Coffee is a mixture and not a true solution because it is made by extracting a variety of chemical compounds from coffee beans that have been ground. Unless the filtering of the extracted coffee is perfect, the liquid phase will necessarily contain some of the finer particles (dust) from the grinding operation.

What is heterogeneous and homogeneous?
1. A homogenous mixture is that mixture in which the components mix with each other and its composition is uniform throughout the solution. A heterogenous mixture is that mixture in which the composition is not uniform throughout and different components are observed.
What kind of mixture is black coffee?
Black coffee is a homogeneous mixture.
What makes a coffee a solution?
At a very basic level, brewed coffee is a solution which results from combining ground coffee beans and hot water. In this interaction, the coffee beans operate as a solute, or substance which is dissolved to create a solution, and hot water acts as a solvent, or the substance used to dissolve the solute.
What type of mixture is coffee powder and water?
Why is coffee a heterogeneous mixture?
