The founding of the Zwack factory is attributed to József Zwack, who opened his liqueur factory in Pest in 1840 (according to other sources in 1847) in Marokó-udvar (today's Erzsébet tér) to exploit the economic opportunities due to the change in the rules for distilling spirits. Production quickly picked up and in the catalog of the Budapest National Exhibition of 1855 they already reported a decent industry, the employment of 22 workers and exports of HUF 20,000-30,000. A little later, consumers could also receive feedback on the good quality of the products: Zwack products won two gold medals and several awards at the world exhibitions held between 1880-85. In 1881, they registered their first trademarked liqueur, Kincsem liqueur, named after the wonder horse of the time with no small marketing sense. Two years later, their new Unicum bitter liqueur also came under patent protection.
