The Stone Cellar Poet & the Travertine Slopes
Mäsiar Wines is one of the most exciting new voices in Slovak natural wine — a low-intervention micro-winery founded by Marcel Mäsiar in the historic town of Levice, in the Tekov wine region of southwestern Slovakia. Working from stone cellars carved into the earth beneath the town, Marcel farms approximately 1.5 hectares of young, organically cultivated vineyards on windy south-facing slopes where travertine runs through the subsoil — a porous, mineral-rich limestone formation that imparts a distinctive chalky freshness and saline edge to the wines. The philosophy is disarmingly direct: personal cultivation without synthetic chemicals, hand-harvested fruit, destemmed and macerated with patience, then aged in a combination of glass bottles, stainless steel, and wooden barrels within the cool stone walls of the cellar. The wines are bottled unfiltered, with no sulfur or only the lightest touch, and they carry the playful, experimental energy of a winemaker who is not afraid to challenge convention. From the tropical pet-nat to the macerated whites and the suggestively named young-vine cuvées, Mäsiar Wines represents a new generation of Slovak natural wine — rooted in volcanic Tekov soil, fermented with wild yeast, and bottled with a wink.
Marcel Mäsiar & the Stone Cellars of Levice
The story of Mäsiar Wines begins with Marcel Mäsiar — a winemaker who arrived at natural wine not through inheritance but through conviction, building his cellar and his reputation from the ground up in the historic town of Levice. The Tekov region, where Levice sits, has been a winegrowing area for centuries, but the communist era and the industrialisation of Slovak viticulture left many of its traditional cellars abandoned and its vineyards collectivised. Marcel saw not ruins but possibility: the stone cellars beneath the town — cool, humid, and acoustically alive — were the perfect womb for wines that needed no temperature control, no stainless steel cathedral, and no technological intervention.
The winery's name is simply the winemaker's name — Mäsiar, the Slovak word for butcher, transformed into a brand with a sense of humour and a taste for the unexpected. The tagline says it all: "I don't know the question, but the answer is wine." This is not a marketing slogan invented by an agency; it is the manifesto of a man who believes that wine is the solution to most problems, and that the best wines are made by those who do not overthink the process. Marcel founded the winery around 2015, planting new vineyards on the slopes around Levice and gradually converting them to organic cultivation — not through certification bureaucracy, but through the empirical elimination of synthetic herbicides, pesticides, and chemical fertilisers.
The turning point in the estate's visibility came with the ERUPTED wine salon — an event organised in an old synagogue in Levice in collaboration with Marvla TINDO and the local tourism board. ERUPTED put Levice on the map of the international natural wine community, drawing visitors from across Central Europe to taste the volcanic, low-intervention wines of the Tekov region. Marcel's macerated whites and pet-nats became talking points — wines that were unapologetically cloudy, aromatically bold, and structurally unconventional. The suggestion that his range would benefit from the complete elimination of sulfites only spurred him further down the path of zero-addition experimentation.
Today, Mäsiar Wines operates from two connected spaces: the production and tasting facility at Pod Kalváriou 6271/20, and the historic stone cellars at Kamenné pivnice č. 4147 — a network of underground chambers that maintain natural temperature and humidity throughout the year. Marcel works alone but is deeply embedded in the Levice wine community, collaborating with neighbouring producers, hosting tastings for visitors who bring their own food, and constantly experimenting with new varieties, new vessels, and new levels of sulfur-free winemaking. The estate is young, but its voice is already unmistakable.

Levice & the Travertine of Tekov
Levice sits in the Tekov wine region of southwestern Slovakia, in the Nitra district, near the confluence of the Hron and Ipeľ rivers. It is a town of thermal springs, historic fortresses, and a viticultural tradition that predates the modern Slovak state. The Tekov region is part of the larger Nitrianska wine region, but it possesses a distinct geological and climatic identity: warmer and drier than the northern Carpathian slopes, with a subsoil rich in travertine — a porous, calcareous limestone formed by mineral springs that provides both drainage and a distinctive mineral signature. The town's famous thermal baths are fed by the same geological system that nourishes the vines.
Marcel Mäsiar farms approximately 1.5 hectares of young vineyards on windy, south-facing slopes around Levice. The exposure is critical: the south face captures the maximum sunlight during the growing season, while the persistent wind — which can be fierce on the open Tekov plain — reduces humidity, limits fungal pressure, and thickens the grape skins. The soils are a mixture of clay-loam topsoil and travertine subsoil. The travertine is not merely decorative; it is a living geological formation that continues to precipitate calcium carbonate, maintaining an active lime content in the root zone that contributes to the wines' high-toned acidity, chalky texture, and subtle saline finish.
The vineyards are cultivated organically, though not certified — Marcel prefers to invest in the health of the soil rather than in paperwork. No synthetic herbicides, no pesticides, no chemical fertilisers. Weed control is mechanical or manual; canopy management is done by hand; and the vines are respected according to their natural cycles. The young age of the plantings — many established in the mid-2010s — means that the vines are still developing their root systems, but the travertine subsoil encourages deep penetration, and the windy conditions produce small, thick-skinned berries of surprising concentration. The result is fruit that enters the cellar with robust natural defences and a vital microflora of indigenous yeasts.
