Jeffrey Grosset is founder and owner of Grosset Wines in the Clare Valley, South Australia. After graduating in Oenology and Agriculture, Grosset held winemaking positions in Australia and Europe before establishing his own winery and vineyards in 1981.
Grosset has a reputation as a no-compromise innovator focussed on wine quality and authenticity. He led the successful introduction of screwcaps to premium wine in 2000 and was instrumental in having riesling acknowledged as a grape variety in Australia’s Label Integrity laws. His latest initiative involves authentication of wine utilizing blockchain-style immutability linked to a newly designed wine closure. Grosset was voted inaugural Australian Winemaker of the Year (GT Wine) in 1998, is internationally recognised as one of Decanter UK’s ‘Top 10 White Winemakers’ and one of the ‘50 Most Influential Winemakers’ (Wine & Spirits, USA) in the world today.
Grosset Wines is a small, highly specialised winery operation concentrating on the production of eight wines. All four of its Clare Valley vineyards, site selected and planted by Grosset, are ACO certified A-grade organic and biodynamic, as is the Winery and its on-premise bottling facility.
The aim is to make pure, pristine and delicious examples of variety and place. Of the four Grosset vineyards, three are dedicated, at least in part, to production of the riesling grape. Grosset selected each of the sites through a painstaking and rigorous process, resulting in four very different terrains. By strictly following soil and rock structures, all plantings are irregular in shape and by pursuing an ideal climate, all are in high-altitude country of the region to benefit from cooler ripening conditions. The contrasting impact of site, through vastly differing geological profiles remains a highlighted attraction particularly of Grosset Rieslings, as has been the case since the first vintage 41 years ago, when ‘terroir’ was an almost unheard expression in Australia.
In pursuit of the ultimate in vineyard and varietal expression, Grosset goes beyond organic in winemaking, avoiding all fining agents through careful hand picking and selection, and precise timing of harvest. A side benefit of this strict approach is that all wines are vegan and vegetarian friendly. Combined with Grosset Wines’ carbon-neutral status, through solar power, ongoing tree planting and land regeneration, Grosset Wines aims for the highest level of sustainability while pursuing the ultimate in wine: pure expression of variety and place.
