Just how does one try to make sense to a guy that believes that the term Brix means sugar and that the only use for the refractometer is to measure sugar! lol! These people are a riot!
As all the definitions I showed you prove, brix is a measurement of sugar in solution. And even your link was discussing measuring the natural sugars extracted from the coffee beans then using a mathematical formula to determine the total dissolved solids (TDS) in the solution. So you provided the evidence that you were wrong on several fronts. GET A CLUE!!!:
