Hop Flavor and Aroma presents new hop-related research. It covers all aspects of hop flavor and aroma, which makes it perfect for brewers, brewing chemists, quality assurance professionals, R&D personnel, flavor chemists, and hop growers and dealers. The 14 chapters in this book are based on research presented at the First International Brewers Symposium held on the Oregon State University campus in Corvallis, Oregon. This monograph brings together world experts from the academic, industrial, and governmental brewing science communities to present research within the focused theme of the sensory evaluation of hops as an ingredient in brewing. Readers will find new information on aromatic influences of hops on beer flavor that are derived from hop oils, glycosides, and photo-oxidation products of hop acids. The nature by which volatile hop components and non-volatile hop glycosides affect beer flavor is examined. The role of hop polyphenols and hop acids on beer flavor stability is discussed along with their impact on beer bitterness and flavor stability. T he USDA hop breeding team synthesizes the role of genetics and breeding to achieve brewing-specific traits and develop new hop varieties.
