Write all of the letters of the alphabet on your paper – one letter per line, vertical
Next to each letter, write any word that
comes to mind that relates to alcohol
The intoxicating substance found in beer, wine, liquor, and
liqueurs is ethyl alcohol (ethanol).
1. Ethanol is produced by the process of fermentation
a. yeast breaks down plant sugars into ethanol and CO2
until the “mash” reaches 14% alcohol
b. at 14% the alcohol kills the yeast
2. Beer and Ales - other ingredients added to dilute the alcohol
3. After fermentation, other beverages are heated and the vapors
are “condensed” and mixed with H2O to make the product.
Proof measures the % of alcohol in the beverage
A product that states “100 proof” is actually 50% alcohol
Higher proof = Greater effects on the body
Wines = 12 - 15% alcohol
Ales = 6 - 8%
Beer = 2 - 6%
*All percentages vary according to the specific product
Blood Alcohol Concentration, the ratio of alcohol to
total blood volume.
Tolerance = The nervous system adapts so that it takes more alcohol
to produce the same effects as it had on fewer drinks.
Blood Alcohol Concentration Chart
Activity: Organize the cards according to your beliefs of effects of
alcohol based on the number of drinks that a person has had.
It takes approximately 2 hours for the body to metabolize one
serving of alcohol.
1. Easily absorbed through the entire GI system
2. Mouth – tiny amounts
3. ~20% absorbed through stomach lining
4. ~80% absorbed through upper 1/3 of small intestine
Brainstorm with your group from BAC activity
2. Amount of alcohol consumed -
5. Carbonated beverages – absorbed more quickly than those w/o
6. Mixers – cause the pyloric valve to relax, thus allowing stomach
Contents to be “dumped” into the small intestine.
*Pyloric Valve = opening from stomach to small intestine
7. Mood – emotions affect how long it takes for contents to move
from the stomach to the small intestine. “Powerful Moods” cause
stomach contents to be dumped into the small intestine. = More rapid
