Clos Ostler is a small family-owned single-vineyard fine wine estate in New Zealand’s Waitaki Valley, among the earliest vineyards established in the region and widely recognised for playing a pivotal role in shaping the Waitaki Valley’s emergence as one of New Zealand’s most distinctive cool-climate wine regions. Founded on a rare limestone-enclosed north-facing hillside overlooking the Waitaki Valley, the estate was selected for its exceptional combination of ancient marine soils, elevation, sunlight exposure and climatic tension, conditions that remain both marginal and remarkably suited to fine viticulture. Planted predominantly to Pinot Noir and Chardonnay, alongside small plantings of Pinot Gris, the vineyard is dry-grown on free-draining limestone soils formed from ancient seabeds rich in fossilised marine deposits. These soils, combined with the Waitaki Valley’s continental-maritime climate, produce wines defined by mineral precision, vibrant natural acidity and layered structural depth. Central to the philosophy of Clos Ostler is the transparent expression of site, where limestone soils, climate and season are allowed to shape the wines with precision and authenticity.
