Jeffrey Grosset, an oenology graduate, gained vast experience with large Australian wine companies, such as Lindemans, before starting his own winery 21 years ago in the historic township of Auburn, in the Clare Valley. Cellar door sales and the winery are based in a picturesque old butter and ice factory, while currently 65% of the grape intake is from vineyards owned or managed by Grosset Wines. These vineyards have the most advanced vine canopy management in the region and the virtual absence of chemicals in pest and disease control is unique. The balance of grapes is carefully selected from growers who support the Grosset commitment to quality.
Riesling is the Clare Valley's famous varietal and Grosset makes two from contrasting sub-districts. The Watervale is from reddish clay-loam over limestone, the district's prized, slightly alkaline soil, which gives a lifted floral style. The other is grown at Polish Hill to the east, on more acidic quartzy soils of heavier loamy-clay over shale and slate. The wines are hand-made, classically understated and built for long keeping. Jeffrey Grosset has been held in such high esteem amongst his peers for his work with the Riesling grape that back in 1998 he won the accolade of 'Riesling Winemaker of the Year' in Hamburg, Germany. A testament to his winemaking efforts, is his Polish hill Riesling being rated in the Langton’s classification as exceptional (only 17 wines in total and only 3 of these being white wine make this grade) alongside other iconic wines such as Penfolds Grange and Clarendon hills Astralis. Langton's Classification of Australian Wine (http://www.langtons.com.au/Wine/Classification.aspx) is a grouping of high-end Australian wines compiled by the Melbourne and Sydney based auction house Langton's, first released in 1991. The Classification is a ranking of the best performing wines based on market demand and vintages made. The Langton's Classification is split into four categories; Exceptional, Outstanding, Excellent and Distinguished.
