Q: The manual suggests using coarsely ground coffee, but is it possible to use finely ground coffee in this unit?
A: It is not recommended to brew with finely ground coffee as the grinds may fall into the brewed coffee. However, if you wish to brew finely ground coffee, place a paper towel, napkin or coffee filter over the coffee basket before adding the coffee. Be sure to create a hole in the center for the stem.
