The Godfather of Australian Organic Wine
Gil Wahlquist was a journalist — a jazz critic, a film reviewer, a newspaper editor. In 1971, he and his wife Vincie moved from Sydney to Mudgee, bought a patch of dirt in the foothills of the Great Dividing Range, and planted Australia's first certified organic vineyard. They rejected "clean cultivation" — the industry standard of bare earth and chemical sprays. They left weeds in place so pests would eat them instead of the vines. They refused DDT. When certification bodies were eventually created, Botobolar was the first to be certified. In 1984, they made their first preservative-free Shiraz — another Australian first. For decades, they were "the first and for many years the only Australian vineyard accredited by the National Association of Sustainable Agriculture." Gil was a tireless promoter — he established the Mudgee Wine Grape Growers Association, the Mudgee Wine Show, and the Mudgee Small Farms Field Days. He launched the Botobolar Bugle, "Australia's longest-running winery newsletter." He persuaded the NSW Department of Education to set up a viticulture course at Mudgee Technical College. In 1994, Kevin and Trina Karstrom bought the vineyard and carried the torch for another 25 years. Today, Botobolar continues as Australia's oldest certified organic wine company — a legacy of conviction, stubbornness, and the belief that wine should feel good to drink, to share, and to stand behind.
From the Newsroom to the Vineyard
Gil Wahlquist was born Eric Gilbert Wahlquist in Moonee Ponds, Melbourne, in 1927. His father was a theatre manager; his grandfather was a Swede who had jumped ship at Port Pirie and married into an Australian family of German descent. Gil developed an interest in journalism during high school, working on the school magazine. After serving in the Royal Australian Navy during WWII, he attended the University of Adelaide, edited the student newspaper On Dit, and married Vincie Porter in 1950. He worked at The News in Adelaide, then moved to Sydney in 1956 to join The Sydney Morning Herald. On the side, he reviewed jazz, folk and pop records for the Sun Herald.
In 1958, Gil took a position with TV Times in Sydney, where he worked for ten years. He developed a passion for sailing, built several boats, and helped found the Australian Sabot Sailing Association. He then moved into public relations with Nielsen McCarthy. But by 1971, something had shifted. Gil and Vincie, seeking a slower-paced lifestyle, moved to Mudgee in the Central West of New South Wales. They purchased land in the foothills of the Great Dividing Range and named it Botobolar Vineyard. Gil signed on as editor of the Mudgee Guardian — on a third of his Sydney salary — and launched the Botobolar Bugle, which would become "Australia's longest-running winery newsletter." Vincie worked as a teacher at Mudgee Public School.
The first vines were planted in 1971. In 1974, the grapes were ready — but the selling price was very low. Gil decided to make his own wine instead. He introduced innovations that would reshape Australian viticulture: he rejected "clean cultivation" (bare earth under vines, weeds removed), preferring to leave weeds in place so pests would eat them instead of the vines. He refused to spray DDT. He developed a system of farming without herbicides or pesticides, using only organically acceptable chemicals — winter oil, lime and sulphur mixtures, and sulphur dusting. He produced preservative-free wine. According to Huon Hooke, "Botobolar was the first and for many years the only Australian vineyard accredited by the National Association of Sustainable Agriculture." Gil became known as the "godfather of Australian organic wine."

Dryland, Organic & Stubbornly Independent
The Botobolar Vineyard sits in the foothills of the Great Dividing Range, north of Mudgee in the Central Ranges of New South Wales. The property spans 22 hectares, all dryland — no irrigation. The vines have always been tended without pesticides, herbicides, or chemical fertilisers. The soil is sustained and nourished through organic practices: composting, cover cropping, and working in harmony with the surrounding ecosystem. Hand picking and pruning are standard. The philosophy is simple: cultivate grapes in harmony with nature, and the wine will follow.
The vineyard was always dryland, which made it vulnerable. Continual droughts throughout the Karstroms' tenure — culminating in the brutal dry period of 2015–2018 — saw much of the original vineyard die. To meet growing demand for organic wine, the Karstroms sourced fruit from other certified organic growers, including Windowrie Estate in Canowindra. Health issues and drought eventually forced Kevin and Trina to sell the property and retire after 25 years in 2018. But the brand lived on. They teamed up with Jason O'Dea from Windowrie and winemaker Anthony D'Onise to continue producing their flagship Preservative Free Shiraz and the broader Botobolar range.
Today, Botobolar continues as Australia's oldest certified organic wine company. The wines are certified by ACO (Australian Certified Organic). The range spans Shiraz, Cabernet Sauvignon, Chardonnay, Marsanne, Verdelho, and preservative-free expressions. The winemaking remains minimal input — no preservatives, no animal-based products, no fining agents. The intention is always to bottle the most natural product possible. The vineyard may have changed hands, but the philosophy remains exactly what Gil Wahlquist established in 1971: organic, honest, and uncompromising.
