Grosset Polish Hill is produced exclusively from the eight-hectare estate-owned Polish Hill Vineyard in the Clare Valley. The gently sloping site is comprised of silt and shallow shales over a thin crust of clay and gravel. This overlays a bed of blue slate, estimated to be around 500-million-years old.
This ‘hard rock’ site was originally part of a larger estate but was considered to be of limited agricultural value and so was sold off. The vines here struggle to draw nutrients from the soil, so the bunches and berries are small, and the fruit flavours lean and austere. Indeed, this vineyard exemplifies how old-rock profiles can contribute to a wine’s character.
Relatively close-planted to three clones (two German and one local), this ACO Certified Organic vineyard is completely tended by hand; hand-pruning, shoot and crop adjustment and hand harvesting ensures the delivery of pristine quality fruit.
No tillage is employed and no fertilisers are introduced: a mix of natural and introduced clovers and grasses are maintained between the vines and allowed to self-seed.
Since the first striking example of Polish Hill Riesling in 1981, Grosset has maintained a gentle and uncomplicated winemaking approach which focuses on the purity of the fruit.
The challenging rocky profile of the site and consequent low yields, results in an average of two bottles of wine per vine being produced. Polish Hill riesling