The climate is warm continental, with hot, dry summers and cold winters. The south-facing slopes accumulate heat during the day, while the wind and altitude provide enough cooling to preserve acidity. Rainfall is moderate, and the travertine's porosity prevents waterlogging even in wet years. The combination of warmth, wind, and calcareous soil creates conditions that favour aromatic white varieties — Sauvignon Blanc, Chardonnay, Tramín — while also allowing early-ripening reds like Pinot Noir to achieve full phenolic maturity. It is not the dramatic volcanic landscape of the Sitno volcano twenty kilometres to the north, but it is a terroir of quiet mineral intensity — of warm stones, thermal waters, and ancient Carpathian limestone.
Mäsiar Wines is located in Levice, in the Tekov wine region of southwestern Slovakia. Founded around 2015 by Marcel Mäsiar. Approximately 1.5 hectares of young, organically cultivated vineyards on windy south-facing slopes. The winery operates from a production facility at Pod Kalváriou and historic stone cellars at Kamenné pivnice. The estate is a rising star in Slovak natural wine and a key participant in the ERUPTED wine salon that put Levice on the international natural wine map.
The soils are clay-loam over travertine — a porous, calcareous limestone formed by mineral springs that provides both drainage and active lime content. The travertine contributes a chalky texture, high-toned acidity, and subtle saline note to the wines. The windy, south-facing slopes reduce humidity and thicken grape skins, producing concentrated fruit with natural defences. A terroir of thermal springs, warm stones, and quiet mineral intensity that favours aromatic whites and early-ripening reds.
The vineyards are cultivated organically without certification — no synthetic herbicides, pesticides, or chemical fertilisers. Mechanical weed control, hand canopy management, and respect for natural cycles replace chemical intervention. The young vines, planted in the mid-2010s, are developing deep root systems in the travertine subsoil and producing small, thick-skinned berries of surprising concentration. A farm of empirical patience, where the health of the soil is built through labour rather than purchased through chemistry.
The winery's historic stone cellars at Kamenné pivnice provide naturally cool, humid conditions for fermentation and ageing without temperature control. These underground chambers, carved into the earth beneath Levice, are the traditional heart of Tekov winemaking. The ERUPTED wine salon — held in an old synagogue in collaboration with Marvla TINDO — demonstrated the cultural vitality of this historic space. A winery of stone, shadow, and community.
Maceration & the Pet-Nat Playground
The winemaking philosophy at Mäsiar Wines is governed by a principle of playful minimalism: intervene as little as possible, but never be afraid to experiment. Marcel Mäsiar does not follow a rigid natural wine dogma; he follows his palate, his curiosity, and the specific character of each vintage. The core practices are consistent — hand harvest, destemming, spontaneous fermentation with indigenous yeasts, maceration for whites and reds alike, ageing in a mix of vessels, and bottling unfiltered with minimal or no sulfur — but the details change from year to year, variety to variety, and cuvée to cuvée. This is not inconsistency; it is creative responsiveness.
Maceration is a central technique for both whites and reds. The white grapes — Sauvignon Blanc, Chardonnay, Tramín, Welschriesling — are given skin contact ranging from a few hours to several days, extracting colour, texture, phenolic complexity, and natural preservatives from the thick skins of the wind-stressed berries. The reds are fermented as whole berries or with partial whole clusters, with gentle extractions that prioritise freshness and drinkability over power and tannin. Fermentation is spontaneous, carried out by the indigenous yeasts that colonise the organically farmed fruit. There is no temperature control, no selected yeast inoculation, no enzymatic correction, and no chaptalisation.
The ageing vessels are deliberately eclectic: glass bottles for some cuvées, stainless steel tanks for others, and wooden barrels for those that benefit from gentle micro-oxygenation. There is no fixation on new oak or barrel toast; the wood is used as a neutral, breathable container rather than a flavouring agent. The stone cellars provide all the thermal stability required, and the wines rest undisturbed for months, developing texture, savoury complexity, and natural stability through time and lees contact rather than through chemical additions.
Sulfur is treated with the same experimental pragmatism that governs every other decision. Most cuvées receive no added sulfur at all — not on the grapes, not during fermentation, not at bottling. For a small number of wines, a minimal addition of 10 to 20 milligrams per litre may be made when Marcel judges it necessary for stability, but the trajectory is unmistakably toward zero. The wines are bottled unfiltered and unfined, carrying their natural sediment, native yeasts, and living microbial populations. The result is a portfolio that is vivid, sometimes hazy, always aromatically bold, and structurally honest — wines that taste of the travertine slopes, the Tekov wind, and the stone cellars of Levice.
