How To...Use The Pearson Square.
The Pearson Square is a simple equasion to allow you to determine a specific gravity, or ph level for your wine.
The best way to explain this is with an example. In this case you have a wine that is too sweet and you want to blend with another dryer wine but don't know how much of each to use. This has nothing to do with volume.
A). Represents the gravity of one of your dry wine.
B). Represents the gravity of your sweet wine.
C). In the middle represents the final gravity you want.
The difference of "C" from "A" is "E".
The difference of "C" from "B" is "D".
Now this tells you how much of each wine is needed to achieve the gravity you want. "E" is the number of parts of "A" that you need and "D" is the number of parts of "B" that you need.
In the diagram above "A" is 1.000 a dry wine.
"B" is the sweet wine 1.010
You would like to have your wine at 1.008
After doing the math, "D" is 2 and "E" is 8
You need two parts of the sweet wine blended with eight parts of the dry wine, or one to four.
