culture for thousands of years from its
prehistoric inception to its many uses

countless effects on our cultures and
our lines throughout the course of human

northern China it was a kind of wine
made from fruit honey and rice about a
thousand years later in the Central
Asian country of Georgia the oldest wine
made exclusively from grapes was
produced and around the same time in the
Middle East
the earliest beer was being made from
barley no matter where or what types of
alcoholic beverages are produced they
all share a similar chemistry the type
of alcohol found in beverages such as
beer wine and spirits is called ethyl
alcohol or ethanol ethanol is produced
through fermentation a process in which
microorganisms usually bacteria or a
fungus called yeast cause organic
material to decompose by decomposing
sugars in the organic material are
converted into carbon dioxide and
ethanol the ingredient that makes
alcoholic beverages intoxicating
alcohols intoxicating effects are due to
its role on the human central nervous
system moderate amounts of alcohol
trigger the release of neural chemicals
such as dopamine serotonin and
endorphins in the brain this decreases
anxiety increases happiness and
depresses the brains inhibitory
activities
