The Microbiology of Beer Christine L. Case, Ed.D. Biology Professor Skyline College : My home page : The exact origins of beer are unclear. It is apparent, however, that beer. Beer may have been important because it provided an alternative to drinking contaminated water or because it provided a palatable use for grain that had gotten wet and would otherwise have spoiled. The December 19, 1620 entry into the. Reason No. 102 why I love food science: the microbiology behind beer. The American Academy of Microbiology has just posted a 12-page report, “ FAQ: If the Yeast Ain't Happy, Ain't Nobody Happy: The Microbiology of Beer' that explains the relationship between beer and it’s main microorganism, yeast.

This report is based on the deliberations of 18 participants who convened for a day to discuss the relationship between microbiology and beer brewing. View/Download this Report. We would welcome you sharing our report. If you do, please link to this page, and not the PDF. What do microbes have to do with beer? Everything! Because the master ingredient in beer is yeast – a microbe – and every step in the brewing process helps the yeast do its job better. A new freely-available report. Download as PDFMost beer drinkers likely don’t give much thought to the mechanics behind brewing a quality beer; yet, it is a fascinating process. A recent lecture series sponsored by the American Society for Microbiology (ASM) described the operations involved in making beer and the role microbes play in brewing beer.1 The recent event, entitled Read the rest of this article. Interesting Beer History A 3. Sumerian poem honoring the brewing goddess Ninkasi contains the oldest surviving beer recipe, describing the production of beer from barley via bread. The Babylonian Code of Hammurabi required that tavern- keepers who diluted or overcharged for beer should be put to death. During medieval times fasting monks drank beer for nutrition as well as a tasty drink. Historians report that each monk was allowed to have 5 liters of beer per day. The Pilgrim Fathers landed at Plymouth Rock, instead of further south, partly because they were out of beer. Journal entry dated December 1. We could not take time for further search or consideration our victuals being much spent, especially our beer". Foods produced using microorganisms - cheese, buttermilk, sour cream, yogurt - bread (pizza crust) - soy sauce, miso, vinegar - sauerkraut, kimchi, pickles - beer, wine, rootbeer, ginger ale (actually the soft- drinks are now prepared commercially without brewing or fermentation) 6. Micro organisms too small to be seen without a microscope 0. Bacteria (kingdom Monera) single- celled Yeasts, Molds, Mushrooms (kingdom Fungi) single- celled (yeasts) or multicellular Protozoans (kingdom Animalia), single- celled animals Viruses, Prions (nonliving particles) Magnified 1. The microorganisms that produce beer are a. Beer is produced using the natural process of a. Fermentation. Part of the process which microbes use to produce ENERGY when oxygen is unavailable (anaerobic) lactic acid or alcohol is a byproduct milk products lactose ? CO2 Et. OH 1. 0Beer Production 1. Barley germinated in water produces a sweet syrup, termed malting. The barley malting process lasts for forty- eight hours. The sprouted barley grain (malt) is then roasted. A longer, higher roast produces a darker, more flavorful barley, hence a darker, more flavorful beer. Conversely, a lower, shorter roast produces a less flavorful beer. The roasted barley kernels are ground and mixed with water to form a mash. Enzymes in the grain convert the starches of the mashed grains into sugar. The sweet liquid is called a wort. Wort is boiled and Hops are added to create a hopped wort. ![]() The liquid is cooled to the right temp yeast are added. Louis Pasteur, 1. Beer wine was going sour! Showed that fermentation was an anaerobic process carried out by microorganisms Showed certain organisms produced lactic acid, others produced alcohol Discovered that heating the solution prevented souring of wine during aging, extended shelf life of beer milk. Later germ theory of disease, anthrax rabies vaccines 1. Pasteurization revolutionized the beer industry it also changed the taste but since beer could now be bottled and shipped all overconsidered a minor detail Draft beer nonpasteurized Bottled beer pasteurized Filtration - 1. The Microbiology of Beer. In the Netherlands (where the LumiByte headquarter is located) we love our beers. In fact the Netherlands are home to over a 100 breweries. ![]() ![]() Adolph Coors company figured out how to filter out leftover yeast bacteria without heat, thus preserving flavor Japanese developed a better ceramic filter Sapporo Draft Anheuser- Busch company adopted filtration methods Miller Draft Most American breweries still employ pasteurization methods. Q Whats the alcohol content of typical American beers? A 3. 6- 3. 8 by weight (4- 5 by volume) Q What about "light" beer? A between 2. 3 and 3. Q Why is the alcohol content of beer so low? A CO2 build up (too much pressure will stop yeast from fermenting) Yeast runs out of sugar (can add sugar to increase alcohol content) But - at 1. ETOH the alcohol level kills the yeast 1. Assignment. Due in cluster Tuesday morning, 1. Minimum of 2 page LLOG (described below) Minimum of 1 full page to consist of one topic related to beer production that you do research and expand on go into further depth (at least 3 credible sources) ½ page on one aspect related to the cultural importance of fermentation ½ page on take- away, hardest thing, connection, competency. Remember CONCISENESS and QUALITY CONTENT are important qualities in writing about science!
