Bitter is beautiful, the Italians know this far better than we sugar-addled Americans, and hence Campari - the deeply bitter/citrusy booze with a long secret history (it's said only one person knows the entire recipe).
Campari's most famous drink is the Negroni - deceptively simple and bitter as hell - it rewards only those that earn it. Like a big hoppy IPA you'll likely hate it at first, but then slowly find yourself craving that sharp citrus bite. I dare say it might be my favorite cocktail (at least this week) but something about it being served 'up' didn't do it for me texturally. Bitter sour drinks really click for me when there's some CO2 involved...so out comes the carbonator...