The vineyard spans 22 hectares in the foothills of the Great Dividing Range, north of Mudgee. All dryland — no irrigation. The vines rely entirely on rainfall and deep root systems. This makes the vineyard vulnerable to drought but also forces the vines to produce fruit of remarkable concentration and character.
Organic from day one — 1971. When certification bodies were eventually created, Botobolar was the first vineyard to be certified organic in Australia. Certified by ACO (Australian Certified Organic). No pesticides, no herbicides, no chemical fertilisers. Weeds left in place; pests eat the weeds, not the vines.
Botobolar crafted its first preservative-free Shiraz in 1984 — one of Australia's earliest. No added sulphur dioxide, no preservatives of any kind. The wines are made without animal-based products, without fining agents, without filtration. The intention is always to bottle the most natural product possible.
Kevin and Trina Karstrom purchased Botobolar in 1994 and carried the organic torch for 25 years. They raised their children on the organic property and expanded the range. After drought and health issues forced their retirement in 2018, they partnered with Jason O'Dea of Windowrie Estate and winemaker Anthony D'Onise to continue the Botobolar legacy.
Minimal Input, Maximum Integrity
Botobolar's winemaking philosophy has remained remarkably consistent for over five decades: minimal input, maximum integrity. The grapes are grown organically — no synthetic chemicals, no irrigation, no shortcuts. In the winery, the approach is equally restrained. The Shiraz is crushed and de-stemmed, then transferred to small stainless open fermenters. The cap is plunged by hand three times a day. The wine is pressed off the skins at the three-quarter mark of fermentation to maximise extraction while avoiding over-extraction from the large berries typical of dryland vines.
The use of any preservatives or animal-based products is avoided during production. No sulphur dioxide, no egg whites, no gelatin, no isinglass. The intention is to bottle the most natural product possible. For the Shiraz, a moderate amount of both French and American oak is used — enough to add structure and complexity without masking the fruit. The Cabernet Sauvignon is known for its chocolate and mint character — a signature of the Mudgee terroir. The Chardonnay is made from the Busby clone, one of Australia's heritage clones. The Marsanne and Verdelho add aromatic white options to the range.
This is not natural wine in the trendy, lo-fi sense. This is organic wine in the original sense — wine made from grapes grown without chemicals, processed without additives, and bottled without preservatives. Long before "natural wine" became a hashtag, Botobolar was doing exactly this. The difference is that Botobolar never made a fuss about it. The Wahlquists and the Karstroms simply believed it was the right way to farm and the right way to make wine. That quiet conviction is what makes Botobolar one of the most important wineries in Australian history.
The Botobolar Bugle — Australia's Longest-Running Winery Newsletter
When Gil Wahlquist moved to Mudgee in 1971, he didn't just plant vines — he planted ideas. The Botobolar Bugle was his winery newsletter, and it became "Australia's longest-running winery newsletter." Through its pages, Gil educated consumers, challenged conventions, and built a community around organic wine long before anyone else was talking about it. He wrote about sustainable agriculture, criticised chemical farming, and promoted the Mudgee region with tireless energy. The Bugle was more than marketing — it was manifesto, education, and community-building all in one. Gil also established the Mudgee Wine Grape Growers Association, the Mudgee Wine Show, and the Mudgee Small Farms Field Days. He persuaded the NSW Department of Education to set up a six-month viticulture course at Mudgee Technical College in 1974. This was not a winemaker making wine; this was a movement-builder creating culture.
A Quiet Revolution That Changed Everything
Gil Wahlquist died on 7 December 2012, aged 85. The tributes poured in from across the Australian wine industry. Huon Hooke called him "a pioneer organic wine producer" and "an innovator in organic wine." His daughter Åsa Wahlquist, a respected wine writer, wrote in The Sydney Morning Herald: "Words, wine and wisdom." The sign at the entrance to Botobolar — "Trespassers will be Composted" — summed up his humour, his conviction, and his deep belief in the cyclical nature of farming. He was the godfather of Australian organic viticulture, and his influence extends far beyond the 22 hectares of Botobolar.
The legacy is tangible. Botobolar inspired a generation of Australian organic and biodynamic growers — from Castagna in Beechworth to Cullen in Margaret River, from Jasper Hill in Heathcote to Lowe Wines in Mudgee itself. David Lowe, another Mudgee organic pioneer, was named the inaugural Legend of the Vine by Wine Communicators of Australia in 2014. The Mudgee region, once a fading wine area, is now celebrated for its organic wines, its close-knit community, and its commitment to sustainable innovation. Much of that traces back to one journalist who decided to plant vines in 1971 and do things differently.
Today, Botobolar continues under new stewardship — the partnership with Windowrie Estate and winemaker Anthony D'Onise ensures that the preservative-free Shiraz and the broader organic range remain available. The brand is now based in Pacific Palms on the NSW Mid North Coast, with a cellar door open Monday to Friday. The wines are sold through organic wine specialists, online, and at select retailers. The vineyard in Mudgee may no longer be under the Botobolar name, but the philosophy — organic, preservative-free, minimal input — lives on. As the website says: "We believe wine should feel good — to drink, to share, and to stand behind."
