Grosset Polish Hill Vineyard
Situated just north of Mount Horrocks in the Clare Valley, the Polish Hill vineyard is a ‘hard rock’ site with shallow shale and a crust of clay marl over slate. These thin soils hamper the roots’ downward development therefore the vines struggle. The distinctively flavoured fruit typically has small berry and bunch size. Organically managed without tillage, natural composting and hand-tending have been practiced since 1996.
Grosset Springvale Vineyard
The hilltop-sited ‘Springvale’ is the highest (460 metres) and coolest vineyard in the Watervale subregion. Planted on red loam over limestone, this is a ‘soft rock’ site. This highly sustaining combination of soil and rock insulates the drought sensitive riesling vines, which produce lime-green fruit with medium-sized berries and bunches. ‘Springvale’ is named after the original property where riesling vines were first planted in the 1860’s.
Grosset Gaia Vineyard
Planted in the 1980s with cabernet sauvignon and cabernet franc, the Gaia vineyard is named after James Lovelock’s Gaia Theory. Lovelock proposed that the Earth is a single organism, reliant on the complexity and diversity of its species to maintain ecological health. At an altitude of 570 metres, this isolated and windswept vineyard has been farmed continuously for 33 years in accordance with this prescient concept.
Grosset Rockwood Vineyard
Of the two vineyards in the higher altitude north-eastern corner of the Watervale subregion, ‘Rockwood’, with its hard yellow rock and variable soils, is viticulturally the more challenging.
Grosset Adelaide Hills Vineyards
Grosset Wines’ chardonnay, pinot noir and sauvignon blanc grapes are grown in three privately owned vineyards in the Adelaide Hills. In the early 1990’s Grosset was drawn to the intriguing high-acid fruit from these sites. Two are in the Piccadilly Valley, the second coldest place in South Australia and for that reason they can be accurately described as ‘marginal’. In terms of quality however, the rewards of working with such challenging sites have proved to be substantial.
It is often asked; if the Grosset Spring Releases are all but sold out by Christmas each year, then what else is there to do? Each season brings with it a crucial stage in the winemaking process.
