12.10 Hop cones, fresh or dried, whether or not ground, powdered or in the form of pellets; lupulin.
Hop cones are the scaly cone like catkins or flowers of the hop plant (Humulus lupulus). They are used mainly in the brewing industry to give flavour to the beer, but they are also used for medicinal purposes. The cones fall in this heading whether fresh or dried and whether or not ground or powdered or in the form of pellets (i.e., agglomerated either directly by compression or by the addition of a binder in a proportion not exceeding 3 % by weight). Lupulin is a yellow resinous powder which covers the hop cones and contains the bitter, aromatic principle which gives hops their characteristic properties. It is used in brewing as a partial substitute for hops and in medicine. It may be separated from the hops mechanically after drying. The heading excludes :(a) Extract of hops (heading 13.02). (b) Spent hops (heading 23.03). (c) The essential oil of hops (heading 33.01).
