Founded in 2009, Greywacke is Kevin Judd's Marlborough label, and fulfilling a long dream. The name of Greywacke was adopted by Kevin and his wife Kimberley for their first Marlborough vineyard in recognition of the high prevalence of rounded Greywacke River stones in vineyard soils.


Judd was the founder winemaker of Cloudy Bay and directed their first 25 vintages. He played a key role in establishing the region's reputation and developing the style of wine that has become synonymous with Marlborough wines; piercing mineralization, deep acidity and aromatic expressions.
