Their classes are focused on the science behind brewing, but all have a hands-on brewing experience, and even the Certificate is designed to provide an overview of the biochemistry, microbiology, technology, and business of craft brewing.
The invention of bread and beer has been argued to be responsible for humanity's ability to develop technology and build civilization. The earliest chemically confirmed barley beer to date was discovered at Godin Tepe in the central Zagros Mountains of Iran, where fragments of a jug, from between 5,400 and 5,000 years ago was found to be coated with beerstone, a by-product of the brewing process.
In some sectors brewers are reluctant to embrace new technology for fear of losing the traditional characteristics of their beer. For example, Marston's Brewery in Burton on Trent still uses open wooden Burton Union sets for fermentation in order to maintain the quality and flavour of its beers, while Belgium's lambic brewers go so far as to expose their brews to outside air in order to pick up the natural wild yeasts which ferment the wort. Traditional brewing techniques protect the beer from oxidation by maintaining a carbon dioxide blanket over the wort as it ferments into beer.
Vienna Lager is an outstanding example of a revolution in beer brewing that started in the 1830s. When Austrian brewer Anton Dreher travelled to England and Scotland, he learned about British brewing technology that was mostly unknown in Continental Europe at the time.
This volume surveys the most recent discoveries in brewing microbiology, with an emphasis on omics techniques and other modern technologies. Discoveries in these areas have furthered our knowledge of brewing processes, with practical applications from barley growth and malting to yeast management, strain selection, fermentation control, and quality assurance. The chapters, written by experts in the field, aim not only to illuminate recent progress, but also to discuss its impact on brewing practices. Topics covered include the physiology, fermentation, taxonomy, diversity, typing, genetic manipulation, genomics and evolution of brewing yeasts. Further areas covered include the fungal contamination of barley and malt, spoilage by lactic acid bacteria and gram-negative bacteria, and beer-spoiling yeasts. 2b1af7f3a8
