Get to know: Greywacke, Marlborough Sauvignon Blanc
A delicious fusion of ripe summer fruits and delicate floral perfume, citrus blossom and elderflower entwined with nectarines and white peaches, mandarin and cantaloupe with a twist of lemon. Intensely flavoured, succulent and crisp with a delicate herbal infusion. A classic example of Greywacke’s interpretation of the famous Marlborough style – ripe, textural and scrumptious – with the volume turned well down.
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.
Harvested largely by machine during cool (often cold) night-time conditions, the grapes were trucked to the Greywacke winery in the Omaka Valley, where they were lightly pressed to yield a modest volume of high-quality juice. The juice was then cold-settled and racked prior to fermentation, primarily using cultured yeast in stainless steel for cool, slow fermentation. A portion of the juice was allowed to undergo spontaneous indigenous yeast fermentation in old oak barrels. All vineyard batches were left on lees and kept separate until late June, when the blend was assembled. The wine was bottled in mid-August 2022.
