∙ 14y agoCoffee is not a pure substance, it is a mixture, meaning it is made of two ore more pure substances that have been physically combined. Unbrewed coffee is a heterogeneous mixture or a colloid since it has large to medium sized particles that can be separated by hand. Brewed coffee is a homogeneous mixture since all the particles are evenly mixed.
