Cover Story: Hops (Humulus lupulus L.) are essential in brewing, providing bitterness, aroma, and flavor. The rising demand for craft beer has expanded hop production into non-traditional regions where climate constraints limit yield and quality. To address these challenges, plant growth regulators (PGRs) have emerged as potential tools to increase productivity and improve hop cone chemistry. This study evaluates PGR applications in field-grown hops, focusing on cone yield, alpha acids, and volatile compounds. The findings provide insights into how targeted applications can enhance yield and chemical composition, supporting hop production in non-traditional regions while improving traits critical to beer quality. View this paper
