The Economist, the Colour Conversation & the Martians in the Vineyard
A Basque fisherman’s son who studied economics in Bilbao, taught himself oenology from a textbook, made a "Super Tempranillo" with every additive known to man, and then — after asking his oenologist relative why his wine had less colour — had a revelation that changed everything. Alfredo Maestro now makes ~115,000 bottles a year across 13 labels, from 115-year-old vines at 1,200 metres, with zero additives, zero new oak, and labels drawn by his son's friend that feature Little Red Riding Hood kissing the wolf.
Origin — The Fisherman's Son, the Textbook, and the Colour That Wasn't There
Alfredo Maestro Tejero was born in Peñafiel, a town in the heart of Ribera del Duero, but his family were not winemakers. They were fishermen from the Basque Country who had settled in Castilla y León. "Neither my father nor my extended family have any relation to wine," Alfredo says. "My family were actually fishermen, and at the age of 30 I was still living in the Basque Country, in Bilbao." He had studied Economics there, worked in finance, and had no intention of becoming a vigneron. Wine was a passion, not a profession.
But he had grown up among the vines of Ribera del Duero. He had watched the old growers work their farms, and the rhythms of the vineyard had imprinted on him. In the late 1990s, visiting friends in Madrid, he attended a wine tasting. It lit a flame. In 1998, at the back of his father's house in Peñafiel, he planted his first vineyard — Almate, an acronym for Al-fredo Ma-estro — on the banks of the Río Duratón. He planted Tempranillo, Merlot, and Cabernet Sauvignon, and set about making wine by the only method he knew: the textbook.
For the first few years, Alfredo made wine exactly as modern oenology dictated. He used cultured yeasts, tartaric acid, enzymes, tannins, colour-enhancers — every trick in the book to produce a "correct" Ribera del Duero: dark, extracted, oak-aged, purple. He even made a "Super Tempranillo" in the international style. But something nagged at him. He asked a relative — "someone in my family is a really important oenologist in Ribera del Duero" — why his wine had less colour than the commercial wines. The answer stopped him cold: "Alfredo, it's because we add colour to our wines."
"This answer made me think: why does there need to be so much added? The soil and the grapes become lost, and the wines are no longer really about the grape or the vintage." In the early 2000s, he began eliminating exogenous products. By 2003, he was making wine without any additives whatsoever — including sulfur for all but a few cuvées. The "Super Tempranillo" was abandoned. The real Alfredo Maestro was born.
Then the old vineyards started finding him. An elderly man in Peñafiel, too old to maintain his vines, offered Alfredo his plot. Then another. Then another. "Year on year, people say to me: 'Alfredo, this vineyard is for you!' because the owners and growers are getting very old." In 2012, his doctor inherited a vineyard in the Sierra de Gredos and asked for help. Alfredo went, fell in love with the 1,200-metre granite slopes, and came home with five Gredos vineyards. In eight years, his production increased 20-fold.
The Place — The Meseta, the Three Soils & the 115-Year-Old Vines
Alfredo works across a staggering geographic range for a single producer: ~45 hectares in total, of which roughly 9 hectares are vinified under his own labels, spread across Ribera del Duero, Cigales, Sierra de Gredos, and Navalcarnero (southwest of Madrid). He maintains two small bodegas — one in his native Peñafiel, where his father helps with the work, and another in Navalcarnero. The rest of the fruit is sold to other producers. His holdings are a patchwork of rescued parcels, many abandoned for years, others worked chemically until the owners grew too old to continue.
Three Soils of the Duero
In Ribera del Duero, Alfredo identifies three main soil types. At the bottom of the valley: alluvial soils, producing finer, more elegant wines with higher acidity. In the hills: clay, giving structure and ageing potential. At the top: limestone and calcareous soils, also high in acidity thanks to elevation. His vineyards span all three, from the valley floor to the mountain crest, allowing him to blend or bottle according to character rather than appellation.
