Both oscillatory and rotational measurements on the film formation process and on interfacial rheological properties of the final film of coffee samples with different concentrations are presented. As higher the concentration as faster the film formation process is, whereas the concentration does not have a large effect on the visco‐elastic properties of the final films. Two geometries, a biconical geometry and a Du Nouy ring have been employed. The presented results show that interfacial shear rheology allows detailed investigations on coffee films. Although with a Du Nouy ring it is possible to measure the qualitative behavior and relative differences only the biconical geometry is sensitive enough to test weak films and to reveal real absolute values for the interfacial shear rheological quantities.
