The Dreher Dynasty and Beer in Trieste: From Habsburg Empire to Lost Memory

The story of the Dreher family and their beer is inseparable from the history of Trieste itself — a tale woven through the rise of Austro-Hungarian industry, the glamour of the Belle Époque, and the bitter aftertaste of twentieth-century decline. To trace the origins of Birra Dreher in Trieste is to discover how a Swabian family of brewers transformed a struggling port-city venture into one of the most storied brewing empires in Europe.

The origins of the Dreher dynasty in Vienna

From Pfullendorf to the imperial capital

The saga begins in 1760, when a young man named Franz Anton Dreher left his native Pfullendorf, in Swabia, and headed for Vienna. After years spent working as a baker's apprentice and then as a Bierkellner — a beer waiter — he managed to lease a small brewery in Oberlanzendorf in 1773. The venture, modest at first, grew steadily. In 1796, Dreher purchased the historic brewery of Klein Schwechat, on the outskirts of Vienna, for 19,000 thalers — a move that would lay the foundation for a dynasty. By 1806, he had earned the title of dean of the Viennese master brewers, a recognition of both skill and tenacity.

The invention of lager and the rise of the Beer King

It was his son, Anton Eugen Dreher (1810–1863), who would revolutionize the brewing world. Trained in Munich at the legendary Sedlmayr brewery (Spaten) and in London at Barclay and Perkins, Anton Eugen combined the best of Bavarian bottom-fermentation techniques with Austrian ambition. Between 1840 and 1841, he developed the Schwechater Lagerbier — a copper-toned, bottom-fermented beer that required cool temperatures for maturation and storage. This Vienna lager conquered Europe's palates and earned him the nickname the Beer King. At the time of his sudden death on 26 December 1863, his fortune was estimated at eight to ten million Gulden.

The founding of the Trieste factory (1865)

An uncertain start and Trieste's great investors

The idea of building Trieste's first beer factory came from Carl Voelkner, a resourceful young entrepreneur from Prague. His enthusiasm attracted some of the city's most powerful figures: Baron Pasquale Revoltella, Elio de Morpurgo (director of Austrian Lloyd), Michele Sartorio (co-founder of Assicurazioni Generali), and the Viennese Rothschild bank. In 1865, they founded the "Prima Società per la Fabbrica di Birra".

Construction, supervised by architect Giovanni Berlam, proceeded at remarkable speed: the factory rose in just 230 days, between 29 May 1865 and 15 January 1866, on a water-rich site previously occupied by a tannery — in the area between Rotonda del Boschetto, via Pindemonte, via dei Bonomo, and via Giulia. Yet the early results were disastrous: quality fell short of expectations, losses mounted, and the venture was put up for sale.

The Dreher takeover

The struggling factory was acquired by Anton Dreher, who saw in Trieste — the Habsburg Empire's great southern port — the perfect gateway for his beers into the Adriatic market. He halted production, modernized the entire plant, and relaunched it. Within a few years, Birra Dreher had conquered the region, its golden foam becoming synonymous with Trieste's booming economy.

Technological innovations under Anton Dreher Jr.

Under Carl Anton Dreher (1849–1921), known as Anton Dreher Jr., the Trieste factory became a laboratory of industrial progress. The plant was the first in the entire Austro-Hungarian Empire to adopt steam as an automatic driving force in the brewing process — a bold leap forward.

Even more revolutionary was the introduction of artificial refrigeration. Between 1868 and 1877, the Trieste factory installed a cutting-edge compressor system designed by the German engineer Carl von Linde, freeing beer production from the constraints of winter ice. That original compressor is now preserved at the Technisches Museum in Vienna.

In 1897, Emperor Franz Joseph honored Anton Dreher Jr. by naming him Knight Commander of the Imperial Austrian Order — a recognition of how deeply the Dreher name had become embedded in the industrial fabric of the empire.

