Lupulin (hop absolute/CO2) smells intensely of fresh hops — a green, bitter-herbal aroma with resinous, slightly spicy and hay-like facets. Over time it reveals earthy, tobacco-tinged and mildly beer-like undertones with a dry aromatic finish.AI · claude-opus-4-7

The intensely yellow, dustlike, yet sticky substance.
Extracted with volatile solvents to produce an oleoresin, or, in the case of alcohol-extraction, a tincture.
Lupulin can lend a rich, natural body to many fruit flavors, particularly apple, and it blends well with the spicy flavors, e.g. as a modifier in ginger ale flavors, or in the complex flavors where sweet or bitter orange are among the carriers.
Lupulin is very rarely used as such, but it might find application in flavors or perfumes, e.g. in combination with Armoise, Wormwood Absolute, etc.
Various flavoring materials are prepared from lupulin. It can be used in a multitude of flavors other than beer.
When lupulin is extracted with ethyl alcohol, and subsequently washed with weak alcohol and, finally, with water, a cloudy tincture is produced. This tincture can be distilled to produce a 45%, 50% or 60% alcoholic, clear tincture known as Lupulin Aromadistillate.
