The Volcanic Alchemist & the 1666 Seal

The story of Pivnica Čajkov begins not in the modern era but in the 17th century, when the Uhnák family received a seal from the Archbishop of Esztergom in 1666 — a document that authorised them to trade in wine and agricultural products and that remains the symbolic and material proof of the family's ancestral abilities. For generations, the Uhnáks were among the largest growers and makers of wine in Čajkov, a village nestled in the southern foothills of the Štiavnica Mountains. Marek's great-grandfather was the first to send his sons to study viticulture formally, creating a family tradition of education and refinement that Marek himself would continue at the Oenology Secondary School in Modra and later at Mendel University in Brno.

Marek Uhnák grew up among the vineyards and cellars of Čajkov — "my life has been tied with wine ever since I was born," he says. But his path to becoming the estate's modern architect was not immediate. Like many young winemakers of the post-communist generation, he initially pursued modern technology, new production methods, and the latest oenological innovations. He wanted to be better than those before him, to prove that a new generation could take over the world of wine with science and progress. With the benefit of hindsight, he looks back on that period and smiles — not with regret, but with the recognition that those experiments were the irreplaceable experience that taught him how precious and unique Čajkov truly is.

The turning point came with Pesecká Leánka — the old Carpathian variety that had been the most frequent wine in Čajkov cellars but was pushed by the socialist system into the role of a volume generator for wine factories. During his studies in Modra, Marek was shocked to discover that Pesecká had almost disappeared from the surrounding vineyards. He made it his guinea pig, trying every possible combination of production procedures: strictly reductive, oxidative, skin contact, flor ageing, botrytis-affected harvests, cuvées, and blends. The hectic period taught him the lesson that would define his philosophy: we can adjust neither the variety nor the terroir. It is we who must adjust to them, overcome our pride, stop playing omniscient, and start respecting them.

Today, Marek approaches grapes and wine with respect and humility — "the only way how a man may serve as a tool to improve and present wine." He no longer chases success, points, or medals. He does not look for "the best" wine. He knows that the true gold is hidden in the character and individuality of the unique Čajkov region, and that those specific features cannot be forcibly pressed into glasses. The first commercial vintage under his direction was released in 2015, but the philosophy is centuries old: wine of our grandparents, made with the knowledge of the present and the patience of the past.

The winemaking philosophy at Pivnica Čajkov is governed by a principle of radical responsiveness: the wine is not a product of a plan but a response to the variety and the harvest. Marek Uhnák does not set out to "make" a particular wine; he listens to what the vintage offers and shapes his interventions accordingly. The only constants are the organic fruit, the volcanic soils, and the refusal of all industrial shortcuts. Everything else — vessel, maceration length, ageing time, flor contact, blending — is variable, intuitive, and determined by the raw material.

Fermentation is spontaneous, carried out by indigenous yeasts with no selected strains, no enzymes, and no oenological additives. Marek processes grapes without pressing when possible, avoiding mechanical damage to the delicate skins of varieties like Pesecká Leánka, whose flesh is almost liquid and whose skin is thin and fragile. The whites range from light, refreshingly flowery dry wines to rich, full-bodied sweet wines, from pet-nats to skin-contact expressions, from reductive stainless-steel ageing to oxidative flor development. The reds are fermented with gentle extraction and aged in a mix of vessels. This is not chaos; it is disciplined creativity — each wine made in its own way, with its own logic.

The cellar is avant-garde in its eclecticism. Marek uses stainless steel tanks, an assortment of barrels in different sizes, wood types, and ages, and varying degrees of skin contact. Some wines age under flor — a veil of yeast that imparts saline, nutty complexity. Others undergo complicated cultivation of botrytis-affected grapes for sweet cuvées. The minerality imparted by the volcanic soils is prominent in all wines, but it presents differently depending on the variety: Pesecká Leánka brings juicy grapefruit and dried apricot; Devín brings aromatic intensity; Pinot Gris brings textural depth; Frankovka brings spice and structure. The sophisticated cooking that Marek prepares for his family and friends informs the wines he makes — they are designed for pairing, for contemplation, and for joy.

Sulfur is treated with transparency and restraint. The total sulfur content is stated on every label — a practice of radical honesty in a region where industrial wines often hide their chemical load. Filtration is avoided; the wines are bottled with their natural sediment, native yeasts, and living microbial character intact. The result is a portfolio that is vividly individual, faceted, polished, and fascinating — wines that are as inventive as they are classical, as contemplative as they are chuggable, and as deeply Slovak as they are internationally resonant.

To understand Pivnica Čajkov, one must understand the volcanic alchemist — a winemaker who treats the cellar not as a factory but as a laboratory where past and future converge. Marek Uhnák is wildly creative yet deeply classical, contemplative yet unafraid to produce wines that are "chuggable." His avant-garde methods — flor ageing, botrytis cultivation, skin contact, pet-nat, co-fermentation — are not gimmicks; they are tools for exploring the full potential of volcanic terroir. The alchemist does not chase trends; he chases truth in the glass, and he finds it by listening to the variety, the vintage, and the soil rather than imposing a predetermined style.

The restorer of Pesecká identity that Marek embodies is equally central. When he discovered that Pesecká Leánka had nearly disappeared from the region during his studies, he made it his mission to restore the variety to its rightful place as the queen of Čajkov. He identified four distinct clones in his vineyards, each with unique characteristics. He experimented with every possible production method until he understood that the variety's tender character is disturbed by selected yeasts and additives — that the only proper way is to respect the forces of nature. Today, Pesecká Leánka is the estate's signature, produced in more styles than perhaps any other winery in the world: dry, sweet, skin-contact, sparkling, botrytised, and flor-affected. The restorer does not merely make wine from Pesecká; he has resurrected a cultural inheritance.

The future of Pivnica Čajkov is tied to the continued organic and regenerative farming of the ten volcanic parcels, the deepening of neighbourly cooperation toward a chemical-free region, and the expansion of Marek's experimental programme. The Intacto will continue to be the elegant signature white. The Rustical will continue to push the boundaries of skin-contact Pesecká. The Queen Mom will continue to prove that Slovak sweet wine can achieve world-class complexity. The Red Gull will continue to defy categorisation. And the Extracta will continue to demonstrate the volcanic soul of Slovak red wine. The 1666 seal, the UNESCO mountains, the four clones, and the ten parcels will all continue to inform every bottle.

In an age of increasing homogenisation in wine — of global varieties, engineered yeasts, and technological fixes — Pivnica Čajkov stands as a compelling alternative, not because it rejects Slovakia but because it has embraced a different Slovakia, one that values the 1666 seal over the modern trademark, Pesecká Leánka over Chardonnay, volcanic tuff over flatland loess, spontaneous fermentation over selected yeasts, flor ageing over sterile filtration, and the specific voice of the Sitno stratovolcano over the standardised replication of a global luxury style. Marek Uhnák is not merely making wine; he is continuing a lineage — from the Archbishop's authorisation to the Modra school to the Mendel University to the avant-garde cellar, from the confiscated vineyards of communism to the organic slopes of today, from the forgotten grape to the restored queen. The seal, the volcano, the four clones, the ten parcels, the zero additives, the sulfur transparency, and the name that has meant volcanic Slovak wine for four centuries: all united in one bottle, one slope, one unanswerable argument for the possibility of authentic, place-specific, historically rooted, creatively evolving artisan wine from beneath the collapsed caldera.
