Made with Zucca and it is a very good drink. The rabarbaro adds a different kind of bitterness that complements the Campari and shows up towards the end of the evolution, along with its signature smoked accents. Still recognizably in the Negroni family (more so than some other riffs out there), but distinct enough to have its own character. Highly recommended.
Didn't have rabarbaro available so used 1/3 oz averna and 1/4 !rhubarb liqueud instead. Was really tasty! Averna brought up some smoky chocolatey notes and the rhubarb provided tartness.
this sounds delicious as a drink, I'm going to try this because I have some homemade rhubarb liqueur, but also rhubarb and averna are nothing like rabarbaro tastes like :P
Just tried this with Amara Sfumato Rabarbaro and enjoyed it greatly. The smoky note on the amaro complements the bitter Campari so well and sweet vermouth mellows everything out a bit. Really complex and enjoyable drink that evokes autumn for me and that I'll be making again throughout the fall and winter season.