30 to 115-Year-Old Vines
The vineyards range from 15-year-old plantings to 115-year-old bush vines. The oldest are treasure troves of pre-clone genetic material — Tempranillo grapes "similar in size to my hand", Alfredo says, compared to modern clone berries "similar to a 1L bottle of water." He estimates his holdings are roughly 25% old vines and 75% younger — the old vines for perfume and minerality, the young ones for freshness and immediate drinking.
700 to 1,200 Metres
Altitude is everything. The Peñafiel vineyards sit at 700-1,000 metres. The Sierra de Gredos parcels reach 1,000-1,200 metres on decomposed granite. The Navalcarnero plots and the Valtiendas vineyards (Segovia) sit at around 1,000 metres. Even the experimental Pinot Noir for his sparkling wine grows at 300 metres on limestone in Castellón, near the Mediterranean. The common thread: high elevation, poor soils, old vines.
Organic, Biodynamic & Self-Recuperating
Alfredo has farmed organically from the beginning and applies biodynamic principles across the estate. Many of the abandoned vineyards he takes over were chemically farmed for decades, but the years of neglect had an unexpected benefit: "The positive thing was that, since most vineyards were abandoned, the soils had started to recuperate themselves." It still takes 2-4 years of active restoration before the soils are healthy enough to express themselves. Horses and donkeys plough the narrow old-vine rows where tractors cannot fit.
Winemaking — Grapes. Fermentation. And That's It.
Alfredo's cellar philosophy can be expressed in three words: grapes, fermentation, wine. "I explained it: 'Grapes. Fermentation. And that's it, that is the wine.' To which they replied: 'Ah, but of course, you make natural wine.' I shrug. 'But I don't know or make "natural wines", this is just my normal wine.'" He never uses the term on his labels or for marketing. "For me, the most important thing is that the wine must be high quality. And after that, if it's also natural, then that's great. But the first requirement must be that the wine is high quality. Always."
All grapes are hand-harvested and hand-sorted. The decision to de-stem or include stems is made vintage by vintage, tank by tank, according to humidity, dryness, and acidity. "We only do punch downs, no pump overs. We do battonage and pigeage every day, except for the white and rosé." The rosé is always direct-pressed. The whites always see about one week of skin contact. The reds macerate for 15-20 days (longer for single-vineyard wines), with stem inclusion varying from 50-100% for Viña Almate depending on the year, to some or all stems for El Marciano.
Ageing happens in used barrels ranging from 225 to 500 litres — never new oak. "I don't like oak, it's not from the grape, not from the soil," he says, echoing Goyo García Viadero's identical sentiment. The used barrels provide slow oxidation and texture without masking the fruit. Most wines are bottled unfined and unfiltered. Sulfur is zero for most cuvées, with only tiny additions for a few single-vineyard reds (La Olmera, La Guindalera, Castrillo de Duero).
Alfredo's approach is intuitive and adaptive. He maintains a mix of varieties in different tanks so he can blend for balance — one tank may have screaming acidity from a high-altitude parcel, another may be more moderate. He waits, tastes, adjusts. "To me, wine is always a reflection of place. One tank may have very high acidity due to the area the grapes come from. Sometimes, I have to wait for a tank with less acidity to finish fermenting so that I can create more balance in the finished wine."
The Wines — Thirteen Labels, Thirteen Stories
Alfredo makes roughly 13 cuvées across four distinct geographic areas, each with its own label, its own story, and its own personality. Production totals around 115,000 bottles annually — large for a natural wine producer, but still tiny in the context of Ribera del Duero. All wines are bottled as Vino de la Tierra de Castilla y León or table wine, outside the DOs, because Alfredo refuses to limit himself to the permitted varieties and techniques.
Viña Almate
Entry red — Ribera del DueroThe original — named for Alfredo himself (Al-fredo Ma-estro). Sourced from various plots of Tinto Fino (Tempranillo) at 700-1,000 metres in Peñafiel and Valtiendas. Vine age varies from young to old. Fermented in steel vat with 15-20 days of maceration and 50-100% stem inclusion depending on vintage. Raised over winter with one racking. Unfined, unfiltered, no added SO₂. The wine that started it all — fresh, spicy, honest, and unmistakably Duero. Around 20,000 bottles. The best-value natural Tempranillo in Spain.