The Pet-Nat Playground & the Tropical Spirit
Among Mäsiar Wines' most celebrated creations is the Tropical pét-nat — a naturally sparkling wine that captures the exuberant, experimental spirit of the estate. Made from Sauvignon Blanc and bottled during fermentation to capture natural CO₂, the Tropical is unfiltered, undisgorged, and bottled with zero additions. It is a wine of hazy golden colour, persistent mousse, and aromatic intensity — tropical fruit, citrus blossom, and a subtle chalky minerality from the travertine. The pet-nat format is not merely a trend for Marcel; it is a logical extension of his low-intervention philosophy. By bottling during fermentation, he avoids the need for disgorgement, dosage, or sulfur, and he produces a wine that is alive, evolving, and joyfully imperfect. In a region where sparkling wine has historically meant industrial prosecco-style production, the Tropical pét-nat is a declaration of independence — a wine that proves Slovak bubbles can be natural, characterful, and unmistakably place-specific.
The Portfolio & the Cuvées
Mäsiar Wines produces a small, experimental range of natural wines from approximately 1.5 hectares of organically cultivated vineyards on travertine slopes around Levice. All grapes are hand-harvested, destemmed, and fermented spontaneously with indigenous yeasts. Maceration is employed for whites and reds alike. The wines are aged in a combination of glass bottles, stainless steel tanks, and wooden barrels within the historic stone cellars of Kamenné pivnice. Bottling is done without filtration and with minimal or no sulfur. The following represents the core cuvées as they have emerged from Marcel Mäsiar's first decade of low-intervention winemaking in Tekov.

The Stone Cellar Poet & the Travertine Experimentalist
To understand Mäsiar Wines, one must understand the stone cellar poet — a winemaker who works not in a technological cathedral but in a network of underground chambers carved into the earth beneath a historic Slovak town. Marcel Mäsiar's cellar is not climate-controlled; it is climate-given. The stone walls provide all the humidity and thermal stability his wines need, and the darkness allows them to evolve without the stress of light or vibration. The stone cellar poet does not fight nature; he collaborates with it, using the cellar's natural conditions as a partner in the winemaking process rather than as a problem to be solved with machinery.
The travertine experimentalist identity that Marcel embodies is equally central. He is not bound by appellation rules, family tradition, or commercial expectations. His vineyards are young, his methods are evolving, and his cuvées change from year to year as he tests new varieties, new maceration lengths, new vessels, and new levels of sulfur-free winemaking. The travertine experimentalist is not inconsistent; he is curious. He believes that the best way to honour the travertine slopes of Levice is to listen to what they produce, rather than to force them into a predetermined style. This experimentalism is visible in every bottle: the hazy pet-nat, the skin-macerated Sauvignon, the aromatic Tramín, and the suggestively named young-vine cuvées that carry a sense of humour as well as a sense of place.
The future of Mäsiar Wines is tied to the continued maturation of the young vineyards, the deepening of organic practices, and the gradual elimination of sulfur across the entire portfolio. Marcel will continue to host tastings in the stone cellars, to collaborate with the Levice natural wine community, and to push the boundaries of what Slovak wine can be. The Tropical pet-nat will continue to fizz. The macerated whites will continue to challenge preconceptions about clarity and filtration. And the travertine slopes will continue to produce fruit of increasing concentration and complexity as the vines age.
In an age of increasing homogenisation in wine — of global varieties, engineered yeasts, and technological fixes — Mäsiar Wines stands as a compelling alternative, not because it rejects Slovakia but because it has embraced a different Slovakia, one that values the stone cellars of Levice over the industrial cooperatives, organic cultivation over chemical convenience, indigenous yeast over selected strains, pet-nat energy over standardised bubbles, and the specific voice of travertine and wind over the anonymous replication of a global luxury style. Marcel Mäsiar is not merely making wine; he is building a culture — from the young vines of 2015 to the ERUPTED salon of today, from the stone cellars of Kamenné pivnice to the international natural wine community, from the thermal springs of Tekov to the unfiltered bottle. The stone, the wind, the travertine, the zero sulfur, the pet-nat, the humour, and the name that has meant joyful Slovak natural wine for a decade: all united in one bottle, one slope, one unanswerable argument for the possibility of authentic, place-specific, curiosity-driven, stone-cellar-born artisan wine in the heart of Tekov.
Marcel Mäsiar works in a network of historic stone cellars beneath Levice — cool, humid, acoustically alive spaces that provide natural thermal stability without technology. The stone cellar poet does not fight nature; he collaborates with it, allowing the underground conditions to shape the wines' evolution. This is not rustic nostalgia; it is functional poetry — the recognition that the best cellar is one that has existed for centuries and needs no improvement. The stone cellar is the physical manifestation of Marcel's philosophy: patience over speed, earth over machine, and time over intervention.
Marcel Mäsiar is an empiricist who tests, tastes, and evolves. His young vineyards on travertine slopes are a laboratory where new varieties, new maceration lengths, new vessels, and new sulfur-free techniques are explored vintage by vintage. The experimentalist is not inconsistent; he is responsive — listening to what the travertine produces rather than forcing it into a fixed formula. This curiosity is visible in every bottle: the hazy pet-nat, the skin-macerated whites, the aromatic blends, and the playful names. The travertine experimentalist proves that Slovak natural wine can be both deeply serious and genuinely joyful.
