Wine as It's Meant to Be
Coturri Winery is a living piece of California wine history — a third-generation, family-run natural wine estate on Sonoma Mountain above Glen Ellen, in the heart of the Valley of the Moon. [^2^] [^8^] Founded in 1979 by Harry "Red" Coturri and his sons Tony and Phil, the winery has been making wine since 1963 with a philosophy so pure it fits on a single label: "Just Grapes." [^5^] [^8^] Tony Coturri, now the custodian of the family legacy, has never added sulfites, never used commercial yeasts, and never compromised on the belief that wine should be a true expression of terroir — alive, honest, and unmanipulated. [^2^] [^9^]
From Farneta, Italy to Sonoma Mountain
The Coturri story begins in the village of Farneta, Italy, where Enrico Coturri immigrated to America in 1901 with $10 in his pocket. [^5^] He settled in San Francisco, worked as a barrel cooper, and helped rebuild the city after the 1906 earthquake. [^1^] Enrico taught his son Harry "Red" Coturri the Italian winemaking methods he had brought from the old country — techniques rooted in patience, intuition, and respect for the grape. [^5^] Red began making wine during Prohibition and the Great Depression, a tradition of necessity that became a philosophy of life.
In 1961, the Coturri family acquired land on Sonoma Mountain above Glen Ellen — a wild, rugged hillside in what would become the Valley of the Moon. [^9^] They planted their first two acres of Zinfandel in 1967, adding another five acres in 1975. [^2^] In 1979, Red founded Coturri Winery with his sons Tony and Phil, making them among the very first pioneers of what we now call the natural wine movement in California. [^2^] [^5^] The timing was radical: post-war industrial agriculture had made pesticides, fungicides, and synthetic fertilisers the norm, but the Coturris recognised that these chemicals were damaging the land and the people who worked it. [^2^]
Tony Coturri has been making wine since 1964, and from the very first vintage, the family refused to use RoundUp, pesticides, or sulfites. [^9^] "It's been 39 years of doing it," Tony told Sprudge in 2018, though that number has since doubled. [^9^] The early years were isolating. Tony was a young man on an island — more likely to find like-minded farmers in the nut and fruit industries than among fellow winemakers. [^9^] When he tried to talk about natural yeast and zero sulfites, wine shops were afraid the bottles would explode and "spew biological contamination." [^9^] Robert Parker, improbably, became one of his earliest champions, but the broader wine world took decades to catch up.
Today, Tony is the custodian of the Coturri legacy, teaching his son Nic the craft while remaining true to the methods of his grandfather Enrico and father Red. [^1^] The winery sits above Glen Ellen on Sonoma Mountain, surrounded by head-pruned, dry-farmed Zinfandel vines that have grown alongside Tony for more than 50 years. [^2^] It is a place where time moves slowly, where the wines are allowed to age for decades, and where the only ingredient that matters is the grape itself.
"Natural wine is living wine. Field yeasts are the umbilical cord from the vine to the glass, transmitting a sense of place to the wine, and commercial yeasts cut this vital connection. SO2 kills terroir. Natural wines are movies of the vineyard and vintage; a story full blown and alive."
— Tony Coturri
Dry-Farmed, Head-Pruned & Zero Additions
Coturri Winery's production is defined by radical simplicity: just grapes, pure and simple. [^5^] The estate vineyard is dry-farmed and head-pruned in the traditional Italian goblet style — an ancient technique that forces vines to dig deep for water, concentrating flavour and building resilience. [^5^] The vines are never treated with pesticides, fungicides, or herbicides. [^5^] Grapes are picked at peak ripeness by hand and fermented with indigenous yeasts. No sulfites are added at any point during vinification. The wines are neither fined nor filtered. No additions or manipulations of any kind are made. [^5^]
This is not a marketing stance — it is a 60-year practice. Tony believes that the grapes will speak to you if you listen. His job, as he puts it, is simply to "listen to the vines and stay the hell out of the way." [^2^] Throughout the years, he has resisted bending to trends, making wine according to the latitude of the region and using his experience, intuition, and taste to create wines that are the fullest expression of their terroir. [^2^] The result is a portfolio that balances the liveliness of natural wine with the ripeness of classic California — juicy, fruity, and deeply expressive, with the ability to appeal to both ardent natty crushers and those who have never heard the word "biodynamics." [^9^]
The Coturri approach extends beyond the winery. Tony's brother Phil Coturri — through Enterprise Vineyards — has become one of the most influential organic and biodynamic vineyard managers in California, farming over 700 acres across Sonoma and beyond for clients including Kamen Wines, Mayacamas Vineyards, and Bedrock Wine Co. [^3^] [^6^] Phil helped establish the Moon Mountain District AVA in 2013 and has been recognised by Congress for his 60 harvests of organic stewardship. [^3^] Together, the Coturri brothers have shaped not just their own wines but the entire landscape of California natural wine.
