The Berlin Lawyer & the Frequency of Wine

The story of Horst Hummel is the story of a man who went looking for his past and found his future. Born near Stuttgart to a Schwabian-Hungarian family, he grew up with the knowledge that his great-grandfather had been a winemaker in the Austro-Hungarian empire — one of the Swabian settlers who had populated Villány and its surroundings since the 18th century, bringing with them from the German lands a discipline of agriculture and a reverence for the vine that would outlast empires, wars, and political systems. Horst became a lawyer, established himself in Berlin, and lived what appeared to be a metropolitan life of the mind. But the root, once sensed, demands to be followed. In the autumn of 1997, shortly after the fall of Communism had reopened Hungary to the descendants of its diaspora, Horst travelled to Villány to trace his family's origins. He was, by his own later admission, merely curious — a tourist of genealogy, a lawyer on holiday.

What happened next was neither planned nor calculated, and that uncalculated quality has defined the estate ever since. Horst fell in love with Villány — the southernmost Hungarian wine region, famous for its Bordeaux-style reds, its warm Pannonian climate moderated by the proximity of Croatia, and its limestone loess soils that produce wines of unexpected freshness beneath the ripeness. Being passionate about wine, he casually asked his hosts about the price of vineyards. Within days, he was the owner of a plot. By the spring of 1998, Weingut Hummel was operational — a German lawyer commuting between Berlin and Villány, making wine on weekends and holidays, building a cellar in a region he had known for only weeks but to which he was bound by blood, intuition, and the sudden, absolute conviction that this was where he was meant to be. The original property included Portugieser, Kékfrankos, Cabernet Sauvignon, Cabernet Franc, and Merlot — the classic Villány portfolio — and Horst soon added Furmint, Hárslevelű, and Traminer, as if to prove that his ambition was not merely to replicate Bordeaux but to create something specifically, irreducibly Hungarian.

The early years were a balancing act between two lives — the law office in Berlin and the vineyard in Villány, the briefcase and the pruning shears, the court date and the harvest date. Horst is described by those who know him as quite an intellectual — a man who thinks in systems, questions assumptions, and refuses to accept that wine is merely agriculture or merely commerce. This intellectual restlessness drove him steadily away from convention. The estate was converted to organic viticulture in 2008 and certified in 2009 — a serious commitment in a region where chemical viticulture was still the default. In 2016, he began using biodynamic preparations, making Hummel one of only two biodynamic wineries in Villány (the other being the Demeter-certified Wassmann). And in 2020, he took the further step of developing and implementing Natural Synergistic Winegrowing (NSW) — his own viticultural framework, published as a book, which integrates organic and biodynamic practice with a radical openness to unconventional methods, including the use of specific sound frequencies played to barrels to address microbial faults such as mousiness and volatile acidity. The lawyer had become not merely a vigneron but a theorist, an experimenter, and a provocateur.

In 2023, the estate underwent a restructuring. The domaine now farms 2.5 hectares of estate vineyards planted with Hárslevelű, Furmint, Portugieser, and Merlot, while continuing to produce other wines from carefully sourced grapes outside the estate. This contraction was not a retreat but a refinement — a deliberate focusing of energy on the parcels that best express the Villány terroir, and a willingness to supplement with purchased fruit rather than compromise quality by farming marginal land. Horst still lives in Berlin, still practices law part-time, and still commutes to Villány with the regularity of a man who has two homes and cannot imagine abandoning either. The Swabian return is complete: the great-grandson of an Austro-Hungarian winemaker has become, through accident and then through choice, a winemaker himself — not in the empire that vanished, but in the republic that replaced it, on the same soil, with the same discipline, and with a philosophical rigour that would have astonished his ancestor and would not have displeased him.

The cellar philosophy at Weingut Hummel is governed by a principle of radical non-intervention, tempered by an intellectual openness that distinguishes Horst from the more dogmatic practitioners of natural wine. All wines undergo spontaneous fermentation — no selected yeasts, no enzymatic additions, no chaptalisation, no acidification, no fining, and no filtration. The only additive permitted is a small amount of sulfur dioxide, used with restraint and transparency, generally keeping total SO₂ below 10 mg/L. The goal is not zero-sulfur purity but wine that is alive, stable, and expressive — wine that reflects the variety, the soil, and the unique Villány climate without the overlay of oenological technology. As Horst insists, the quality of the grapes determines the potential of the wine; a wine can only be as good as the grapes allow it to be. The cellar's role is not to improve but to protect.

For the white wines, the approach is deliberately unconventional in a region dominated by red. Depending on the variety, the whites are fermented on the skins for 3 to 20 days — a spectrum that ranges from brief maceration for texture to full orange-wine extraction for the Traminer and Furmint. After pressing, they are matured on the lees in tanks or used barriques, gaining body and savoury complexity without the woody flavour of new oak. The skin contact lends a gentle phenolic grip, a hazy luminosity, and an aromatic depth that conventional white winemaking would strip away. The Traminer, in particular, becomes something exotic and almost archaeological — a wine of rose petal, lychee, and tannic structure that challenges the region's reputation for one-dimensional reds.

