Executing the perfect cup of coffee
Executing the perfect cup of coffee would be incredibly difficult without proper knowledge of the technical considerations, as mastering the techniques of handling and setting a restaurant coffee grinder may seem to be a mammoth task on initial impression.
Nevertheless, with specific instruction and direction, this mastery can be honed and passed on over time.
To begin, one must understand that restaurant coffee grinders are made up of two burrs. The top burr needs to be adjusted to ensure you achieve the desired granularity of your coffee bean grind, as the bottom burr cannot be moved.

The fineness of the ground coffee is determined by how close the two burrs are to each other, meaning that the closer the two burrs are, the finer the grind, whereas the further apart, the grind will be coarser.
The top burr can be moved in either direction, as it is fixed to the top of the grinder, which will also affect the required output. Check the markings on the grinder to be sure of which way to turn the burr to achieve your desired grind.
If the output of the coffee grounds are extracted in under twenty-seconds and the grounds happen to be too coarse, hot water runs through the ground to quickly. However, if the ground extraction takes longer than thirty seconds and the ground is too fine, over extracted coffee will not deliver the same great quality feel as the ideal cup of coffee.
Some restaurant grinders on the market feature indicators on their burrs that facilitate the adjustments of the machine, such as numbers. You should only ever adjust your machine gradually, moving only one click at a time.
Temperature can impact and affect the fineness of the coffee grounds produced, and regular espresso checks should be made throughout the day to ensure that the ground coffee produced by your grinder is creating high quality coffees and optimum results.
