Montenegro is a popular Italian liqueur and a type of amaro that has been produced in Bologna since 1885. It is made with 40 botanicals sourced from four continents, and it remains one of the most popular and best-selling amari in Italy.
The production process is complex and includes several techniques, and though the exact botanical blend remains secret, some of the ingredients include oranges, wormwood, cloves, cinnamon, and nutmeg. The liqueur is amber-colored, with a rich, bittersweet flavor.
