Hasher Family Estate

Cool-climate estate on the Onrus River in the Upper Hemel-en-Aarde Valley, farming Pinot Noir, Chardonnay, and Sauvignon Blanc on clay and decomposed granite soils since 1997.

The producer

Hasher Family Estate sits on the banks of the Onrus River in the Upper Hemel-en-Aarde Valley, a registered ward within the Walker Bay wine district near Hermanus. The cold Benguela Current keeps average temperatures low through the growing season, slowing ripening and preserving acidity across all three grapes grown here. Three wines, three varieties, one valley: the range is deliberately narrow, and the lead wine, Ernest Pinot Noir, carries most of the weight.

The estate was founded in 1997 and acquired in 2021 by Belgian couple Frederik Herten and Céline Haspeslagh, who relocated permanently from Europe to farm here. Their winemaker, Natasha Williams, joined in 2023 after training in oenology at Stellenbosch University. She had begun that degree in molecular biology before switching to wine in her second year. The Ernest Pinot Noir received a 98-point score from the London Wine Competition in 2025.

Notable facts

The story

The Belgian Who Found His Valley

Frederik Herten first encountered serious wine in Ribera del Duero, Spain's high-plateau red wine country, where the Tempranillo grows at altitude and cold nights stop what the sun starts during the day. He arrived back in Belgium with a different relationship to wine than he had left with. In 2008 he and Céline Haspeslagh, whose family had farmed the Belgian countryside for three centuries, visited Hermanus on South Africa's southern coast and found a valley that reminded him, in climate logic if not in landscape, of what he had seen in Spain: cold mornings, maritime air, a long growing season. They went home, lived their European lives, and for thirteen years the valley stayed in the back of the conversation. In 2021 they bought the estate and moved. Céline brought the farming inheritance; Frederik brought the Spanish memory. The wine they are most known for is a Pinot Noir from a river valley they first saw on holiday.

The Producer

Hasher Family Estate sits on the banks of the Onrus River in the Upper Hemel-en-Aarde Valley, a registered ward within the Walker Bay wine district near Hermanus. Three wines, three grapes, one valley: this is not a producer with range ambition or a sprawling portfolio. It is a focused estate built around what the Upper Hemel-en-Aarde does well in a cool Atlantic climate, and the lead wine, Ernest Pinot Noir, carries the editorial weight.

The estate was founded in 1997 and changed hands in 2021 when Belgian couple Frederik Herten and Céline Haspeslagh acquired and rebranded it, relocating permanently from Europe. Their winemaker, Natasha Williams, joined in 2023 after training in oenology at Stellenbosch University. She had started that degree in molecular biology before switching to wine in her second year. The scientific background shows in the approach: deliberate, precise in variety selection, quiet about noise.

Place

The Upper Hemel-en-Aarde Valley is a distinct registered ward within the broader Hemel-en-Aarde Valley, which is itself part of the Walker Bay district. The Upper ward sits higher and further inland than the valley floor, but the cold Benguela Current off the Atlantic keeps average temperatures low throughout the growing season. That cold air, funnelled through the valley by mountain topography, slows ripening and preserves acidity in all three grapes grown here.

For Pinot Noir and Chardonnay, the Walker Bay climate works like a bridge between what South Africa can do at warm inland sites and what a cool maritime region produces: tighter fruit, more mineral lift, lower alcohol potential, longer hang time on the vine. For Sauvignon Blanc, it delivers freshness over tropical weight. The appellation distinction matters on the label because it signals the sub-valley's specific temperature signature, not just a general Western Cape address.

Soil And Site

The vineyard soils at Hasher are clay over decomposed granite loam with quartzite inclusions. Clay retains moisture through dry periods and keeps vine stress moderate. Decomposed granite loam drains without stripping the vine of water entirely and contributes a mineral substrate. Quartzite inclusions reflect heat back onto the vine canopy during cooler evenings, a minor but measurable factor in ripening consistency in a cold-climate site.

This combination of water retention and drainage, alongside the well-structured mineral base, links directly to what appears in the glass: the Pinot Noir's density alongside the salinity note, the Chardonnay's textural weight paired with its acid-bright finish.

Story

Frederik Herten encountered wine in Spain, in the Ribera del Duero region, before he knew he would eventually farm it. That encounter planted something. In 2008 he and Céline Haspeslagh visited Hermanus, a coastal town on Walker Bay's western edge, and found a valley that held their attention in a way no inland South African site did: cool, maritime, geologically interesting, far enough from the equator to behave like a European wine region in terms of temperature curves.

They did not act immediately. They returned to Europe, and for over a decade Hermanus remained an idea. In 2021 they acquired the estate and moved permanently. Céline brought a different kind of continuity to the project. Her family had farmed in Belgium for three centuries, and that agricultural inheritance shaped how she understood the stewardship of land. The decision to rebrand around the family name was deliberate: this was not a property investment, but a farming commitment.

