One cocktail
I used Campari, Punt e Mes (sweet vermouth) and Citadel gin for the batch I aged. But when I was at a local liquor store, the woman showed me some variations on these, such as a bitters made by Dolin that is a bit more subtle than Campari. So feel free to use brands that you like. Negronis don’t need aging – if you wish, just mix one up in a glass, and enjoy.
1 ounce Campari
1 ounce gin
1 ounce sweet vermouth
optional: a dash of bitters such as orange or creole
orange peel
1. Mix Campari, gin, and vermouth in a tumbler. Add ice and a dash of bitters, if you wish. Garnish with a strip of orange peel

To barrel-age Negronis: Pour 1 part gin, 1 part sweet vermouth and 1 part Campari in a cedar barrel and shake gently to combine. Let age for a couple of months.
