About a year ago, St. Agrestis, a spirits company based in Brooklyn, introduced a bottled Negroni cocktail. The bitter ruby-colored aperitif spirit in the mix was called Inferno, also made by St. Agrestis, but not sold separately until now. Inferno has all the bitter complexity of Bette Davis in “All About Eve.” Louis Catizone, a founder of St. Agrestis, said the bitter is made without any artificial coloring and relies on botanical ingredients, including gentian root and hibiscus. It works with a splash of orange juice or in any of the spritzes and cocktails that usually demand the Italian version.
