The Cosmic Farm & the Fraternal Hand
Finca Cosmos is a biodynamic family farm and artisanal natural winery in Villa Tulumaya, Lavalle, in the desert north of Mendoza — a four-hectare universe where Laura Manzano and her family have spent more than twenty years cultivating a radical alternative to industrial agriculture. On just two hectares of vines — old parrals of Pedro Giménez, Torrontés Sanjuanino, Criolla and Bonarda — they produce a mere 10,000 litres per year of zero-sulfite, unfiltered, unfined natural wine in a mud-built cellar, using recycled bottles and natural wax capsules made by hand on the farm. Certified through a participatory biodynamic system (SPG) since 2020, Finca Cosmos is a self-sufficient organism of medicinal herbs, fruit trees, flowers, vegetables, farm animals, natural cosmetics, juices, preserves and a cow named Melisa whose portrait graces the label of their most iconic wine. This is not a winery that happens to have a farm; it is a farm that happens to make wine — guided by the lunar calendar, a fraternal economy, and a conviction that the value of labour matters more than the weight of raw materials.
Laura Manzano & the Biodynamic Hand
The story of Finca Cosmos begins with Laura Manzano and a family conviction that agriculture should heal rather than exploit. For more than twenty years, the Manzano family has worked the land in Villa Tulumaya — a small settlement in the northern reaches of Mendoza province, where the Andean foothills give way to high desert and the conventional wine industry rarely ventures. What began as a modest aspiration to produce healthy food for people and for the earth gradually evolved into one of the most authentic biodynamic projects in Argentina — a diversified farm where wine is simply one expression of a broader ecological commitment.
Unlike the grand estates of the Uco Valley or the historic bodegas of Luján de Cuyo, Finca Cosmos operates at a human scale. The entire property spans only four hectares, of which two are planted to vines — the rest given over to medicinal and aromatic herbs, fruit trees, flowers, vegetables, and farm animals. The family lives on the land, works the land, and sells the products of the land through a fraternal economy that prioritises the value of labour over the market price of raw materials. This is not a commercial strategy but a moral one: a refusal to participate in the extractive logic of industrial agriculture, and a commitment to building a local, circular, regenerative economy that sustains both the soil and the people who tend it.
In 2020, Finca Cosmos formalised its biodynamic credentials by entering a participatory certification system (SPG) among farmers — becoming the first estate in Argentina to receive Biodynamic Agriculture certification through this grassroots, peer-to-peer model. The certification is not a corporate badge but a community contract: farmers inspect one another's practices, share knowledge, and hold each other accountable to the standards of Rudolf Steiner's agricultural impulse. For the Manzano family, this participatory approach mirrors the fraternal economy of the farm itself — wine, food, cosmetics and community woven into a single fabric of mutual support. The winery, built by hand from mud and adobe, is a physical manifestation of this philosophy: no concrete monolith, no stainless-steel cathedral, but a humble, earthen cellar where the wines are born in quiet dialogue with the land.
"El objetivo de esta familia es crear vinos que reflejen su esencia, en perfecta armonía con la naturaleza."

Villa Tulumaya & the Lavalle Desert
The estate is located in Villa Tulumaya, in the department of Lavalle, roughly 40 kilometres north of the city of Mendoza — a region far removed from the glamorous wine routes of the Uco Valley and the Maipú tourist circuit. Lavalle is high desert: intensely sunny, extremely dry, with sandy and clay-loam soils that have never known the chemical saturation of industrial monoculture. The climate is continental and arid, with scorching days, cold nights, and a relentless mountain wind that sweeps down from the Andes, keeping the vines healthy and reducing disease pressure to the point where synthetic treatments are not merely avoided but unnecessary.
The soils of Finca Cosmos are franco-arcilloso — clay-loam in texture — with a living ground cover of native grasses and herbs that the family cultivates deliberately rather than suppressing. This is not the poor, stony alluvium of Gualtallary or the calcareous limestone of Altamira; it is a generous, fertile earth that retains moisture and supports biodiversity, but one that demands careful stewardship to prevent compaction and erosion. The family employs manual weeding rather than herbicides, and rotational sheep grazing during autumn and winter to enrich the soil naturally with manure and control ground cover without machinery. The result is a vineyard that is indistinguishable from the surrounding farm — vines, herbs, flowers and animals coexisting in a single, integrated organism.
The vineyard itself is planted to traditional Argentine varieties that have fallen out of favour in the industrial wine sector: Pedro Giménez, Torrontés Sanjuanino, Criolla Grande, Criolla Chica, Criolla Cereza and Bonarda, with a tiny parcel of Syrah that was originally planted as a perimeter hedge and now produces one of the estate's most sought-after wines. The vines are trained in the old parral style — high pergolas that cast dappled shade, require hand-harvesting, and produce small quantities of concentrated fruit. Some of the Criolla vines are over 50 years old; the Bonarda parcel is 15 years old and already displays the deep root penetration and thick skins that come with maturity. Irrigation is conventional furrow or drip, using water from the Andean snowmelt that is the lifeblood of all Mendoza viticulture, but applied with restraint and observation rather than automation.
