Greywacke

Greywacke is a highly regarded winery located in Marlborough, New Zealand, known for producing outstanding Sauvignon Blanc and Pinot Noir. Established by Kevin Judd in 2009, Greywacke reflects his deep experience as the founding winemaker at Cloudy Bay, where he helped shape the international reputation of Marlborough wines. 

History of Greywacke Estate

The story of Greywacke begins with Kevin Judd, one of the leading figures in New Zealand's wine industry. Born in England and raised in Australia, Judd moved to New Zealand in 1983 to pursue winemaking. His work as the founding winemaker at Cloudy Bay, one of Marlborough’s most famous wineries, catapulted the region to international fame, particularly for its Sauvignon Blanc. Over his 25-year career at Cloudy Bay, Judd helped shape the style of Marlborough’s wines, known for their vibrant acidity and intense fruit flavors.

In 2009, after leaving Cloudy Bay, Judd founded Greywacke as his own independent project, allowing him to focus on crafting wines with a more artisanal, hands-on approach. Initially producing the wines at Dog Point Winery, another notable Marlborough estate, Greywacke became a standalone brand that quickly gained a reputation for quality. Judd named the winery after the greywacke stones that are scattered throughout Marlborough’s vineyards, symbolizing the estate’s deep roots in the local soil.

Greywacke remains a family-run business, with Judd overseeing both the vineyard management and winemaking. His wife, Kimberley, also plays an integral role in the estate’s operations. With a small but dedicated team, Greywacke has established itself as one of Marlborough’s top boutique wineries, producing wines that are both complex and expressive of the region’s terroir.

Region and Vineyards

Greywacke sources its grapes from some of the finest vineyards across Marlborough, focusing on the Southern Valleys and Wairau Plains. The region is New Zealand’s premier wine-growing area, benefiting from a cool maritime climate and long growing season. This combination of climate and geography enables Greywacke to produce wines with intense flavors, vibrant acidity, and a remarkable sense of place.

The Southern Valleys, where Greywacke’s Pinot Noir is primarily sourced, is known for its clay-rich soils, which contribute texture and complexity to the wines. The vineyards here benefit from warmer temperatures, allowing the grapes to achieve full ripeness while maintaining freshness. The Wairau Plains, on the other hand, are characterized by stony, alluvial soils that drain freely and are ideal for growing Sauvignon Blanc. These soils, combined with the region’s abundant sunshine, produce wines with bright fruit flavors and crisp acidity.

Greywacke’s vineyards are managed with sustainability at the forefront, and many of the sites are organically farmed. The winery adheres to Appellation Marlborough Wine (AMW) guidelines, ensuring that its wines meet the highest standards of provenance, quality, and environmental stewardship. Greywacke focuses on low yields to ensure the concentration and quality of the fruit, with hand-harvesting and meticulous vineyard care throughout the growing season.

Wine Range

Greywacke is best known for its iconic Sauvignon Blanc, which combines vibrant tropical fruit flavors with subtle complexity from wild fermentation. The range also includes:

• Wild Sauvignon: A more complex, oak-aged expression of Sauvignon Blanc, fermented with wild yeasts to add depth and texture.
• Pinot Noir: Elegant and structured, Greywacke’s Pinot Noir showcases red fruit, spice, and earthy undertones, reflecting the diverse terroirs of Marlborough.
• Chardonnay: A rich and textured wine with notes of stone fruit, citrus, and integrated oak, made in a style that balances freshness with complexity.
• Riesling and Gewürztraminer: Small-batch aromatic wines that emphasize purity of fruit and vibrant acidity.