Palazzo Dreher and the social life of the Belle Époque

An architectural extravagance in the city center

The Dreher ambitions were not confined to the factory floor. Between January and February 1907, the company acquired buildings on via San Nicolò and via Cassa di Risparmio, near Piazza della Borsa, with the goal of erecting a palatial structure that would serve as headquarters, residence, and grand restaurant. Construction ran from 1908 to 1910, designed by Viennese architects Emil Bressler (1847–1921) and Gustav Wittrisch in an exuberant eclectic style blending Baroque and Mannerist elements. The foundations used Portland cement mixed with Santorini sand — the same formula used for the warehouses of the Porto Vecchio.

The Restaurant Borsa Vecchia

On 1 April 1910, the Restaurant Borsa Vecchia opened its doors. Advertised in Il Piccolo as "the largest and finest venue in Trieste", it could host 2,000 guests across 19 dining and ballroom halls, crowned by an American rooftop garden overlooking the Adriatic. The tower at the corner of Piazza della Borsa, with its three circular terraces, became the most recognizable feature of the building. Two elevators served the guests, alongside a 200 kg beer hoist and two 100 kg dumbwaiters — beer, it seems, was taken very seriously.

The palazzo quickly became the social hub of Trieste's bourgeoisie, especially among patrons of the nearby Teatro Verdi. Legend has it that the restaurant's musicians would play a signal to announce the end of the theater intermission to guests still savoring their Dreher on the terraces.

The Dreher Tavern at the factory

Another beloved institution emerged in the 1920s and 1930s: the Birreria Dreher, a vaulted beer hall built in the factory's basement on via Pindemonte. In a thoroughly Mitteleuropean atmosphere, patrons lined up for a one-liter stiefel — the traditional boot-shaped mug — and the house specialty, the Piatto Dreher: cold cuts, sausages, and sauerkraut, all for five lire.

Decline and closure

Changes of ownership and the world wars

The First World War paralyzed production and extinguished the Belle Époque optimism that had inspired Palazzo Dreher. The end of Habsburg rule and the shift to Italian sovereignty brought new economic realities. In 1929, the factory was sold to the Luciani family, owners of Birra Pedavena, making Dreher the most widely exported Italian lager. Palazzo Dreher was acquired in 1926 by the provincial economic council and redesigned by architect Gustavo Pulitzer-Finaly (1928–1929) to house the new Borsa Valori e Merci, erasing the original Baroque interiors in favor of a sober Roman-inspired style.

In 1945, the main factory building suffered heavy war damage. Despite this, production recovered and peaked in the postwar decades — by 1974, the plant was bottling an astonishing 500,000 bottles per day.

Crisis, Heineken takeover, and demolition

That same year, the Dutch giant Heineken acquired the company. Just two years later, in 1976, the factory closed permanently. What followed was a painful sequence of broken promises: plans for potato dehydration, ham curing, furniture manufacturing for Snaidero — none materialized. In 1986, nearly the entire industrial complex was demolished to make way for apartment blocks and the Centro Commerciale Il Giulia, which opened in 1991.

Cultural and industrial legacy

Of the vast Dreher settlement, only one monumental building survives: the original factory structure at via Giulia 75, designed by Giovanni Berlam and protected by Italy's Belle Arti heritage authority. Since 2011, it has housed the offices of the Agenzia delle Entrate — the Italian tax authority — its castle-like orange façade standing as a stark reminder of industrial grandeur amid modern anonymity.

Palazzo Dreher endures as well, now home to the Camera di Commercio Venezia Giulia. Inside, a small Museo Commerciale traces the economic history of Trieste — though, regrettably, it has remained closed for years.

The story of the Dreher dynasty in Trieste mirrors the trajectory of the city itself: from the cosmopolitan confidence of the Austro-Hungarian era, through the upheavals of wars and sovereignty changes, to the speculative logic of late-twentieth-century deindustrialization. Where once the aroma of hops filled an entire neighborhood, today there remain only an orange palace, a few old photographs, and the enduring ghost of a stiefel raised in a vaulted cellar.
