Greywacke is the Marlborough label of the Judd family and the name of New Zealand’s most abundant bedrock. Established in 2009, Greywacke is truly a family affair, with a small, dedicated team running the company from Greywacke HQ in the heart of Marlborough’s Omaka Valley. Sourcing prime fruit from mature vineyards within Marlborough’s central Wairau and Southern Valleys, the Greywacke team use low-intervention winemaking to create wines characterised by their concentration, elegance and individuality.
