Refractometer/Brix Reading

A refractometer measures soluble sugar
content of mix, expressed in percentage
weight. This is normally referred to as a
"Brix Reading." The typical refractometer
uses a scale from 0% to 32%.
Adjust the refractometer according to
the manufacturer's instructions.
NOTE: A refractometer is a delicate
instrument and must be handled
with care. Never immerse the entire
refractometer in a cold drink. Cooling
the refractometer will cause it to give
inaccurate readings. A refractometer
cannot be used to read dietetic syrups.
1. Open the hinged side of the
refractometer and place a few drops of
mix on the slide.
Close the slide and look through the eye
piece, holding the refractometer toward
the light. A line will appear across a
graduated scale which indicates the Brix
level.
Acceptable Brix level is 11-13 on a
refractometer.

NOTE: Never go below 11 on the Brix
Reading.
Some experimentation may be necessary
before correct Brix and serving
temperature will be found. Generally,
the higher the Brix reading the lower
the serving temperature. Conversely,
the lower the Brix reading, the higher
the required serving temperature. If the
complaint concerns product appearance,
(ie. too runny or too stiff) always first
take a Brix reading of the mix because
variation in sugar content will have a
direct bearing on actual freezing point.
