Very enjoyable negroni riff. The split vermouth makes it a bit more herbal-forward, and while the Campari is still present, it does not overpower the other ingredients. I agree with previous reviewers on the bitters - I had mine with Dashfire Orange bitters and it was a subtle but welcome enhancement.
Being a lover of a negroni, this looked really interesting to to try, and jeez was it drinkable, I had 2 within the space of 30 mins.
I'm thinking it would be interesting to try grapefruit bitters, but as the other comments say, orange would be great too
Delightful! I have the 1978 Mr. Boston Guide and sure enough, there it is -- albeit with less tequila (1oz) and more Campari (1oz). We'll stick with the modern proportions - it's a new favorite!
