Greywacke Wild Sauvignon Blanc 2023
The Greywacke Wild Sauvignon Blanc 2023 is one of the most distinctive expressions of Marlborough Sauvignon Blanc. Crafted using wild indigenous yeasts and minimal intervention techniques, this small-batch New Zealand white wine delivers remarkable texture, depth, and complexity.
Produced by legendary Marlborough winemaker Kevin Judd, Greywacke’s Wild Sauvignon has become a cult favourite among wine collectors and sommeliers. Unlike typical Sauvignon Blanc, this wine is barrel-fermented with wild yeasts and aged on lees, resulting in a richer, more layered style that balances vibrant citrus with savoury mineral complexity.
With outstanding critical acclaim and exceptional drinkability, Greywacke Wild Sauvignon 2023 is a must-buy for lovers of premium Marlborough Sauvignon Blanc.

Fruit is sourced from multiple vineyard parcels across Marlborough’s Southern Valleys, Woodbourne, Renwick, and Rapaura subregions. The soils range from alluvial greywacke river stones to clay-rich valley sites, producing Sauvignon Blanc with both aromatic intensity and textural depth.
The wine undergoes wild yeast fermentation, partial malolactic fermentation, and extended lees ageing, enhancing complexity and mouthfeel before bottling.
Tasting Notes – Greywacke Wild Sauvignon 2023
This premium Marlborough Sauvignon Blanc opens with an expressive bouquet of:
• Rock melon
• Lime zest
• Ginger spice
• Toasted coconut
On the palate, vibrant flavours of lemon curd, tangelo and ripe citrus create a juicy core, supported by creamy texture and refreshing acidity. Subtle oyster-shell minerality adds a savoury edge, giving the wine remarkable balance and length.
The result is a full-flavoured, textured Sauvignon Blanc that stands apart from the typical crisp and grassy Marlborough style.

What Makes Greywacke Wild Sauvignon Blanc Unique?
Unlike most Sauvignon Blanc wines, which are fermented in stainless steel for freshness, Greywacke Wild Sauvignon is crafted using a more artisanal approach.
Wild Fermentation: Fermented with naturally occurring yeasts from the vineyard rather than cultured yeast strains.
Barrel Fermentation: A portion of the wine is fermented in older French oak barrels, adding texture and complexity.
Lees Ageing: Extended contact with yeast lees builds richness and creamy mouthfeel.
Minimal Intervention: The winemaking philosophy emphasises vineyard expression and Marlborough terroir. This approach creates a Sauvignon Blanc with Burgundian texture while maintaining Marlborough vibrancy.
