Greywacke Wild Sauvignon

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. 
Fruit for Greywacke Marlborough Wild Sauvignon was sourced from various vineyard sites in the Southern Valleys and the central Wairau Plains, specifically in Woodbourne, Renwick and Rapaura. Soil types vary from the young alluvial deposits of Rapaura and Renwick, which contain high proportions of greywacke river stones, to the older and denser clay-loams of the Southern Valleys. A high percentage of the vineyards were trained using the divided Scott Henry canopy management system, with the balance on two- or three-cane VSP (vertical shoot positioning).
The wild in the title refers to the strain of yeast used.
Imagine an almond cake full of white nectarine, blood orange and melon laced with linseed, tarragon and lightly smoked tea. This is an alternative style that is both intricate and textural, a concoction created by fermenting entirely with naturally occurring yeast.
