I noticed one user found the Cornwall Negroni to be "quite bitter," so I decided to minimize the bitterness as best I could. To do this, I used Beefeater 24 for the gin, and Dolin Rouge for the 2nd vermouth. I also used one dash of Regans' Orange Bitters and one dash of Angostura Orange Bitters. The resultant cocktail was only mildly bitter, but pleasantly so. I rated this revised Cornwall Negroni at 4.0. For those who enjoy Negroni-style drink, I think they will find this one to be a delightful cocktail, and one they will come back to often.
