Solid-hop extraction is not bottle marrying. Do not infer a bourbon resting time or compare time alone while ignoring temperature and agitation.
Cascade hops from four processors; model medium 6% ethanol, pH4.2. Week-long cold unagitated and short room-temperature agitated experiments differ in conditions. Figures PDF198–202.
Pellet physical differences generally did not explain week-long aroma extraction. In the shorter experiment, terpene hydrocarbons reached maxima and then declined while terpene alcohols behaved differently. Longer contact therefore did not uniformly increase all extracted aroma compounds.
