Enjoyable Negroni riff. The herbal notes of the Jager pair well with the Plymouth gin. I was out of Cocchi Vermouth di Torino and used Grassotti Vermouth di Torino Rosso which is more fruity and not nearly as rich as the Cocchi. Finding this vermouth to be a bit flat for this cocktail I added a dash of Aztec Chocolate bitters which rounded out the flavors very well. Will definitely try this again once I have a new bottle of the Cocchi.
