38 million years in the making...
Geological forces drove an ancient limestone seabed upwards forming the building blocks of the modern Waitaki Valley in Aotearoa, New Zealand.

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.
The Pinot Noir plantings include Burgundian Dijon clones 667 and 777 together with the renowned Abel clone, each selected for their ability to express complexity, perfume and structure within the site. Chardonnay is grown on carefully selected limestone parcels where the extended growing season allows gradual flavour development while preserving tension, vibrant acidity, freshness and fine mineral detail. While the estate has become particularly recognised for Pinot Noir, the limestone-grown Chardonnay has also emerged as an increasingly important expression of the site, combining texture, restraint and longevity with the distinctive mineral character of the Waitaki Valley.
Across the estate, warm summer days, cool nights and long autumn ripening periods contribute to slow, even physiological maturity and exceptional natural balance. Rustic limestone walls enclose the vineyard, helping moderate wind exposure and temperature variation while reinforcing the individuality of the site. Vines are managed with naturally low yields and harvested entirely by hand in multiple passes according to parcel, clone and ripeness. Vineyard practices are guided by patience, balance and long-term vineyard health, allowing each season and section of the vineyard to reveal its individuality naturally.
In the cellar, the philosophy remains restrained and site-driven, with an emphasis on transparency and the unembellished expression of vineyard character. Each vintage is approached independently according to the conditions of the season. Élevage is carried out exclusively in French oak barriques from leading coopers including Taransaud, selected to support texture, structure and longevity while preserving purity and site expression. Individual parcels and clones are blended thoughtfully to capture the subtle variations across the limestone slopes. The resulting wines are shaped by savoury minerality, fine tannin structure, vibrant acidity and age-worthy balance. The structural precision and mineral tension of the wines provide exceptional capacity for long-term cellaring and evolution in bottle.
The Roulet Magides Family traces its winemaking heritage to 1887 in Peseux, Neuchâtel, Switzerland, where viticulture formed part of a long-standing family connection to wine, agriculture and place. That multi-generational appreciation for site, season and restrained winemaking continues to shape the philosophy of Clos Ostler today.
Now regarded as one of New Zealand’s leading limestone-focused estates, Clos Ostler has received consecutive Gold Medals and significant international recognition, including the New Zealand Red Trophy and New Zealand Pinot Noir Trophy at the International Wine Challenge 2025, alongside consistent 95+ point reviews from leading international critics. Produced in highly limited quantities from a singular limestone vineyard, the wines have developed a growing reputation for their precision, longevity and transparent expression of site. Through both viticulture and winemaking, Clos Ostler continues to shape the growing international reputation of the Waitaki Valley as one of the Southern Hemisphere’s most compelling cool-climate wine regions.

RECENT RELEASES
CHARDONNAY 2024
95 pts, Candice Chow
Bright, even, pale yellow. The nose is welcoming, with aromas of flint, stonefruit, citrus, wildflowers and delicate spice. Medium-bodied, aromas of nectarine, lemon sherbet, grapefruit and its zest, intertwined with stony minerals, flint, fine spice and wildflower. The fruit is bright and lifted, flowing effortlessly alongside fresh acidity and chalky mineral on a creamy mouthfeel.

Clone 95, handpicked and whole bunch pressed, barrel fermented with wild yeast and aged in French oak for 11 months.
Notes
The 2024 vintage will be remembered as one of the finest growing
seasons in the history of Waitaki viticulture. El Niño delivered warmth
and clarity, resulting in one of the driest and warmest seasons of the past
two decades. The region enjoyed a gentle accumulation of warmth across
summer and autumn, free from the persistent late-afternoon coastal
winds that often define our ripening window. Despite the usual
turbulence of a Waitaki spring — marked by strong winds and some
frost impact — the season settled into a steady rhythm, allowing the
fruit to develop with remarkable precision. Harvest began 10 days ahead
of our long-term average, offering an extended window for careful fruit
selection.
Hand-harvested fruit, whole bunch pressed and fermented with wild yeast
in French oak barrels. A 100% barrel ferment lends texture and depth.
Aromas of white peach and ripe lychee, layered with subtle floral tones,
sit alongside a faint mineral edge, offering both aromatic lift and
complexity. A vibrant entry of succulent stonefruit evolves into a focused
core of grapefruit acidity, delivering precision and energy. The palate is
finely textured, with a mineral backbone and a thread of salinity
providing structure and drive, leading to a long, refined finish that is
distinctly expressive of the Waitaki Valley’s cool-climate elegance.
PINOT NOIR 2023
94 pts, Candice Chow
Light crimson, lighter on the rim. The nose is lifted, with aromas of raspberry, cranberry, red cherry, rosehip, dry herb and a touch of spice. Medium-light bodied, aromas of raspberry, cranberry and red cherry, intertwined with rosehip, tarragon, thyme and delicate spice.

