Lupulin

   Also found in: Dictionary/thesaurus 0.01 sec.
Lupulin 

the commercial name for the glandules on the glumes of the fruit system (cones) and perianth of female hop blossoms (Humulus lupulus); also, the secretion from these glandules.

Solidified lupulin is a brownish yellow, sticky, coarse-grained powder containing essential oil, bitters, the alkaloid humulene, humulotannic acid, valerianic acid, gum, resin, wax, and a yellow pigment. Lupulin is used in brewing to give beer a pleasant, slightly bitter flavor, but it can also be toxic. A dose of 1-2 g may be mildly poisonous.

The lupulin that is found in hops is described as both a sedative and hypnotic drug.
By noting the size of the lupulin glands, the microscopic data can also be used to determine the stage of maturity of the strobiles at the time of harvest (Jackson and Snowden, 1968; Neve, 1991; Youngken, 1950).
Lupulin is our way of honoring the hop plant," said brewer Jake O'Mara.
