Vermouth

The Negroni has a bittersweet taste from the Campari. It can be an acquired taste, but it’s definitely one you should try.

The Hanky Panky Cocktail is a classic that dates back to at least the 1920s, so there have been some variations on it. The overall flavor is bittersweet, like dark chocolate.

The Americano began life as the “Milano-Torino” at Caffe Camparino in the 1860’s, but it was so popular with American ex-pats that it got renamed.

The Algonquin is a very old classic that dates back to at least the 1930s. It features rye bourbon with dry vermouth and pineapple juice, which makes for a sweet, easy-going, slightly tropical cocktail.

If you’ve rejected the Negroni in the past because you don’t like gin, you might want to try The Boulevardier. It uses whiskey instead of gin, and the flavor difference is surprising.
