Clos Ostler Vineyard

The beautiful yet challenging environment of the Waitaki Valley makes viticulture demanding but yields exceptional results for winemakers. Clos Ostler’s story began some 38 million years ago, as geological forces lifted an ancient limestone seabed to shape what would become the foundation of modern Waitaki Valley in Aotearoa, New Zealand. 

Today, the valley hosts one of New Zealand’s most distinctive wine-growing climates, perched near the very edge of viable vine-growing conditions. The poor soils encourage vines to grow deep, while powerful winds and a cool climate allow grapes to ripen slowly, preserving acidity under warm daytime sun. This "stressing" of the vines produces low-vigour plants, yielding grapes that are lower in volume but rich in flavour, complexity, and concentration. Clos Ostler possesses the most active and limestone rich soils in New Zealand, and grows some of Burgundy's most revered clones establishing itself with many parallels to Domaine Romanée Conti.

Clos Ostler’s terroir offers a variety of altitudes, soil types, and microclimates. Paired with diverse Pinot Noir clones, these factors produce some of New Zealand’s most nuanced and complex wines—distinctive expressions that truly reflect this unique site.

“Seductive and immensely complex, the enticing bouquet shows dark berry, dried porcini, warm spice and cedar characters. The palate exhibits outstanding concentration and depth, gracefully framed by rich texture and beautifully melded tannins. Plush and seamless with an impressively long, expansive finish. At its best: now to 2036.”

"This is a stunning wine from an isolated area in the far south of New Zealand's South Island. Wonderfully lush texture fills the mouth and the wine has a meaty savouriness to go with it's black cherry and dark plum fruit and a perfume like the rising sap of Springtime."

“Complex, pure and enticing bouquet of mineral chalky soils and ripe fruits of dried raspberry and dark cherry, boysenberry and soft dried herbs suggesting sage and thyme. The use of oak is specific and precise with scents of mostly new barrel with some older. As the wine touches the palate the flavours of oak strike first then give way to the core fruit and mineral flavours from the bouquet then dried herb and savoury complexities. There’s a tautness to the palate with an abundance of polished tannins and barrel spice, plenty of acidity and a complex finish. A wine for the cellar with best drinking likely from 2028 through 2038+.”
