Greywacke (pronounced ‘grey-wacky’) is the name given to the grey sedimentary rock that characterises much of the soil in this estate’s vineyard. The winery was founded in 2009, and is the brainchild of Kevin Judd, former winemaker of Cloudy Bay for 25 years. The Greywacke portfolio is primarily based on two varieties, sauvignon blanc and pinot noir, the sauvignon blanc being produced in two distinctly different styles. In addition to this core range of three wines, there are also limited edition releases of chardonnay, and three aromatic varieties – pinot gris, riesling and gewruztraminer.

WINEMAKING Some vineyards were harvested by machine and others by hand, all into half- tonne bins, which were tipped directly into tank presses. The grapes were pressed lightly and the resulting juice was cold-settled prior to racking into mostly old French oak barriques. The juice was allowed to undergo spontaneous indigenous yeast fermentation, the tail end of which continued for well over six months. The wine had occasional lees stirring and approximately two-thirds underwent malo-lactic fermentation. It was transferred out of oak prior to the following harvest and left on yeast lees for a further six months. The wine was bottled in November 2017 with alcohol 14.0%, pH 3.20 and acidity 6.0 g/l.
Demeter certified. Lemon and lime zesty fruit combined with an attractive dusty quality. Already surprisingly complex on the palate, fruit and site and winemaking all working together to give piercing freshness and a finish that keeps your attention. Very good.
