Beer

Beer History No True Beginning Sumerians of Ancient Mesopotamia – First record of “Beer” – Cuneiform – Accidental discovery

U.S. Beer Timeline : Beginning of Brewing in America -The first brewery in New World established at current day Manhattan : Brewing Increases in Popularity -132 Breweries are producing 185,000 barrels of beer : Brewing Becomes a Viable Industry -IRS began taxing beer to finance the government during the Civil War Breweries are producing 6 million barrels of beer : Prohibition Days -American Brewers Association formed -During this time beer was outlawed

Timeline Continued : Brewing is Revived -Prohibition was lifted : After WWII, Prosperity Continues -Aluminum Can Introduced -Ring pull can introduced : More Growth & New Aspects -Becomes legal to put the alcohol content on the bottle 2000-Present: Still looking good -1,458 breweries product 6.2 million barrels of beer

Beer Materials Barley Hops Yeast Water

Barley Hordeum spontaneum Wild Barley Hordeum distichon; 2 rowed barley Hordeum vulgaris; 6 rowed barley Monocot; Poaceae family One of the oldest cultivated crops in the world Superb flavor for beer

Barley 25% of barley produced is used for alcohol – 80% beer – 14% distilled alcohol products – 6% malted food products

Hops Humulus lupulus Dicot; Cannabaceae family Minor ingredient used for adding bitterness and aroma to beer Classified as bittering added at the beginning of brewing or as aroma hops added at the end of brewing

Yeast Fungi Ale yeast (top fermentation) Saccharomyces cerevisiae -Ales, Porters, Stouts, and Wheat beer Lager yeast (bottom fermentation) S. carlsbergensis -Pilsners, Bocks, and American Malt Liquors

Water Mineral content contributes to beer flavor Beer is 90% water Munich-water is high in carbonates-dark beer Dortmund-water is high in carbonates and chloride-lagers and pale ales

Typical Beer Making Process (Bottom Fermentation) Make Wort Brew Fermentation Secondary Fermentation Natural Carbonation

Making Wort 2 gallons hot water degrees F Add 12 oz. crushed grains Steep for 20 minutes Add 6.6 lbs. plain light malt extract

Brewing Add 1.5 oz. bittering hops to boiling wort Allow to boil ~ 1hour Add 1.5 oz. aroma hops (finishing hops) Rapidly cool wort ~ 70 degrees Dilute wort with water to specific volume (5 gallons)

Fermentation Process Add 1 packet yeast to cooled wort Let solution ferment (7-10 days) while maintaining constant temperature ~ 70 degrees Pour (siphon) beer off of yeast

Secondary Fermentation (Optional) Let beer sit (microscopic yeast) Pour (siphon) beer off of yeast

Natural Carbonation Add 5 oz. of priming sugar Put beer in container Let sit ~2 months for full carbonation

Chemistry Barley has a high complement of enzymes used to convert starch into simple sugars and protein for yeast nutrition. Hops has bacteriostatic activity that inhibits the growth of gram positive bacteria in the finished beer. Yeast convert fermentable sugars into alcohol and carbon dioxide as a by-product.

Yeast Chemistry yeast + sugar  pyruvic acid + CO 2 pyruvic acid + 2 electrons  ethanol (drinking alcohol) Alcohol is a by-product of yeast performing glycolysis in anaerobic energy conversion

Most common alcohol consumption problems Alcohol poisoning -when parts of the brain shut down because of the high amount of alcohol in the blood stream Hangovers -Dehydration-headache -Inflammation of esophagus-heartburn -Acid accumulation in stomach-nausea -Low blood glucose levels-shakes, dizziness, blurred vision & tiredness -Intestinal inhibition- diarrhea

Problems continued Binge Drinking – Studies suggest that binge drinking rates are declining.

Problems continued Consuming alcohol during pregnancy can cause Fetal Alcohol Spectrum Disorder (FASD) – Fetal Alcohol Syndrome (FAS) – partial Fetal Alcohol Syndrome (pFAS) – Alcohol-Related Birth Defects (ARBD) – Alcohol-Related Neurodevelopment Disorder (ARND)

Problems Continued Drinking and Driving “In 2005, 16,885 people died in alcohol-related motor vehicle crashes, accounting for 39% of all traffic-related deaths in the United States” (NHTSA 2006). “An alcohol-related motor vehicle crash kills someone every 31 minutes and nonfatally injures someone every two minutes” (NHTSA 2006). “Each year, alcohol-related crashes in the United States cost about $51 billion” (Blincoe et al. 2002).

Summary Beer has been around for a very long time. Alcohol is a large part of out society as a whole. Materials – Barley, Hops, Yeast, and Water Process – Make wort, brew, ferment, secondary ferment, natural ferment Chemistry – Yeast forms alcohol Benefits – Jobs (brewing, advertisement, selling, delivering etc) – People enjoy drinking beer Drawbacks – Health related problems – Irresponsibility of drinkers
