Grosset excited about 2016 rieslings
Jeffrey Grosset announced his 2016 rieslings as the most exciting new releases in more than a decade.
That is some statement, as these wines never have an ‘off’ vintage.
These days, the new vintage release of Grosset Wines includes the customary Springvale Watervale riesling, the Polish Hill Riesling, the Alea off-dry riesling, and the semillon sauvignon blanc – but also a new wine called Apiana, which is a blend of 50:50 Clare Valley fiano and semillon.
The differences between rieslings from the Polish Hill River and Watervale sub-regions – particularly Grosset’s – have long fascinated wine lovers.
The most obvious difference in the vineyard sites is that Watervale has soft rock, a kind of limestone called calcite, whereas Polish has blue slate, which is a hard rock.
What does this do to the taste of riesling?
Grosset drew a graph like this on a white board. The vertical axis represents flavour intensity, the horizontal is persistence.
Even more graphic was a photograph of two riesling bunches on their day of harvest. The Polish Hill bunch was significantly smaller in size with smaller berries and more yellow colouring. The Springvale was a larger bunch (about double the size) with greener colouring. According to Grosset, this is normal. The mixture of clones is the same in both vineyards, and winemaking and viticulture are identical – so any differences in the wines are directly because of the site differences.
