A century and change before Zagreb's craft-beer boom, one name already dominated the city's glasses: Zagrebačka pivovara. Founded in 1892 and still brewing in the Črnomerec district today, the company has outlived a near-bankruptcy, two world wars, a fascist regime, socialism and privatisation — and its story reads like a potted history of Zagreb itself.

The idea came out of the Croatian Discount Bank, whose director Franjo Šverljuga convened the founding assembly in May 1892. With capital of 300,000 forints split into 1,500 shares, the brewery was built in the city's western industrial zone, its main building stretching 100 metres along the street. The contemporary papers were suitably dazzled: Narodne novine described a beer garden for 1,500 guests, expandable to 5,000 for concerts and celebrations, plus a fishpond doubling as an ice source — and, on paper at least, a skating rink that never materialised.

When the brewery opened on 12 July 1893, Zagreb turned up en masse. Trams ran until two in the morning ferrying crowds to the garden, and the opening day drew an estimated 8,000 visitors. The restaurant became a local institution for decades.

Success wasn't automatic. Fierce competition from a dozen-odd Croatian breweries and Austrian imports nearly sank the company by 1910, until a capital merger with breweries in Sisak and Nova Gradiška rescued it. Industrialist Samuel David Alexander then modernised the operation, linking it to the rail network and expanding sales down to Dalmatia once the Split line opened in 1925. The 1940s brought tragedy: the Alexander family, who were Jewish, were stripped of the business under discriminatory regulations, and Samuel died in hiding in 1943 while relatives perished in Ustaša camps. Brewing stopped entirely in 1944 for lack of raw materials, restarting only after Zagreb's liberation in May 1945.

Under socialism the company roared back. Output jumped from 60,000 hectolitres in 1952 to a million by 1969, and until 1970 it brewed more than half of all the beer produced in socialist Croatia. At its peak it ran plants in Zagreb, Karlovac, Daruvar and Otočac with 1,600 employees — meaning today's market rivals once shared a single enterprise. In 1993 it was sold to Belgium's Interbrew, and since 2012 it has belonged to Molson Coors. It now produces about 1.5 million hectolitres a year with roughly 650 staff.

For travellers, this is more than corporate trivia. Zagreb remains one of Europe's great beer cities, and understanding Zagrebačka pivovara explains why its lagers are such a fixture at every market stall and garden café. The old brewery quarter in Črnomerec sits near Ilica, an easy tram ride west of the centre, and pairs naturally with a crawl through the Upper Town, where small breweries were pouring as far back as the 14th century. Raise a glass of Ožujsko — the company's flagship — and you're drinking a piece of the city's survival story.
