A refractometer is a measurement tool to measure the concentration of transparent or dissolved substances of a liquid. Light is radiated through a liquid solution, which on the way is broken or reflected. Depending on the concentration of the substances, the speed of the light differs. As a result, a concentration value (TDS value in percent) can be measured. TDS stands for total dissolved solids.
Thus, a refractometer enables the reproducibility of certain extractable data and the elaboration of brewing recipes.
It gives us a hint if a coffee is over- or underextracted.
The values signal changes of the material (e.g. the mills through grinding discs becoming blunt), of water (soft or hard water dissolves more or fewer substances of coffee), of pressure (e.g. decrease of pressure on espresso machine through calcification etc.), or of the ageing of coffee.
Different types of espresso machines and filters can be compared with their extraction results, as well as with Tamping- techniques, filling levels of portafilters etc.
different coffees (origin, level, variety) can be rediscovered if they are confronted with consistent, external parameters during brewing and different extraction values are measured.
