Coffee sample placement
Since coffee samples that have just been roasted or are still temperature-
charged will release infrared light. This may interfere with the sensor resulting
in inaccurate measurement. Make sure the coffee sample has cooled down to
room temperature before using.
When the sample coffee is not properly placed, the measurement result
can become inaccurate. The placement density of the sample and whether or
not it levels with the edge of the cup when filling and flattening the sample
cup are the two most important points that will affect the measurement
accuracy. When placing coffee in the sample cup, fill as much as possible to
reduce any gap in the content. Then use a scraping tool to flatten the top to
the height of the cup edge level without special weighing.
The degree of coffee grinding will also affect the measurement result. The
SCA cupping standards requires 70 to 75% of ground must pass through 20
mesh sieve. The ground is then flattened to fill the sample cup. Make sure
there is no gap in the content and is level with the cup edge. If there is no
correct sieve available, you can fix each grinding scale for comparison. This will
