Specific Gravity Readings
This chart will help you determine the amount of
alcohol in your finished beer. To figure it out, simply subtract
the alcohol percentage that correlates with the final gravity
from the alcohol percentage that correlates with the original
gravity. For example, if you brew a beer with an original
gravity of 1.060 (7.500%) and you end up with a final gravity of
1.015 (1.625%), you have a beer with 5.875% ABV. When making
this calculation, remember to adjust for temperature using the
chart above.
For those of you who use degrees Plato rather
than specific gravity, those quantities have been added as well.
If you'd like to go from specific gravity to degrees Plato, or
vice versa, there are roughly 4 points of specific gravity for
every one-half degree Plato. Therefore, a specific gravity of
1.060 is also 15.00 degrees Plato (60 divided by 4).
