Grosset Wines

Riesling held to a narrow line

Riesling still sets the line for Jeffrey Grosset, winemaker at Grosset Wines in Auburn Sa, where the cellar work begins with fruit from the cool high country of Clare Valley. Jeffrey Grosset has held the post since 1981, after training at Roseworthy College, and that long tenure gives the place its discipline: a cellar built around consistency, restraint, and a clear view of what variety can carry when the vineyard is allowed to speak. He has said, “People associate me with Riesling and I’m fine with that.” The sentence lands without theatre because the wines have made the argument for years. Polish Hill Riesling, Springvale Riesling and Watervale Riesling form the working language of the house, each one tied to site rather than to a general style. Gaia Cabernet Sauvignon gives the cellar another register, but it follows the same method, a wine named for a vineyard rather than a mood.

High country, hard rock, small production

The vineyards sit in Clare Valley’s coolest high-country locations, at 460–560 metres above sea level, with estate fruit grown in an organic and biodynamic program. North of the winery, the sites give Grosset the materials he has chosen to work with: Riesling, Cabernet Sauvignon, Cabernet Franc, Chardonnay, Pinot Noir, Fiano and Semillon. Gaia has its own severity. Established in 1986 below Mount Horrocks, the vineyard stands at 570 metres as the region’s highest vineyard, with two hectares of Cabernet Sauvignon and Cabernet Franc in isolated, windswept ground where hard red rock predominates. Those figures matter because they explain the cut and carriage of the wines better than a tasting note can. The house frames the work as pure expressions of variety and place, and the cellar follows that premise the long way, through harvested bunches, site separation and patient handling rather than ornament.

The cellar door kept close to the work

The room in Auburn is quiet by design, more cellar-door bench than stage. The setting holds to the scale of a small family operation, with the tasting room close to the winery and the vineyards further north in the high country. The mood suits the wines: focused, restrained, built for attention rather than interruption. At the counter, the sequence can move from Riesling into Cabernet, Chardonnay, Pinot Noir, Fiano or Semillon without losing the thread, because the thread is not variety alone. It is altitude, cool exposure, and the hand of a maker who keeps structure as close in mind as aroma or length. The place does not need much decoration when Polish Hill Riesling is in the glass.

Why Gaia remains part of the argument

Gaia keeps the range from becoming a single-variety story. Grosset has said, “The first vineyard I planted was Gaia – two hectares of Cabernet.” That vineyard, below Mount Horrocks, gives the cellar a red wine shaped by the same conviction that drives the Rieslings: site first, then method. The next release to read here is not a change of direction but another vintage passing through the same narrow gate, from Gaia’s hard red rock to Gaia Cabernet Sauvignon.
