Grinding coarseness levels are an important parameter in coffee machines with an integrated grinder, allowing users to adjust the fineness of the grinding of the beans according to their preferences and the type of beverage being prepared. Different grinding coarseness levels affect the flavour and body of the coffee prepared. Finely ground coffee is suitable for espresso, while coarsely ground coffee is ideal for preparation methods such as filter coffee or French press. Choosing the right degree of coarseness of grind is crucial to achieve optimal extraction and beverage quality. Most coffee machines with an integrated grinder offer the possibility to set different grind coarseness levels to suit different preferences and beverages to be prepared.