Notes
A lifted, aromatic nose of redcurrant, cherry compote, and delicate herbal
perfumes leads the way, offering both vibrancy and nuance. The palate is
seamless and finely textured, with a subtle thread of salinity that adds
energy and tension. Beneath its elegance lies structure — finely grained
tannins and bright acidity that frame the wine and hint at its age worthiness.
EOS 2022

Wonderfully fruited and enticing, the bouquet shows dark plum, smoked game, tapenade, porcini, and roasted nut aromas. The concentrated palate delivers plump mouthfeel and velvety texture, splendidly framed by seamlessly woven tannins, making it opulent with grace and poise. At its best: now to 2037.
96 Points, Raymond Chan

95 Points, Cameron Douglas
Ripe and pure fruited with a core of red berry fruits and limestone soil scents. As the wine opens out in the glass, the earthy signature increases. Aromas of fine oak barrels and concentration of fruit show that this wine is youthful and highly energised. Dry, taut, and youthful squeeze on the palate, with flavours of cherry and raspberry, along with a strawberry compote note, then clay and limestone, oak spice, and focus. An abundance of fine tannins and a backbone of acidity frame the palate nicely. Lengthy and well-made, with the best drinking from 2029 through 2035+.
95 points, Stephen Wong
Floral and sweet; clouds of perfumed nutty, vanilla oak surround the rotating cast of dark cherry, plum and raspberry. A soft, plush, primary anise-spiced berry confit forms the core of this crystalline, pretty pinot noir. Not a blockbuster and no more than mid-weight, the pure and precise fruit is framed by light, powdery tannins before giving way to milk chocolate and spice. It can be approached now for charming delicacy but most of its intrigue will remain hidden, and it will need several years before it reveals its innate complexity. Best drinking 2025–2039
94 points, Claire Nesbitt, James Suckling
"Red plums, pomegranate and sweet mushrooms on the nose of this bright, transparent wine. Hints of licorice and rose petals. It's medium-bodied with fine, textural tannins. Layered, showing delicious savory and smoky undertones to the fruit."
CAROLINE'S 2022
96 points, Sam Kim
The bouquet is alluring and inviting with wild strawberry, sweet cherry, thyme, clove, and nutmeg aromas, followed by a silky-smooth palate that's juicy and finely flowing. Wonderfully composed and styled with refinement and harmony, leading to a persistent, velvety finish. At its best: now to 2035.
95 points, Raymond Chan
Light ruby-red, even colour throughout. The nose is lifted, with aromas of cherry plum, red date, raspberry, sweet floral and delicate spice. Medium-bodied, aromas of red cherry and raspberry intertwined with plum, vanilla, hibiscus, rose, cinnamon and earth. The wine is delicate and appealing; lacy, engaging acidity flows effortlessly, binding the red fruit core with floral, earth and gentle spices. Supple, dusty tannins lightly coat the palate and unfold spices. This Waitaki Pinot Noir is lifted and ethereal, with an enlivening and haunting closing. Match with roasted quail and pigeon over the next 10 years. Handpicked, clones 115, 667, 777, UCD6 and Abel. Fermented to 14.24% alc. 19/20 pts (95 pts) Apr 2025.
94 points, Cameron Douglas
Ripe and varietal, fruity and very new. Aroma of raspberry and cherry, plum and strawberry. A fine seam of limestone and clay soil woven through scents of barrel add complexity and intrigue. Taut, dry, fruity, and complex, a wine with an abundance of fine needle-point tannins and a backbone of acidity. Core fruit flavours mirror the bouquet. Plush, ripe, fruity, and vibrant with a lengthy and youthful finish. Best drinking from 2028 through 2034+.
94 points, Stephen Wong
Polished blackberry, violet and plum with floral notes, a seasoning of chocolaty oak and spicy, savoury complexity which unfurls in layers. The palate is tapered with fine tannin and tight acidity creating length for the youthful, backward flavours. Some charry savouriness and oak does creep in towards the back but on balance, the wine is sleek and compact, packed with black fruit and a persistent, evolving finish. It will evolve in the cellar for a decade at least. Best drinking 2026–2037