Finca Cosmos is based in Villa Tulumaya, a small rural settlement in the department of Lavalle, north of Mendoza city. The region is accessible from the capital but feels worlds away from the industrial wine corridors of the south. The landscape is one of high desert, ancient alluvial plains, and small family farms that have resisted the encroachment of large-scale agriculture. While much of Mendoza pursues volume and global export, Lavalle offers something rarer: a microclimate of small-scale, intensively biodiverse farms where biodynamic principles can be applied with precision and observed with patience. The estate is a living organism rather than a production unit, and the wines reflect this integrated, holistic approach to agriculture.
The Finca Cosmos terroir is defined by franco-arcilloso soils — a clay-loam matrix that is fertile, moisture-retentive and rich in organic matter compared to the stony alluvium of the Uco Valley. The family maintains a living ground cover of native grasses and herbs throughout the vineyard, preventing erosion, fostering microbial life, and creating habitat for beneficial insects. Manual weeding replaces herbicides; rotational sheep grazing replaces tractors. This soil management produces vines that are healthy, balanced and naturally resistant to stress, yielding grapes of surprising concentration and aromatic complexity despite the modest scale of the farm. The clay component provides structure and mineral depth, while the loam ensures that the roots have access to water and nutrients without excessive irrigation.
Finca Cosmos has been farmed biodynamically for over two decades and in 2020 became the first estate in Argentina to receive Biodynamic Agriculture certification through a participatory system (SPG) among farmers. This grassroots model replaces the conventional top-down audit with a peer-to-peer network in which farmers inspect one another's practices, share biodynamic preparations, and collectively uphold the standards of Rudolf Steiner's agricultural philosophy. The farm employs biodynamic preparations — including cow-horn manure, horn silica, and herbal composts of chamomile, yarrow, nettle and dandelion — applied according to the lunar calendar on root days, leaf days, flower days and fruit days. The result is a self-regulating ecosystem where the vines, the soil, and the native flora of the Lavalle desert coexist in a productive, regenerative harmony.
The vineyard is planted to traditional Argentine varieties in the old parral style — high pergolas that require hand-harvesting and manual labour. The Criolla vines are over 50 years old, producing tiny quantities of thick-skinned, concentrated fruit with a natural resistance to oxidation that makes them ideal for zero-sulfite winemaking. The Bonarda parcel, at 15 years, is mature enough to express deep root penetration and mineral complexity. Pedro Giménez and Torrontés Sanjuanino — varieties rarely treated with serious intent in modern Mendoza — are farmed with the same care as the reds, producing whites and oranges of extraordinary texture and aromatic intensity. The Syrah parcel, originally a perimeter hedge, has become the source of the estate's most iconic micro-cuvée. These are not commercial varieties chosen for market appeal; they are the patrimony of the place, preserved by a family who values genetic diversity over homogeneity.
Mud, Moon & the Zero-Input Hand
The cellar philosophy of Finca Cosmos is one of absolute non-intervention and total transparency. All wines are made in a small artisanal winery built by hand from mud and adobe — a structure that breathes, regulates temperature naturally, and embodies the estate's refusal of industrial aesthetics. Fermentation is spontaneous, using only indigenous yeasts present on the grape skins and in the vineyard environment. No selected yeasts, no enzymes, no commercial additives, no sulfites at any stage — the wines are bottled as they are born, without fining, without filtration, without cosmetic correction. The family believes that the health of the biodynamic fruit and the cleanliness of the earthen cellar provide all the stability that natural wine requires.
Winemaker Raimundo Laugero orchestrates the cellar with a light but attentive hand, respecting the rhythms of the moon and the pulse of the earth. The La Mocha Naranjo — an orange wine from Pedro Giménez — ferments on its skins for one month following lunar rhythms, then ages in used barrels before bottling without clarification or filtration. The La Mocha Bonarda is fermented with 25% whole clusters and 75% destemmed fruit in plastic enological tanks, capturing the juicy, rustic soul of the variety without oak interference. The En Ojotas rosado is made from 50% whole-cluster and 50% destemmed Criolla, macerated on skins for nine months in tanks, then bottled with 4 grams per litre of residual sugar to provoke a gentle, natural re-fermentation in the bottle — a delicate, rustic fizz that evokes the farm's casual, barefoot spirit.
