Exploring aldehyde release in beer by 4-vinylpyridine and the effect of cysteine addition on the beer's pool of bound aldehydes Ghent University KU Leuven
Elements and beers and effect of some metals ions on colloidal stability of beer Ghent University
Many ions have to be in a certain concentration range to be suitable for the brewing process and / or the subsequent beer. In case the concentration of some metal ions, especially of Mn2+ and Fe2+, are too high chill haze can be formed. This causes economic losses for the brewing industry. Chill haze is due to the precipitation of protein-polyphenol-metal complexes under inadequate storage conditions. Metals ions in beer originate from water, ...
The politics of beer: analysis of the congressional votes on the beer bill of 1933 KU Leuven
© 2017, Springer Science+Business Media, LLC, part of Springer Nature. Nine days after he took office in March 1933, Franklin Roosevelt asked Congress to amend existing federal Prohibition policy so as to allow for the sale and consumption of 3.2% alcohol beer. Over the following 8 days, the so-called “beer bill” was proposed, debated, passed and signed into law. This study analyzes the political decision making behind one of FDR’s earliest New ...
Economic perspectives on craft beer: A revolution in the global beer industry KU Leuven
© The Editor(s) and The Author(s) 2018. This book investigates the birth and evolution of craft breweries around the world. Microbrewery, brewpub, artisanal brewery, henceforth craft brewery, are terms referred to a new kind of production in the brewing industry contraposed to the mass production of beer, which has started and diffused in almost all industrialized countries in the last decades. This project provides an explanation of the ...
Estrogenicity of beer: the role of intestinal bacteria in the activation of the beer flavonoid isoxanthohumol Ghent University
Reproducibility Trials in a Research Brewery and Effects on the Evaluation of Hop Substances in Beer Part 2: Reproducibility in Moderately Aged Beers KU Leuven
The good reproducibility of the 2 hl research brewery as proven in our previous study has been now reviewed after storing the beers at 0 °C and deep frozen (at – 24 °C) for 240 days. Except for some Strecker aldehydes all other ageing aldehydes, fermentation by-products and particularly the analyzed hop aroma compounds show good stability at 0 °C. The analytical standard deviations of the three-fold determinations are even a little lower than ...
Influence of Beer Characteristics on Yeast Refermentation Performance During Bottle Conditioning of Belgian Beers KU Leuven
Although bottle conditioning of beer seems a rather simple process, problems often arise in industrial practice. Lack of process control can result in variable batch-to-batch quality, while constant product quality should be maintained anytime. In the present study, the refermentability of several Belgian beers was investigated to reveal important beer-related compounds influencing overall yeast fermentation performance during bottle ...
Optical measurements and pattern-recognition techniques for identifying the characteristics of beer and distinguishing Belgian Beers Vrije Universiteit Brussel
A miscellaneous assortment of 86 beers was characterized using non-destructive, rapid and reagent-free optical measurements. Diffuse-light absorption spectroscopy performed in the visible and near-infrared bands with the use of optical fiber spectrometers was tested innovatively to gather turbidity-free spectroscopic information. Furthermore, conventional turbidity and refractive index measurements were added in order to complete the optical ...
Peer effects and the rise of beer in Russia KU Leuven
Between 1996 and 2007, per capita beer consumption in Russia more than quintupled, making beer the most important alcoholic drink in Russia today and transforming Russia into the world's third largest beer market. We study the role of peer effects in this rapid adoption of beer. In particular, we argue that the initial 'shocks' of improvements in quality and increased advertising were magnified through peer effects. Using detailed data from the ...
