Greystone Wines is a certified-organic estate in the Waipara Valley of North Canterbury, on New Zealand's South Island, known for limestone-influenced, clay and gravel soils over an ancient seabed that lend its wines minerality and structure. The estate practises organic and increasingly regenerative viticulture, including a distinctive vineyard-ferment programme for some wines. Its Pinot Gris is grown on these free-draining Waipara slopes, where warm days and cool nights preserve aromatics and natural acidity. The 2025 North Canterbury season conditions for this release are not detailed in the available material, but the estate's organic farming and cool-climate site consistently yield concentrated, textural Pinot Gris fruit.

In keeping with Greystone's style, the Pinot Gris is made in a dry, textural manner. Hand-picked fruit is whole-bunch pressed, with time on skins used in some parcels to build phenolic grip, then fermented cool - often with wild yeast - to retain varietal purity. Extended lees contact adds weight and a subtle savoury, nutty complexity, while a portion of older oak or neutral vessel maturation can broaden texture without overt oak flavour. The wine is bottled dry, aiming for a rounded, mineral, food-friendly Pinot Gris. Specific 2025 vinification figures were not available and are generalised from the estate's house approach.