Lovamor
Skin-contact white — Ribera del DueroThe name is a contraction of "love" and "wolf" — lov and lovo. The label shows Little Red Riding Hood and the wolf kissing. Made from 60-120 year-old Albillo Mayor vines planted between 1891 and 1910 at 770-1,000 metres on clay-limestone soils. Fermented with wild yeasts in steel vat with around one week of skin contact, then raised in tank over winter — the cold naturally clarifies the wine. Bottled with nothing added and nothing taken away. Mature apples, orange peel, dried herbs, and a full, textured mouthfeel with gentle tannin. The most famous orange wine of Ribera del Duero.
Amanda
Rosé — Ribera del Duero100% Garnacha Tintorera from 30-90 year-old vines on clay-calcareous and alluvial soils at 700-1,000 metres in the Olmos de Duero valley. Direct-pressed — no skin contact — then fermented with wild yeasts in steel tank and raised over winter, clarified naturally by the cold. Bottled with nothing added, nothing taken away. Pale, fresh, and structured — not a poolside rosé but a serious, gastronomic pink wine with backbone and mineral grip. Proof that Garnacha Tintorera can be elegant rather than merely dark.
El Marciano
High-altitude Garnacha — Sierra de GredosThe Martian. 100% Garnacha from 50-90 year-old vines on decomposed granite soils at 1,000-1,200 metres around Navarredondilla in the Sierra de Gredos — an area famous for UFO sightings. The label depicts two aliens working Alfredo's vineyard at night. Fermented with wild yeasts, including some or all stems depending on vintage, and raised in steel vat. No oak. Ripe, concentrated, lively red fruit with a granite-driven freshness that belies the altitude and sun. The wine that introduced countless drinkers to high-altitude Gredos Garnacha. "Alfredo, you are the martian. That's you arriving on Mars."
El Rey del Glam
Carbonic Garnacha — Gredos & PeñafielThe David Bowie wine. 100% Garnacha, half from old vines on granite in Navarredondilla, Gredos, half from moderately old vines on calcareous clay in Peñafiel. Made by carbonic maceration: grapes are de-stemmed but not crushed, left whole in the vat to ferment inside the berries. The result is fruit-forward, light in tannin, zippy and unexpected — energetic, just like Bowie. Red licorice, cinnamon, anise, black pepper, and a vivid acidity that explodes like a roller coaster cresting the summit. The party wine of the range. The label was drawn after Alfredo sent Michel the song and asked for his reaction.
Castrillo de Duero
Single-vineyard red — Ribera del DueroFrom a single vineyard called La Ladera — 70-year-old Tinto Fino vines on clay-loam soils at 960 metres in the municipality of Burgos, Ribera del Duero. Typically 20% whole cluster, fermented with wild yeasts in steel vat with 12-15 days of maceration, then raised 12 months in neutral French oak. Layered black and red fruit, polished tannins, freshness, and elegance. The most structured and age-worthy of Alfredo's Ribera reds — a wine that shows beautifully at ten years old. A tiny addition of sulfur. Deep, tarry, tobacco-laden with age.
La Olmera
Single-vineyard red — PeñafielOne of two single-vineyard Peñafiel reds (alongside La Guindalera), made with a small addition of sulfur. From old-vine Tinto Fino on the distinctive soils of Peñafiel. Fermented with wild yeasts and raised in used barrels. More concentrated and mineral than Viña Almate, with a savoury, earthy depth that speaks of the clay-limestone hills above the Duero. A step up in seriousness and ageing potential — the wine for those who want to see what Alfredo's old vines can do when given the single-vineyard treatment.
La Guindalera
Single-vineyard red — PeñafielThe companion to La Olmera — another single-vineyard Peñafiel Tinto Fino with a small sulfur addition. Slightly different exposition and soil composition, giving a wine of more red fruit, more floral perfume, and a finer tannic structure than La Olmera. Together, the two wines demonstrate the parcel-specificity that Alfredo is capable of when he focuses on a single site rather than blending across elevations. Both are excellent value for their concentration and authenticity.
