The Haystack is a creation of a London bartender from 2017. He states that it's a "yellow version of Sam Ross' Paper Plane". I would say that he has drawn inspiration from the Paper Plane but I wouldn't refer to it as a variation as the flavour profile differs significantly.Woody, herbal, bitter tones from the Suze (Gentian liqueur), sweet stone fruit courtesy of the Apricot Brandy Liqueur and a touch of sour from the fresh lemon juice.
