In a nutshell:
A well known, classic, bitter, herbal Italian amaro from Fratelli Branca of Milan.
This very well known brand of amaro, or bitters, is still made to the same secret recipe of over 40 herbs and spices that's been used since 1845. It's aged for a full year in barrel before bottling. With a pale brown colour it's intensely aromatic, almost pungent, with a distinctly medicinal, herb character. But it has a good balance and richness and is excellent served on ice as a digestif, or mixed in cocktails.
