Fermented beverage is boiled at a
controlled temperature to extract and
concentrate the ethanol fumes
Ethanol Production - Distillation
2-43
Distilled
spirits is the name we give to high ethanol concentration beverages produced
by
distillation. These include rum, whiskey, gin, vodka, etc. The ethanol
concentration
of
distilled spirits usually is expressed in terms of proof, which is a number
corresponding
to twice the ethanol percentage.
For
example, an 80 proof beverage has an ethanol concentration of 40 %.

Common Drink Sizes
2-44
• Can
of beer – 12 ounces of fluid
@ 4 percent alcohol equals 0.48
ounces of pure ethanol
• Glass
of wine – 4 ounces of fluid
@ 12 percent alcohol equals 0.48
ounces of pure ethanol
• Shot
of whiskey (80 proof) – 1
and 1/4 ounces @ 40 percent
alcohol equals 0.50 ounces of
pure ethanol
•
Over the millennia during which people have used and abused ethanol, some
common
sized servings of the different beverages have evolved. Beer, for example,
is
normally dispensed in 12 ounce servings. Since beer has an ethanol
concentration
of
about four percent, the typical bottle or can of beer contains a little less
than one
half
ounce of pure ethanol.
• A
standard glass of wine has about four ounces of liquid. Wine is about 12 %
alcohol,
so the glass of wine also has a bit less than one half ounce of ethanol in it.
•
Whiskey and other distilled spirits are dispensed by the "shot
glass", usually
containing
about one and one quarter ounce of fluid. At a typical concentration of 40
%
ethanol (80 proof), the standard shot of whiskey has approximately one half
ounce
of
ethanol.
Therefore,
as far as their alcoholic contents are concerned, a can of beer, a glass of
wine
and a shot of whiskey are all the same.

Alcohol is a CNS Depressant
2-45
Alcohol is the most
abused drug in the
United States
Ethanol
is a Central Nervous System Depressant. It doesn't affect a person until it
gets
into
their central nervous system, i.e., the brain, brain stem and spinal cord.
Ethanol
gets
to the brain by getting into the blood. In order to get into the blood, it has
to get
into
the body.
There
are actually a number of different ways in which ethanol can get into the body.
It
can
be inhaled. Ethanol fumes, when taken into the lungs, will pass into the
bloodstream
and a positive blood alcohol concentration (BAC) will develop.
However,
prolonged breathing of fairly concentrated fumes would be required to
produce
a significantly high BAC. Ethanol could also be injected, directly into a vein;
it
would
then flow with the blood back to the heart, where it would be pumped first to
the
lungs
and then to the brain. And, it could be inserted, as an enema, and pass quickly
from
the large intestine into the blood. But none of these methods are of any
practical
significance,
because alcohol is almost always introduced into the body orally, i.e., by
drinking.
