Planting for the Future: The Story Behind Gaia and Nereus
In 1986, when most Australian winemakers were focused on riper, fuller styles, Jeffrey Grosset made an unconventional decision: to plant a cabernet vineyard at the highest, coolest point in the Clare Valley.
The site selection for Gaia Vineyard was meticulous. Elevation mattered—as high as possible to capture cooler temperatures. Geological homogeneity was essential for consistency and balance. The goal was clear: to make fresh, balanced wines with moderate alcohol and vibrant acidity. Wines that expressed place with precision and elegance.
But there was another consideration, one that few in the wine industry were discussing in the mid-1980s: global warming.
The Gaia principle
Jeffrey had been reading James Lovelock’s work on the Gaia hypothesis—the idea that Earth functions as a self-regulating system. The science around global warming was emerging, and the implications were clear: the world would almost certainly warm. Planting at elevation wasn’t just about making better wine in 1986; it was about ensuring we could continue making the same style of wine decades into the future.
The vineyard’s name, Gaia, reflects this forward thinking—a recognition that winemaking must adapt to our changing planet, not resist it.
Adaptive winemaking: the Nereus story
The same philosophy guided the creation of Nereus. Rather than relying solely on traditional Australian varieties and clones, Jeffrey looked to Sicily—a hot, high-sunshine region where nero d’avola thrives—and blended it with the Tahbilk clone of shiraz, a gentler, more elegant expression than the commonly planted clones in Australia.
The result is a wine that remains fresh, juicy, and approachable even as temperatures rise. Two varieties that together offer something neither could alone: a response to changing conditions, not a capitulation to them.
Embracing change
Both wines represent a philosophy: embrace change rather than be captive to old traditions when conditions have evolved and they no longer apply.
Forty years on, Gaia Vineyard continues to produce wines of freshness and balance. The evolving climate has only vindicated the original vision. This isn’t luck—it’s the result of looking ahead, understanding the forces shaping our world, and acting with intention.
Viticulture, like the planet itself, requires adaptation. At Grosset, we’ve been doing that since 1986.
