Hops have been utilized by brewers for centuries to contribute bitterness,
antimicrobial preservation and desirable aromatic profiles to beer. The hop
cone is a small, lightweight, high moisture content flower which produces
lupulin glands containing resins and essential oils. Due to the high harvest
moisture content (75% wet basis), hops must be rapidly dried to properly
preserve for long term storage and brewing. The objectives of this research
were to investigate the relationship between different airflow conditions
during drying and the effects to the essential oil content. The results of this research will aide hop growers’ decision making related to airflow rates, drying temperature and appropriate equipment selection to produce a higher quality hop.
