•1920-1933: Prohibition Days

-During this time beer was outlawed

Timeline Continued

1933-1945: Brewing is Revived-Prohibition was lifted

1945-1980: After WWII, Prosperity Continues-Aluminum Can Introduced

-Ring pull can introduced

1980-2000: 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

BarleyHopsYeastWater

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 bitteringadded at the beginning of brewing or as aromahops 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 160-170 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 + CO2

pyruvic acid + 2 electrons ethanol (drinking alcohol)

Alcohol is a by-product of yeast performing glycolysis in anaerobic energy conversion
