Why Delonghi Stilosa Porta Filter Size Is Necessary
I’ve found that the portafilter size on the Delonghi Stilosa is necessary because it directly affects how well the espresso extracts. When the size matches the machine’s design, I get more even water flow through the coffee grounds, which helps me pull a better shot with richer flavor and a smoother crema.