When Natasha Williams arrived as head winemaker in 2023, she brought her training in molecular biology and oenology from Stellenbosch University. Her switch from molecular biology to oenology mid-degree at Stellenbosch had given her both a cellular understanding of fermentation and a willingness to follow curiosity past the obvious path. The combination of a Belgian farming family and a South African scientist with an unusual training arc has produced a range of three wines built around terroir clarity rather than cellar intervention.

Vineyards And Cellar

Hasher farms Pinot Noir, Chardonnay, and Sauvignon Blanc on clay and decomposed granite soils in the Upper Hemel-en-Aarde Valley. The cool-climate farming philosophy means the priority is preserving what the site delivers naturally: freshness, defined fruit character, and acidity. Ripeness is not pushed.

The winemaking direction prioritises wines that reflect place. Barrel specifics for the Chardonnay remain unconfirmed in available sources, though the aromatic profile of toasted coconut alongside zesty acidity on the finish points to some oak influence used with a light hand. The Pinot Noir and Sauvignon Blanc profiles suggest cellar work that stays out of the way of the grape and the site.

Wines

Ernest Pinot Noir is the range anchor. The 2023 vintage received a 98-point score from the London Wine Competition. On the nose it offers strawberry, cherry, sour cherry, and pomegranate alongside garden herbs and a savoury underpinning. There is a distinct salinity note that is unusual in South African Pinot Noir and almost certainly connected to the maritime air of the valley. The palate is vibrantly dense with clear definition, and the tannins are fine-grained and integrated, giving the wine a long, refined finish.

Marimist Chardonnay opens with white pear, apricot, citrus blossom, and toasted coconut. The palate enters softly with generous texture and weight, then brightens on the finish with zesty acidity and lemon. The arc from creamy entry to bright finish gives the wine a broader range of temperature and food pairing than a purely mineral-driven Chardonnay would.

Nauticus Sauvignon Blanc is the most direct of the three. Gooseberry, capsicum, and hints of tropical fruit on the nose, pure and fresh in delivery. The finish is mineral and lingers cleanly. This is cool-climate Sauvignon Blanc that leads with the grape's natural fruit clarity rather than herbaceous sharpness.

In The Glass

The Ernest Pinot Noir opens with red fruit layered in two directions: the fresh and slightly sweet strawberry and cherry, and the tarter, more compressed sour cherry and pomegranate below. Garden herbs and a savoury underpinning lift from the glass alongside a salinity that reads as coastal rather than mineral, which is unusual for the variety in South Africa. In the mouth the wine is dense without being heavy, the fruit carried by tannins that are fine enough to disappear into the texture but present enough to give the finish its length and refinement.

The Chardonnay shows its textural character from the first moment: soft entry, generous mouthfeel, then a pivot at mid-palate where the acidity takes over and the finish brightens to lemon and zesty freshness. The Sauvignon Blanc stays in one lane, which is the right decision for the variety: clean, focused, mineral on the finish, with the gooseberry and capsicum character of a cool-climate growing season.

A Bottle To Understand It

Start with the Ernest Pinot Noir. It is the wine that most clearly states what the Upper Hemel-en-Aarde Valley and this estate are trying to do together. The salinity note, the sour cherry alongside the fresh red fruit, the fine tannin and long finish: these are not South African Pinot Noir characteristics you find often, and they trace directly to a cold Atlantic valley with clay and granite soils farmed without pushing ripeness. The 98-point London Wine Competition score for the 2023 is a useful external marker, but the bottle earns its place here on what it delivers in the glass, not the number.

Anecdote

Frederik Herten first encountered serious wine in Ribera del Duero, Spain's high-plateau red wine country, where the Tempranillo grows at altitude and the nights are cold enough to stop what the sun starts during the day. He arrived back in Belgium with a different relationship to wine than he had left with. In 2008 he and Céline Haspeslagh, whose family had farmed the Belgian countryside for three centuries, visited Hermanus on South Africa's southern coast and found a valley that reminded him, in climate logic if not in landscape, of the Spanish plateau: cold mornings, maritime air, a long growing season. They went home, lived their European lives, and for thirteen years the valley stayed in the back of the conversation. In 2021 they bought the estate and moved. Céline brought the farming inheritance; Frederik brought the Spanish memory. The wine they are most known for is a Pinot Noir from a river valley they first saw on holiday.

Final Word

Hasher Family Estate is a young producer in a serious South African cool-climate appellation, farming three varieties with focus and releasing wines that reflect the Upper Hemel-en-Aarde Valley without dressing it up. The Ernest Pinot Noir is the bottle to reach for first.
