Unicum (keserűlikőr) is a bitter herbal liqueur (keserűlikőr, ; in translation: "bitter liqueur") made by Zwack Unicum in Budapest, Hungary. It was registered as a Hungarikum (one of Hungary's national values) in 2015. It is widely known with an origin story in which a court physician serving the emperor presented a special drink, but the registration site itself presents this as "according to the story". No check back to primary sources has been confirmed (see leads for treatment of the origin story).

Scope and provenance of the photo
Identification: Identified as labelled in the source. Unicum is a proper product name, and the entity itself refers to a specific brand (Zwack Unicum), so the appearance of the trademark label is adopted as the subject itself.

Reading the bitterness
Unicum (keserűlikőr) is a bitter herbal liqueur made by Zwack Unicum in Budapest, Hungary. In 2015, it was registered in both the Hungarikumok Gyűjteménye (Hungarikum Collection) and the Magyar Értéktár (Hungarian Value Repository) under the specialist category 『Agrár- és élelmiszergazdaság』 (in translation: "Agriculture and Food Economy"). The registration site says it was registered through the application and review procedure of the Hungarikum Bizottság, under Annex III of the 114/2013. (IV. 16.) Kormányrendelet (the government decree on the protection of Hungarian national values and Hungarikums). This registration is a national appraisal of the Unicum brand itself, not a statutory standard for the entire generic category keserűlikőr.
According to the company's official history, József Zwack began his first brewing and distilling operations in 1840 and registered Unicum as trademark number 805-071 in 1883 (dated May 22 in the source). The founding-year statement appears only in the Hungarian original; the corresponding passage remains untranslated even on the English page, although the English section also gives the trademark-registration details. This is the company's own account, and no corroboration from independent historical sources has been confirmed.
In its section introducing the derivative Unicum Riserva, the company describes the base brand's taste as its 『よく知られたビタースイート(bittersweet)な味』 (in translation: "well-known bittersweet taste"). It contrasts another derivative, Unicum Next (developed in 2004), by saying it reduced the proportion of bitter herbs and brought citrus flavors forward. The company page does not disclose formulation details (specific plant species, proportions, production method, or aging period), and there is no corroboration from independent component analysis.

Note: The registry site displays "Hungarikum - 2015" (registered in 2015). The registration is a national recognition of the specific brand name (Unicum) itself, not a statutory standard for the general category name "keserűlikőr" (bitter liqueur). A record of institutional recognition of the same type as Italy's PAT and GI registration records.

The wording "more than 40 herbs" and "aged in oak casks" appears on the company's history page only in the description of the derivative product Unicum Barista, so it is not recorded here as the composition of the flagship product.
