  • Aroma qualities of raw hops and hops in beer by trained panel free-choice profiling

    Creator:
    Stucky, Gregory J.
    Abstract:
    Hops contribute many desirable aromas to beer. Traditionally hop aromas have been described by the point of addition in the brewing process (dry-hop, finish-hop, or kettle-hop). The compounds present in the oil provide a wide range of aroma qualities. Since the composition of the oil is different for each hop...

  • Analytical and sensory evaluation of hop varieties

    Creator:
    Sanchez, Nora B.
    Abstract:
    The German hop Hallertauer, hallertauer is highly valued because of its "noble aroma", but it has a very low yield when cultivated in the U.S. Two new crosses of Hallertauer, U.S.D.A. 21455 and 21459, have high yields and promising aroma characteristics. In order to predict sensory properties of beers as...

  • Factors that Influence the Aroma and Monoterpene Alcohol Profile of Hopped Beer

    Creator:
    Sharp, Daniel C.
    Abstract:
    Hop aroma in beer is related to the unique compositional chemistry of the hops used in the brewing process. While the range of these compositions is quite diverse and primarily dependent on hop cultivar¹, other studies have also shown that cultivation, seasonality, harvesting², processing³⁴, and storage practices⁵⁶ contribute to differences...

  • A study of factors affecting the extraction of flavor when dry hopping beer

    Creator:
    Wolfe, Peter Harold
    Abstract:
    This work set out to examine the methodologies of dry hopping, compare different hop materials, and look at the extraction behavior of different types of hop compounds. This work consists of two discrete studies, where the first study informed the design of the second. The first study measured the concentrations...
