2025 Greywacke Sauvignon Blanc 750ml

Overview

A vibrant and generously fruited Marlborough Sauvignon Blanc from Greywacke, combining ripe tropical and stone-fruit character with savoury mineral detail and a mouthwatering citrus finish. Fruit is drawn from prime sites across the Southern Valleys and central Wairau Plains, with predominantly stainless steel fermentation complemented by a small portion fermented naturally in old oak barrels.

Vineyard

Fruit was sourced from several prime vineyard sites in Marlborough’s Southern Valleys and the central Wairau Plains, specifically Woodbourne, Renwick and Rapaura. Soils range from young alluvial soils containing high proportions of greywacke river stones in Rapaura and Renwick to the older, denser clay-loams of the Southern Valleys.

The majority of vineyards were trained using the divided Scott Henry canopy management system, with the balance on two- or three-cane VSP trellising.

Winemaking

The Sauvignon Blanc grapes were harvested largely by machine during cool, often cold, night-time conditions and transported to Greywacke’s winery in the Omaka Valley. The fruit was lightly pressed to yield a modest volume of high-quality juice, which was then cold-settled and racked prior to fermentation.

Fermentation was primarily carried out in stainless steel tanks with cultured yeast, while a portion underwent spontaneous indigenous yeast fermentation in old oak barrels. Individual vineyard batches remained on lees until blending. The wine was bottled in early August.

Producer Tasting Notes

Greywacke: “Picture a summer picnic table – vases of white blossom, a vibrant salad of aromatic herbs with soft, yellow peach, crunchy pear and a squeeze of juicy lime; apricot sponge cake and custard tarts – a sweet-scented array of ripe deliciousness. On the palate, flavours of honeydew melon and white nectarine mingle with savoury notes of crushed seashells and a hint of chalky minerality. A fruit-driven Marlborough style with generosity and weight, it delivers a luscious sense of ripeness that finishes with a mouthwatering lemon-sherbet zing.”

Critic Reviews

94 Points — Cameron Douglas MS
“Ripe and fruity, core varietal scents of cape gooseberry and fresh basil, pineapple and mango, grapefruit and citrus peel. A wine with a deep core of minerality as well suggesting a silty soil and stony earthy suggestions. Taut and dry, an electric acid line with a natural fruit sweetness quality delivering contrast and flavour. As the wine warms on the palate the flavours expand with some lime and orange melon, dried herb and stone. An excellent example with best drinking from day of purchase through 2031.”
