The gauge needle, when positioned anywhere within the solid grey zone during
extraction process, it indicates the espresso has been extracted at the ideal pres-
sure.
The gauge needle, when positioned in the lower zone during the extraction
process, it indicates the espresso has been extracted with insufficient pressure.
This happens when the water flow through the ground coffee is too fast during
extraction, the extracted espresso is too much water, and lacks crema and flavor.
The reasons why under extraction include the ground coffee are too coarse and/or
insufficient ground coffee in the filter and/or under tamping.
