Once you know the measured TDS, you can use a simple equation to determine the extraction percentage, which is the amount of coffee that it into your coffee. Calculation of Total Dissolved Solids (TDS) Correlation factor : Electrical conductivity (microsiemens per centimeter): Reset. When using Brix, I used to calculate TDS equals approximately 0.85 x Brix. The water that worked it’s way into the larger particles and stayed there has only contributed minimally, if at all. If you reduce the ratio, for example to 1:14 or 1:13, the brew will be stronger. The purpose of fabs, the fraction of absorbed water, is to find what fraction of the water is stuck inside the particles and remove it from our calculations. I’ve added standard equation results to the calculator to help with that. I published a work on the Staccato Espresso shot, and the main critique was that I didn’t use TDS as has been the standard in the barista world. The more scientific folks in the world of coffee will use a refractometer to accurately measure the number of solid particles in a brew to judge its extraction.
