Amaro Sfumato belongs to the rabarbaro or rhubarb class of Amari. It gets its distinct smokiness from the maceration of Chinese rhubarb. Chinese rhubarb gives this amaro a smoky taste without the accompanying bitterness of wood tannins like smoked whiskey.The result is a unique and complex smoky and earthy flavor. Combined with Creme de Cacao and mole bitters, this Manhattan is reminiscent of s'mores by the bonfire. Make one, strike up a good conversation, and forget that it's below freezing out there.
