Montenegro Amaro. One of the lightest and gentlest amari, with orange and rosewater notes, Montenegro was named to commemorate the marriage of Princess Helen of Montenegro to Italy's King Victor Emmanuel III in 1896. Amaro Montenegro, "the liqueur of the virtues", was created in 1885 thanks to the lengthy, impassioned experiments of a famous distiller and herbalist, Stanislao Cobianchi. The name "Montenegro" is a dedication to the beautiful princess Elena of Montenegro, who was engaged to Victor Emanuel III. In its over 100 years of history, Amaro Montenegro has seen its success grow continuously up to the present day, now being one of the leading brands on the Italian market.
