Zwack Unicum is a Hungarian herbal liqueur from Budapest, bottled at 40% ABV and made from a secret blend of more than forty herbs and spices. Unicum is a Hungarian bitter-style herbal liqueur, drunk as both an aperitif and a digestif; legend has it the drink was created in 1790, and it is produced by the Zwack company according to a secret recipe based on over forty herbs, then matured in oak casks.
The history of the brand is intertwined with that of the Zwack family, which has run the company since the end of the 18th century. The documented history of the liqueur begins in 1883, when József Zwack patented the Unicum name, bottle and label. Production still takes place today at the Budapest distillery on Soroksári út. Most of the herbs and spices used in Unicum come from the Carpathian Basin, but ingredients are also sourced from Morocco, China, India, Sri Lanka, Indonesia, Nigeria, the Americas and Australia.
The process relies on two methods of extracting the aromas. Part of the secret blend is macerated in water for 30 days, while the other part is distilled; then, in a process virtually unchanged for more than 200 years, the two parts are combined and matured in oak casks for six months. Distillation gives Unicum its characteristic aroma and bitter bouquet, while the maturation adds smoothness and body. The dark amber hue is achieved with the addition of caramel.
The profile is dominated by a pronounced bitterness balanced by herbal and spicy notes. The colour is dark, chestnut brown with coppery reflections. The nose reveals fresh, tart herbal notes with menthol mint, a touch of cherry and a certain sweetness; on the palate the liqueur is thick and powerful, dry and distinctly bitter, while in the mid-palate a gentle, slightly berry-like sweetness softens the strong bitterness, and the finish is slightly sharp and heavily bitter. This bitter herbal liqueur is drunk mainly as an aperitif before a meal or a digestif afterwards.