Cañonazo
Ancestral sparkling — CastellónFormerly called Perdigón. An ancestral-method sparkling wine from a parcel of young Pinot Noir at 300 metres on limestone in Castellón, near the Mediterranean — 100km north of Valencia — plus a small amount of old bush-vine Garnacha Tintorera. Hand-harvested, direct-pressed into steel vat for primary fermentation, then bottled before fermentation goes completely dry to finish secondary fermentation on fine lees for 9 months. No fining, no filtering, no SO₂. A wild card in the range — Mediterranean sunshine in a bottle, with the same zero-additive discipline as everything else Alfredo makes.
Other Curiosities
Experimental & limited releasesAlfredo's restless curiosity produces a rotating cast of limited cuvées: A dos Tiempos from Navalcarnero; La Asperilla; La Viñuela; Garnacha (a single-varietal Garnacha from Ribera del Duero); and others that appear and disappear according to vintage and vineyard availability. All share the same principles: organic fruit, native yeasts, no additives, used barrels, and labels drawn by Michel. The range is constantly evolving — "in continuous evolution," as Alfredo would say.
Legacy — The Accidental Pioneer
Alfredo Maestro Tejero matters because he is the most accessible gateway to Spanish natural wine — and also one of its most serious practitioners. In a region where nearly 300 bodegas compete to make the darkest, most extracted, most oak-drenched Tempranillo possible, Alfredo makes 13 different wines from 115-year-old vines at 1,200 metres with zero additives and hand-drawn labels featuring Martians and David Bowie. He is simultaneously profound and playful, rigorous and ridiculous — a combination that has made him a cult figure from Tokyo to Brooklyn.
His legacy is methodological. By eliminating every additive — including sulfur for most cuvées — and proving that the wines remain stable, age-worthy, and delicious, Alfredo has demonstrated that natural wine does not have to be a niche curiosity. He makes 115,000 bottles a year. He sells to restaurants and wine bars across the world. His Viña Almate is often the first natural wine a Spanish drinker ever tastes, and it converts them. "These wines are 'more wine'," he says. "They have an 'air' of wine; of grapes. In Spanish, we call it 'vinoso' which means 'of relation' to wine. We shouldn't have to say this, but we do."
His legacy is also botanical and political. By working with Albillo Mayor, Garnacha Tintorera, and Garnacha — varieties that the Ribera del Duero DO suppressed in favour of Tempranillo monoculture — Alfredo has preserved a genetic diversity that would otherwise have been lost. His Lovamor (Albillo) and Amanda (Garnacha Tintorera) are not permitted as DO Ribera del Duero wines, so he bottles them as Vino de la Tierra. The DO's loss is the drinker's gain: two of the most distinctive wines in Spain, made from grapes that the appellation tried to erase.
His legacy is geographic. From Ribera del Duero to Sierra de Gredos to Navalcarnero to Castellón, Alfredo has shown that Castilla y León is not a single terroir but a mosaic — limestone, clay, granite, alluvial sand, each producing a different face of the same grape. His El Marciano introduced the world to high-altitude Gredos Garnacha before Comando G became famous. His Cañonazo proved that ancestral-method sparkling wine could be made from Pinot Noir in Castellón. He is a cartographer of forgotten Spanish vineyards, one retiring farmer at a time.
And his legacy is human. Alfredo is a storyteller — not in the marketing sense, but in the ancient sense. Every label is a myth. Every wine is a character. The Martians, the wolf, Bowie, the doctor who gave him five vineyards — these are not branding exercises. They are the way Alfredo understands his own life: as a series of chance encounters, lucky breaks, and stubborn decisions that led him from economics textbooks to 115-year-old vines. "Wine made with only grapes, well-kept vineyards, and healthy land." It sounds simple. It took him twenty years to learn how simple it is.
