Differences between program values and printed values

Postby Df39 » Tue Nov 01, 2011 6:14 am

I just installed BeerTools and entered the data from first brew. When printing out the info sheet afterwards I ran into the following discrepancy:

Program values for ABV: Apparent: 4.62%
Real: 5.91%
Printout values for ABV: Apparent: 5.91%
Real: 4.62%

Any explanation or is this a bug ?

In addition, in the program I entered the following values:

OG reading: 1.060
TG reading: 1.015

The program then listed the following:

Original extract: Apparent: 1.060
Real: 1.060
Terminal extract: Apparent: 1.015
Real: 1.023

Again - any explanation ?

Thanks in advance[size=12][/size]

The ABV and ABW values are not part of the Apparent and Real columns. Alcohol doesn't have an apparent and real value. That's why ABV and ABW appear after their respective values.

The measured terminal gravity is always "apparent" because of the effect alcohol has on fluid density. Real extract factors in the effect of alcohol and is higher than the measured value.
