Abstract:: The range of different nonvolatile constituents extracted from hops in highly hopped beers suggests that iso-alpha acids may not be the sole contributor to beers’ bitterness. Among brewers producing hop-forward beer styles there is a growing concern that the Bitterness Unit (BU) is no longer an accurate predictor of beer...

Creator:: Molitor, Richard W.
Abstract:: The biotransformation of hop aroma via yeast is a prominent topic in the brewing industry with considerable interest placed on how yeast can enhance volatile thiol production during wort fermentation. Three potent thiols are known contributors to tropical qualities in wine and beer aroma, specifically 3-mercaptohexan-1-ol (3MH), 3-mercaptohexyl acetate (3MHA),...

Creator:: Sereni, Anthony
Abstract:: Mouthfeel is one of the most important quality parameters of Chardonnay wines. Malolactic fermentation (MLF) is an important process in wine production, and influential to wine mouthfeel, with the reduction in acidity being particularly important for cool climate wines that generally have higher acidity such as Chardonnay. MLF is typically...

Creator:: Lafontaine, Scott R.
Abstract:: Historically, brewers have used dry-hopping (a cold extraction of nonvolatile and volatile chemicals from hops into fermenting or finished beer) to increase the microbial stability and shelf life of their beer. As hoppy beer styles have gained in popularity over the last decade (2007-2017), the objective of dry-hopping has turned...

Creator:: DuBois, Aubrey E.
Abstract:: The growth of Brettanomyces bruxellensis is a major cause of wine spoilage due tothe production of the volatile phenols 4-ethylphenol (4-EP) and 4-ethylguaiacol (4-EG), derivatives of p-coumaric acid and ferulic acid. During the winemaking process,some microorganisms can impact the concentration of the 4-EP precursors pcoumaricand coutaric acid (tartaric acid-esterified p-coumaric...

Creator:: Ruppel, Meghan L.
Abstract:: Nitrogen is a crucial nutrient required by yeast to successfully complete alcoholic fermentation. In particular, the concentration of yeast assimilable nitrogen (YAN) influences fermentation kinetics and the production of a range of volatile aroma compounds, both desirable and undesirable. YAN is naturally present in the grape, but producers can boost...

Abstract:: The human senses can be used as analytical tools to evaluate many different aspects of our daily lives. The use of our senses through organoleptic methods offers unique and powerful insights into the characteristics of different stimuli. Due to the unique function of the different sensory organs we use to...
