Greywacke is a boutique winery located in Marlborough, New Zealand, founded in 2009 by acclaimed winemaker Kevin Judd. The winery's name pays homage to the region's ancient greywacke rock formations, which influence the unique terroir of the Southern Valleys subregion where Greywacke's vineyards are planted. Focusing on small-batch production of premium Sauvignon Blanc, Pinot Gris, Riesling, and Pinot Noir, Greywacke utilizes a blend of traditional and modern winemaking techniques to craft complex, mineral-driven wines that have earned widespread critical acclaim. With only a few thousand cases produced per vintage, Greywacke embodies a boutique, artisanal approach that allows the distinctive Marlborough terroir to shine through in each bottle.
