Greywacke Sauvignon Blanc 2017 - May 2018 Decanter review
Greywacke was created in 2009 by Kevin Judd, chief winemaker at Cloudy Bay from its inception for 25 years and instrumental in the international recognition which Marlborough Sauvignon Blanc enjoys now. The name 'Greywacke' was adopted by Kevin for his first Marlborough vineyard located in Rapaura in recognition of the high prevalence of rounded greywacke river stones in the soils of the vineyard, a sedimentary rock which is widely found in Marlborough. Kevin Judd is also New Zealand's finest wine photographer and has recently published a book 'The Landscape of New Zealand Wine'.
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 greywacke river stones, to the older and denser clay-loams of the Southern Valleys.
Spring was wet and mild with no frost in any of the Greywacke vineyards. Summer temperatures stepped up with December being the second warmest on record, while January saw the highest temperatures since records began. By February it was looking like an early harvest, with superb flowering conditions and a sizeable crop necessitating thinning in almost all vineyards. However, two ex-tropical cyclones brought considerable rainfall in February. Harvest started mid-March with grapes at a good level of physiological ripeness but needing careful hand-sorting to eliminate botrytis. Despite the rain, fruit was able to hang on the vine to achieve very good ripeness levels.
Harvested largely by machine during cool (often cold) night-time conditions, the Sauvignon Blanc grapes were picked into half-tonne bins, tipped directly into the tank press and lightly pressed. The resulting juice was cold-settled prior to fermentation in stainless steel, primarily using cultured yeast for cool, slow fermentation. A portion was allowed to undergo spontaneous indigenous yeast fermentation. All individual vineyard batches were left on lees and kept separate until late July, when the blend was assembled.
100% Sauvignon Blanc.
An aromatic salsa-like fusion of ripe summer fruit and fragrant Asian spices. Nectarines and yellow peaches, rock melon, grapefruit and a splash of passionfruit, mingled with ginger and lemongrass, jasmine flowers and cassis. A deliciously ripe and zesty Marlborough Sauvignon with a lemony, citrus thread that finishes crisp and dry.
