Not a big fan of Campari but I have to say : " God this drink is good ! " I really like the combinaison of red bitter and pink grapefruit, I think you should give it a try if you aren't a big fan of Campari like me !
I thought I'd love this being a big fan of both Campari/Italian bitter red and grapefruit juice, but the two of them very effectively neutralize each other, creating something far more mild combined than either are on their own. A waste of Campari.
