Greywacke was created in 2009 by Kevin Judd, the person responsible for the ground-breaking early wines produced in Marlborough. The name 'Greywacke' was adopted by Kevin for his first Marlborough vineyard, located in Rapaura, in recognition of the prevalence of rounded greywacke river stones in the vineyard's soils. 'Greywacke' is a sedimentary rock that is widely found in Marlborough, consisting of layers of hard grey sandstone and darker mudstone.
Greywacke Marlborough Sauvignon Blanc 2020
Yellow- fleshed peaches, rock melon and blackcurrant alongside lemon icing, chamomile and hints of rose petal – this is a delicately perfumed and deliciously ripe-fruited interpretation of Marlborough Sauvignon Blanc. The palate is both subtle and textural, showing considerable ripeness and concentration, with a crisp and long, juicy finish.
Fruit was sourced from various prime vineyard sites in Marlborough’s Southern Valleys, the central Wairau Plains (specifically in Woodbourne, Renwick and Rapaura) and a spectacular river terrace site in the upper Awatere Valley. Soil types vary from the young alluvial soils of Rapaura, Renwick and the upper Awatere, which contain high proportions of New Zealand’s ubiquitous greywacke river stones, to the older and denser clay- loams of the Southern Valleys. The majority of the vineyards were trained using the divided Scott Henry canopy management system, with the balance on a vertical shoot positioning trellis.
Harvested largely by machine during cool (often cold) nights, the Sauvignon Blanc was picked into half-tonne bins, which were tipped directly into the tank press and lightly pressed. The resulting
juice was cold-settled prior to fermentation, primarily using cultured yeast in stainless steel for cool, slow fermentation. A portion was allowed to undergo spontaneous indigenous yeast
fermentation in old oak barrels. All individual vineyard batches were left on lees and kept separate until late July, when the blend was assembled.