The wines are aged in oak barrels — used, neutral vessels that impart no oak flavour, allowing the fruit and terroir to speak without mask or manipulation. [^5^] This combination of ancient Italian technique, California terroir, and uncompromising natural philosophy defines the Coturri aesthetic: rooted in history, resistant to fashion, and utterly committed to the living, evolving nature of wine.
No SO2 added at any point — not at harvest, not at bottling, not ever. [^5^] Tony believes sulfites kill terroir, hinder positive microbial development, and reduce wine to a "single frame" rather than the full movie of a vineyard and vintage. [^2^]
"Field yeasts are the umbilical cord from the vine to the glass." [^2^] Commercial yeasts cut this vital connection. Every Coturri wine is fermented with the natural yeasts present on the grape skins — a living link between vineyard and glass.
Estate Zinfandel vines planted in 1974, dry-farmed and head-pruned in the traditional Italian goblet style. [^2^] No irrigation, no chemicals, no shortcuts. Vines that have grown alongside Tony for over 50 years.
Certified organic by CCOF. Grapes sourced from organic or sustainable vineyards at minimum. [^1^] No glyphosate, no synthetic inputs. A 60-year commitment to clean farming and honest winemaking.
The First Wave of California Natural Wine
Tony Coturri is often described as a "reclusive star" of the natural wine world — a man who has been making the wines that today's natty bars pour before most of their drinkers were born. [^9^] His story is frequently skimmed over in the standard narratives of natural wine history: either the ancient Georgian origin story or the 1970s French vigneron revival. But the Coturri family was there from the beginning, planting and fermenting and refusing chemicals while the rest of California was embracing industrial agriculture. [^9^]
The early decades were a test of conviction. In the 1980s and 1990s, there was no natural wine scene — no Punchdown, no Ordinaire, no global community of like-minded drinkers. [^9^] Tony learned quickly that you couldn't walk into a shop and start talking about natural yeast and zero sulfites. "You had to just kind of talk about what everybody else talked about. 'Oh, the vineyard, and the clay…' and then when you finally made the sale, you said, 'Oh, by the way — an added benefit of this wine is there's no sulfites added and it's made with natural yeast.' People go, 'What?' It was like I was considered just out of my mind, radical." [^9^]
The Coturri wines are distinctive for their longevity. Because they are made without sulfites and with minimal intervention, they evolve in the bottle for decades — a master class in what can happen if you age a sans soufre wine with care. [^9^] They have the liveliness of natural wine with the ripeness of classic California, a combination that allows them to bridge worlds: appealing to both the committed natural wine drinker and the conventional wine lover who simply wants something honest and delicious. [^9^]
Today, Coturri is a bonafide star of the global natural wine community — listed on Raisin, the natural wine discovery app, and distributed through natural wine retailers from New York to Tokyo. [^5^] But the winery remains by appointment only, intimate and uncommercial, a place where Tony still makes wine the way his grandfather Enrico taught his father Red, the way Red taught Tony, and the way Tony is now teaching his son Nic. [^8^] The future of Coturri is rooted in the same principles that have defined it since 1963: just grapes, nothing more and nothing less.
Estate Zinfandel 2023 — 50-Year-Old Vines, Red Fruit & Earth
"Planted in 1974 on Sonoma Mountain, when Tony Coturri was just 23 years old, these head-pruned, dry-farmed vines have grown up alongside him. Now more than 50 years old, they produce what is widely considered the pride of Coturri Wines." [^2^] The cool 2023 vintage brought a longer growing season and a later harvest, allowing the fruit extended hang time to develop depth while retaining freshness. The result is a beautifully balanced Zinfandel with red fruit, bramble, and earthy undertones — honest, expressive, and rooted in place. This is Sonoma Mountain Zinfandel exactly as it should be: made without sulfites, without commercial yeast, without manipulation of any kind. A wine that proves natural wine can be both radical and timeless. ~$49.