For the red wines, the method is equally restrained and equally specific. Fermentation occurs in open vats with gentle extraction — pump-overs and punch-downs calibrated to preserve freshness and suppleness rather than to extract maximum colour and tannin. The wines remain on their lees for 2 to 4 weeks, macerating slowly, absorbing the savoury, yeasty complexity that lees contact provides, and then they are transferred to used oak barrels of different sizes, ages, and origins for ageing of up to two years. The oak is never new; it is always used, always neutral, always respectful of the wine's own voice. The result is a portfolio of reds that are distinctively fresh, high-toned, and supple — wines of obvious concentration but also of lift, clarity, and a mineral tension that belies the warmth of the climate. The Kékfrankos is spicy and stony; the Portugieser is light and peppery; the Cabernets are structured but not ponderous; the Merlot is plummy but not flabby. These are not blockbuster wines; they are wines of thought.

And then there is the frequency — the most controversial and most characteristic aspect of Horst's cellar work. Since developing Natural Synergistic Winegrowing (NSW), he has experimented with playing specific frequencies to barrels to address microbial faults such as mousiness and volatile acidity — conditions that would doom a conventional wine to blending or destruction. The method, derived from his broader research into the energetic and informational dimensions of living systems, is not pseudoscience in Horst's framing but an extension of biodynamic logic: if the moon's gravity can influence sap flow, if planetary rhythms can guide planting dates, then sound waves — which are, after all, physical vibrations — can influence microbial populations and chemical equilibria in a fermenting liquid. Whether one accepts the physics or not, the results are in the bottle: wines that are clean, vibrant, and free of the faults that often plague zero-additive natural wines. The frequency is not a trick; it is a tool — and it is used by a man who has written a book about it, who lectures on it, and who treats his cellar as a laboratory for the reconciliation of ancient intuition and modern inquiry.

To understand Horst Hummel, one must understand the commute — the regular journey between Berlin and Villány, between the law office and the vineyard, between the briefcase and the pruning shears. He is not a full-time vigneron in the romantic sense; he is a part-time lawyer who happens to make some of Hungary's most intellectually serious wine. This bifurcated life is not a compromise but a source of strength. The lawyer's mind brings rigour, documentation, and a resistance to magical thinking; the vigneron's heart brings intuition, patience, and a willingness to listen to the vineyard. The two identities are not in conflict; they are in dialogue. The legal training prevents him from falling into the anti-intellectualism that sometimes characterises natural wine; the viticultural practice prevents him from falling into the technocratic abstraction that sometimes characterises the law. The result is a man who writes books about frequencies in barrels, who names his wines after states of being, and who treats the cellar as both a laboratory and a library.

The conceptual identity is equally central. The Trilogie der Grundbefindlichkeiten — Despair, Serenity, Bliss — is not a marketing gimmick; it is a philosophical statement about the emotional capacity of wine. Horst believes that wine can and should express not merely place and variety but mood, ontology, and the human condition. The Merlot named Despair is not a sad wine; it is a profound one, a wine that requires patience and yields wisdom. The Portugieser named Serenity is not a simple wine; it is a balanced one, a wine that asks nothing and gives everything. The TBA named Bliss is not merely sweet; it is ecstatic, a wine that approaches the edge of the sayable. This conceptual framing places Horst in a lineage of European intellectual vignerons — from the Benedictine monks who named their wines after saints to the modernists who label their cuvées with catalogue numbers — but with a distinctly Germanic, psychological twist. The wines are not named after places or people; they are named after states of soul.

The future of Weingut Hummel is tied to the maturation of the restructured 2.5-hectare estate, the continued refinement of Natural Synergistic Winegrowing, and the gradual acceptance — or rejection — of frequency-based cellar interventions by the broader wine world. The Fercsy Schiller will continue to be the estate's calling card — a light, joyful, immediately accessible wine that proves Villány can do more than heavy reds. The Kékfrankos Spatz will continue to carry the banner of Hungarian Blaufränkisch, challenging Austrian dominance with a limestone-loess freshness that is distinctly Villány. The Dumbledore will continue to demonstrate that Bordeaux blends in Hungary need not imitate Bordeaux. And the Trilogie will continue to sell out — not because it is rare, but because it is true. The Berlin lawyer will continue to commute, the book will continue to be discussed, the frequencies will continue to be played, and the wines will continue to make themselves, as Horst says, with and never against nature.

In an age of increasing homogenisation in wine — of global varieties, engineered yeasts, and technological fixes — Weingut Hummel stands as a compelling alternative, not because it rejects modernity but because it has embraced a deeper modernity: one that values limestone loess over brand recognition, Kékfrankos over Cabernet monoculture, spontaneous fermentation over selected yeast, skin maceration over sterile clarity, used oak over new-barrel prestige, frequency over filtration, the conceptual triptych over the anonymous blend, the part-time lawyer's rigour over the full-time vigneron's dogma, and the specific voice of Villány's Jammerthal, Várerdö, and Verebes-rét over the standardised replication of a global luxury style. Horst Hummel is not merely making wine; he is proving that a Berlin lawyer can become a biodynamic theorist without losing his mind, that a Swabian-Hungarian family can recover its birthright across the distance of generations, that sound waves can stabilise what sulfur cannot, and that the most serious wine is often the most playful. From Stuttgart to Berlin, from Berlin to Villány, from the law office to the open vat, from the frequency generator to the Trilogie der Grundbefindlichkeiten: all united in one bottle, one slope, one unanswerable argument for the possibility of authentic, place-specific, intellectually rigorous, naturally synergistic wine from the limestone loess of Hungary's deep south.
