Description
Limestone 95 · Quartzite 94 · Ironstone 93
Two bottles of each. Three ancient soils. One question answered: what does the earth do to a wine when everything else stays the same?
The Regolith Mixed 6-Pack is the definitive way to experience the series — and the most compelling tasting exercise you can do at home. Pour all three side by side. Same variety. Same winemaker. Same vintage. Three completely different wines.
The difference between them is entirely the soil. The Limestone’s chalky brightness. The Ironstone’s ancient depth. The Quartzite’s quiet precision. Put them next to each other and you will understand Clare Valley’s geology in a way that no book and no course can teach you.
Seven Grenaches were entered in the 2025 class. All three of ours came home with medals — and the Ironstone took Gold and Best Clare Valley Grenache. The same show named Crabtree the Clare Valley’s Best Small Producer.
Ironstone – Gold, Best Clare Valley Grenache · Limestone – Silver · Quartzite – Silver
“Regolith is the layer of fragmented rock and soil above the solid bedrock — the ancient geological foundation beneath our feet. In winemaking, it is this layer that defines the character of the wine above it.”
Three sites. Three regolith types. One variety. The Regolith Series is our attempt to let Clare Valley’s ancient geology speak without interference. Andrew Kenny — Vigneron of the Year 2024, Clare Valley Hall of Fame Rising Star — made every wine in this series.
How to taste it
Side by side: Open all three at the same time. Pour a small glass of each and taste them together. Start with Limestone, then Quartzite, then Ironstone. The contrast is the point.
Over time: Open one per month and watch how each wine evolves. The Ironstone will keep changing for years. The Limestone will peak sooner. The Quartzite will surprise you at every stage.
With food: The Limestone loves lamb. The Ironstone loves slow-braised beef. The Quartzite loves something delicate — duck, quail, or a beautiful cheese platter.
