1. Understand the Proper Grind
Grinding coffee fresh with an espresso grinder, like our Rocky, is important for beverage quality. Remember: an espresso machine requires an appropriate espresso grinder. Not all grinders can achieve the level of fine grind you need for good espresso.
The flow rate, or the speed of the espresso's flow from the portafilter, can change based on environmental circumstances. These include room humidity, coffee's roast age or level, the amount of beans in your hopper and many other variables.
While it is possible to use pre-ground coffee, it’s important to note that it has lost gases that contribute to crema: the oily and blonde top-layer of espresso. The advantage of a grinder is that you can control the flow rate each time you grind unlike pre-ground coffee that is fixed to a certain grind size.
