Frequently Asked Questions (FAQs)

What is a Brix refractometer?

Brix refractometers are the digital tools used to measure the sugar content of a liquid sample. If you bring up the sugar content, the refractive index also increases. Measuring this refraction allows you to measure the amount of sugar as well.

How is coffee extraction measured?

The refractometer measures the total dissolved solids, shortly known as TDS. This measurement is then used to find out the extraction yield by combining it with the weight of the coffee.

How to increase coffee TDS?

If you want your coffee to be stronger, you need to increase the amount of TDS. To do that, all you have to do is increase the coffee content compared to the amount of water.

How accurate are refractometers?

The accuracy of the refractometer can vary from one model to the other. A refractometer with a Brix measurement range of 0 to 30 percent is likely to have a precision between 0.2 to 0.3 Brix.

Is refractometer reading affected by temperature?

Refractometers depend on temperature for reading, so it definitely has an effect. A lack of temperature control can even cause issues with the instrument to the point that you need to replace it.
