I just saw this and was wondering how it would go in an IPA. Essentially its Lupulin concentrate.
"Lupulin is the glandular powder separated from the strobiles of the Humulus lupulus (hops) plant. It has sedative effects on the body and mind and stimulates sleep. This powder is separated by beating or rubbing the strobiles of hops, and then sifting them. The sifting is necessary to remove the broken bracts and other vegetable parts. About 10 per cent of lupulin is thus obtained from the dried hops.
The powder is bright brownish-yellow and become resinous. Lupulin is chemically related to THC.
Lupulin has the odour and common taste of hop."
