alcoholmeter is used to find the alcohol percentage of alcohol by
volume (abv) in a completely dry or distilled liquor that has no
dissolved sugar. It does this by measuring the density of the
liquid compared to that of alcohol; any residual sugar or other
cause of change to the density will result in a false low
is often a minute amount of unfermented sugar following standard
fermentation, along with dissolved carbon dioxide and spent yeast
or solids remaining after fermentation, it is very difficult to
obtain an accurate reading of the abv in such a liquid. In
addition, an alcoholmeter is increasingly difficult to read at
lower alcohol percentages, compounding the problem.
reason, it is suggested that you use an alcoholmeter only for the
testing of distilled spirits.
The use of an
alcoholmeter is very straight forward. Pour a sample of the spirit
to be tested into a tall glass or high chemical tolerant plastic
cylinder, leaving enough space for the alcoholmeter to disperse the
liquid. In order to obtain the most accurate reading possible, try
to ensure that the liquid is as close to 68 deg F (20'C) as
possible, as this is the temperature that the alcoholmeter has been
calibrated to (should your alcoholmeter be calibrated to a
different temperature, which should be stated on the meter, ensure
that your liquid is at the quoted temperature). Place your
alcoholmeter in the sample and spin it do dislodge any bubbles that
may have been in the liquid, and could potentially cause the
alcoholmeter to float slightly higher, resulting in a low reading.
Read the mark where the liquid level crosses the stem of the
alcoholmeter. This is your percentage alcohol by volume.