Sustainability extends beyond the cellar to the bottle itself. Finca Cosmos uses recycled glass bottles and natural wax capsules produced by hand on the farm — a labour-intensive choice that eliminates synthetic closures and industrial packaging. The labels are simple, often featuring the animals of the farm: Melisa the cow graces the Postales de Cosmos Syrah, while La Mocha the sheep — who lost an ear in a youthful attempt to escape the pasture — lends her rebellious name to the Bonarda and orange-wine lines. These are not marketing mascots but members of the farm's biological community, honoured as co-producers of the wine's terroir. The result is a range of wines that are cloudy, alive, deeply individual and unmistakably honest — each bottle a document of a specific lunar cycle, a specific manual harvest, and a specific refusal to compromise.
Indigenous Yeasts, Lunar Rhythms & the Zero-Sulfite Rule
The guiding principle of Finca Cosmos is that the wine must be a mirror of the biodynamic farm and the lunar rhythms that govern it. The participatory biodynamic farming provides healthy, complex grapes that are naturally balanced and resistant to oxidation. The hand harvest provides pristine, intact fruit. The spontaneous fermentation with indigenous yeasts provides a microbial fingerprint that is unique to the clay-loam soils of Villa Tulumaya. The absence of additives, selected yeasts, sulfites, fining and filtration ensures that the wine is a product of the vineyard and the earthen cellar, not the laboratory. The nine-month skin maceration for En Ojotas, the one-month lunar fermentation for La Mocha Naranjo, and the whole-cluster inclusion for La Mocha Bonarda provide textures and aromatics that industrial protocols could never achieve. And the recycled bottles and hand-made natural wax capsules provide a packaging philosophy that extends the farm's zero-waste ethos to the consumer's table. The cellar is not a factory; it is a continuation of the mud-built farm — a place where patience, lunar observation, and the refusal to standardise translate biodynamic fruit into wine that is living, rustic, and unmistakably of its place.
En Ojotas, La Mocha & the Postales Hand
Finca Cosmos produces approximately 10,000 litres per year — a tiny output even by Argentine natural-wine standards — across a tightly curated portfolio of zero-sulfite, unfiltered, unfined wines that express the farm's traditional varieties and biodynamic philosophy. The range is built around Pedro Giménez, Criolla, Bonarda and Syrah, with each cuvée named after an element of the farm's daily life: the flip-flops (ojotas) worn while walking the rows, the rebellious sheep (Mocha) who lost an ear escaping the pasture, and the postcards (postales) written from the land to the glass. All wines are hand-harvested, spontaneously fermented with indigenous yeasts, bottled without fining or filtration, and sealed with natural wax capsules made on the farm. Production is minute; the Postales de Cosmos Syrah numbers only 400 bottles, and even the larger cuvées are counted in the low thousands. These are wines that cannot be scaled, cannot be replicated, and cannot be separated from the farm that produces them.
The Fraternal Economy & the Mud-Built Hand
Finca Cosmos is not merely a winery; it is a proof that a family of four hectares, armed with a mud-built cellar, a herd of sheep, and a refusal to add a single molecule of sulfur to their wine, can produce bottles that challenge the hierarchy of Argentine viticulture while nourishing the land and the community that tends it. In an era when Mendoza is dominated by industrial scale, globalised palates, and the relentless pursuit of export volume, the Manzano family has demonstrated that the same Lavalle clay-loam can produce wines that are cloudy rather than polished, rustic rather than refined, and zero-sulfite rather than chemically preserved — if the farming is biodynamic, the cellar is a place of absolute non-intervention, and the philosophy is one of fraternal economy rather than commercial ambition.
The legacy of Finca Cosmos is the legacy of the participatory hand applied to viticulture. The SPG certification is not a bureaucratic achievement but a community contract — a network of farmers who inspect one another's compost pits, share horn manure preparations, and collectively uphold a standard of agriculture that treats the farm as a living organism. The recycled bottles and hand-made wax capsules are not marketing gestures but extensions of the farm's zero-waste ethos — a refusal to import industrial packaging that contradicts the land's regenerative logic. And Melisa the cow, La Mocha the sheep, and the old Criolla parral are not agricultural curiosities but co-producers of the wine's terroir — living partners in a system where animals, vines, herbs and humans share a single biological destiny.
The future of the project is tied to the future of the Lavalle desert as a sanctuary for small-scale, biodiverse agriculture in a region increasingly pressured by monoculture and water extraction. As the 50-year-old Criolla vines accumulate another year of root depth in the clay-loam, as the Postales de Cosmos Syrah finds its audience among natural wine drinkers from Buenos Aires to Berlin, and as the En Ojotas frizzante proves that a nine-month skin-macerated Criolla can be both stable and joyful, Finca Cosmos remains what it has always intended to be: a four-hectare universe where wine, food, cosmetics and community are woven into a single fabric of biodynamic harmony — a farm that makes wine not for the market, but for the earth. The story of Finca Cosmos is the story of a family who looked at a patch of high desert and saw not emptiness, but a cosmos — and who proved that the best bottle from Mendoza is the one that needs no chemical explanation, only a glass, a meal, and the patience to let the Villa Tulumaya soil speak.
