During the last several years I have gotten into amari or what Italians also call aperitifs and digestifs, both to drink by themselves and to mix into cocktails. I have assembled bottles of Aperol, Averna, Campari, Cynar, Fernet Branca, Meletti and Montenegro. Some of these are more accessible to newbies than others. If you're just starting, I would recommend buying bottles of Aperol, Averna, Meletti and Montenegro. Campari, Cynar and Fernet Branca can be a bit much for some people, but they tend to grow on you. I mainly use these amri for variants on Manhattans, swapping out an amaro for red vermouth. Saluti!
