You can also use this tool in a slightly different way. You may use liters, tons, tonnes, barrels, teaspoons, etc. Please note that Pearson’s Square and the equations presented here are not specific to the English system of units. Just to be sure we did this correctly we can add the volume of wines A and B together and we get a total of 6 gallons. To get these quantities into units of measurement that are actually useful we can calculate the percentage of each as follows: Mixing 3.5 parts of wine A with 1.5 parts of wine B will result in a final alcohol content of 13.5%. You may have noticed that the units for D and E are labeled as “parts”. So even though B – C is a negative number take it as positive for the purposes of this calculation. The vertical lines “||” are the symbol for absolute value in case your algebra is rusty. Here’s how it lays out in the Pearson Square. Our goal is to blend these two wines together to produce 6 gallons of wine that has an alcohol content of 13.5%. Let’s say we’ve got a 15% ABV wine and a 10% ABV wine. This has been sort of abstract so let’s it… Using the Pearson Square to Blend Wines When combined in these amounts you will have a wine with the desired alcohol level “C”. “E” represents the amount of wine “B” you need. With this information you can calculate “D” which is the amount of wine “A” that you need. Keep in mind that you can use this for more than just blending wines of different alcohol levels. “C” represents your target alcohol level. The variable “A” represents the alcohol content of one of your blending wines while “B” represents the alcohol content of the other. If we have two wines of different alcohol levels we can use the square to determine how much of each wine to mix together to come up with a blend that has an alcohol level of our choosing. Pearson’s Square is actually a simple tool for calculating the ratios of two different wines that when mixed together result in a mixture that has the characteristics you desire. So how does this magical tool work? Let’s find out. blend wine and brandy when fortifying a wine.calculate sugar additions to increase a finished wine’s alcohol content.blend wines of different degrees of sweetness.blend wines of different acidity to create a more balanced wine.It doesn’t end with alcohol though, Pearson’s Square can be used to: This tool can be used for blending a wine of high alcohol and one of low alcohol content to produce a wine with a more reasonable alcohol level. Luckily there’s a handy tool you can use, Pearson’s Square, for determining the proper proportions needed to create the right balance in your final wine. ![]() ![]() Blending wine to adjust wine chemistry can be a little tricky.
