When it comes to fun, Hungarians know the drill. Budapest offers countless alternatives whether you’re planning to stay sober and visit one of the many escape rooms or spice up the night with a ruin pub crawl. If you’d rather stay on the tipsy side, you can visit a rooftop bar, go wine tasting, or get a taste of Hungary’s (in)famous spirit, pálinka. However, not many know that Hungarians have another magnificent national drink that started its career as a medicine back in 1790. Read on if you’d like to know Unicum a little bit “bitter”!

The film-like history of Zwack Unicum
According to legend it all started with an indigestion problem Habsburg ruler Joseph II experienced in 1790. Luckily, Dr. Zwack, royal physician to the Imperial Court came to the rescue and created an herbal remedy to help the Holy Roman Emperor ingest. In the following decades, the unique elixir spread in popularity until József Zwack, a venturesome descendant of the doctor founded the famous Unicum Company named “Zwack” in 1840. The next milestone for the product was in 1883 when the drink was registered as a “liqueur to protect the strength of the stomach, marketed under the name Unicum”, made according to a recipe from 1790, and poured in the original round bottle with an iconic red cross on its label. By 1895, Zwack was producing more than 200 liqueurs and spirits and was proudly exporting them from the distillery that is still in use today. To this day, the company receives the title of High Representative Imperial and Royal Court Supplier. In 1909, one of the best-known icons of the company, the “wet man”, was created by Viktor Pachl for a poster.

The global crisis of 1920s and ‘30s didn’t spare the Zwack company either. Not only did the domestic market shrink, but exports started to decline as well due to the alcohol ban in the US. To balance this out and take advantage of production capacities, they started manufacturing incandescent and fluorescent lamps. During World War II, Budapest was one of the most heavily bombed cities in Europe, and among the huge losses the city suffered was the Zwack factory getting destroyed to the ground. By the time it was fully restored to its pre-war condition, the factory was nationalized by the communists in 1948 without any compensation. János Zwack, who fled to the United States, later learnt that his family name was still in use: the nationalized company continued to export Unicum from Budapest under the name Zwack. After filing a lawsuit against the Hungarian state, he won an unprecedented victory: the socialist, state-owned company was not allowed to use the name Zwack or Unicum anymore.
The other Zwack, Péter, didn’t stop there, he went straight to Jim Beam to sign a deal for selling vodka, gin, and slivovitz to keep the brand alive. But they didn’t give up on Hungary either! Péter returned to his homeland and partnered up with German liqueur manufacturer Emil Underberg to establish Peter Zwack & Consorten AG and create a joint venture with the still state-owned Budapest Liqueur Company. After the end of the socialist regime, at the fall of communism, in 1992, they repurchased the company from the state as part of a privatization program and established Zwack Unicum, the company we know today.
The tasty products of the Hungarian Unicum
Beside the flagship product made according to the secret formula of more than forty herbs, they offer Unicum Szilva (Unicum Plum), Unicum Riserva and Unicum Barista. Szilva translates to plum, so, as you would expect, it’s rested on prunes and then matured in oak barrels to achieve a light, harmonious, and fruity flavor. Unicum Riserva, dubbed the company’s super premium herbal liqueur, is produced using a unique double-barrel aging process. The liqueur is first matured in 80-year-old barrels, then transferred to barrels from Tokaji cellars, which gives the drink some roundness, softness, and the unmatched character of Tokaj. And finally, Unicum Barista is made using Arabica coffee, combining the tradition of bitter liqueur and coffee consumption.
