vines in Clare Valley — planted in 1932. These are bush vines of extraordinary age, grace and concentration, the kind that have survived drought and flood and decade after decade of Clare Valley seasons with a quiet, stoic dignity.
The rich red soil over ironstone drives a wine of depth, savouriness and structure. Darker fruit than the Limestone, with an earthy mineral backbone that only ancient vines can produce. This is the wine of the three that will age most gracefully — complex, layered, and completely unforgettable.
The east-west orientation of these beautiful old bush vines ensures even ripening across an impressive site. When you hold a glass of the Ironstone, you are drinking from one of Clare Valley's most historically significant pieces of ground.

Quartzite Grenache
Crabtree Estate Vineyard · Watervale
Beneath the Crabtree estate runs the ghost of an ancient creek — a watercourse that carried water through this valley when Clare was first being settled. That creek is long gone. What it left behind is something extraordinary: dark Bay of Biscay soil over a quartzite regolith that gives this parcel of the estate a character unlike anything else we grow.
The softest and most delicate of the three expressions, this wine has a purity and transparency to its fruit that is deeply compelling. Fine-boned, mineral and long — this is a Grenache for those who want to think. It is a wine of remarkable subtlety, and a reminder that our own estate holds geology we are still learning to understand.
